1. Prescribed use The complete radio-controlled radiator thermostat system comprises three components: • ‘FHT80B-3’ heating control/thermostat • ‘FHT8V’ valve operating mechanism • ‘FHT80TF-2’ door/window contact sensor The system is used for temperature control in individual rooms in which the heat that dissipates from radiators is controlled by reducing the flow of hot water in the heating system.
3. Explanation of icons The icon with a lightning flash in a triangle is used to alert you to potential personal injury hazards such as electric shock. An exclamation mark in a triangle indicates important information in these operating instructions which must be observed without fail. The ‘hand’ symbol provides special information and advice on operating the device.
4. General information The radio-controlled radiator thermostat system has a number of advantages compared with simple mechanical thermostats: • The system is separated into radiator-mounted valve operating mechanisms and freely positionable operation and control units (the ‘FHT80B-3’ heating control supplied here, for example), which makes it easy to carry out all the necessary settings.
Changes (‘Window open’ or ‘Window closed’) are signalled to the heating control within a time period of about 1 minute. This allows the heating control to adjust the temperature after an average of 30 seconds, in order to save energy when a room is aired, for example.
c) Information on the range • The transmission power is less than 10 mW, much below that of a mobile phone which may have a transmission power 200 times as great. Adverse effects on sensitive people and animals are not to be expected. • The wireless radiator thermostat system uses the 868 MHz range, which is also used by other radio services. Therefore devices that operate on the same or neighbouring frequencies may restrict both its operation and its range.
5. Safety instructions The product’s guarantee becomes invalid if the product is damaged as a result of failure to observe these operating instructions. We do not assume any liability for any resulting damages! Nor do we assume liability for damage to property or personal injury caused by improper use or failure to observe the safety instructions.

8. Mounting the ‘FHT80B-3’ to a wall a) Choosing a suitable installation location Choose a suitable location for mounting the ‘FHT80B-3’ heating control.
• Fix the wall holder into place using, for example, the enclosed screws. Make sure that the two recessed slotted holes for the screws point in your direction. • Before attaching the heating control to the wall holder insert the batteries, if you have not done so already. See section 6, page 11. • You can now slide the heating control into the wall holder from above.
9. Set date and time • If there is a protective film over the display, remove it first. • If no batteries have been inserted yet, follow the instructions in section 6, page 11 to insert them. After inserting the batteries, an automatic display test is performed (all segments and readouts of the LCD briefly appear). After the display test you can set the year, month, day, hour and minute on the heating control. Use the scroller to change the displayed values.
• The day is displayed: MO DI MI DO FR SA SO Figure 5 12 6 0 24 18 Use the scroller to set the day and confirm your setting by pressing the ‘PROG’ button. • The hours are displayed: MO DI MI DO FR SA SO Figure 6 12 6 0 24 18 Use the scroller to set the hour of the day and confirm your setting by pressing the ‘PROG’ button.
• The LCD then displays the current security code and ‘120’. • The heating control counts down from ‘120’ in steps of 1 second and then returns to the normal operating mode. During this time the heating control cannot be operated. The heating control now synchronises its operation with the valve operating mechanisms. Please make a note of the displayed security code on a slip of paper and write the name of the room, in which the heating control is installed, underneath the code.
10. Mounting the ‘FHT8V’ valve operating mechanism To save you from having to laboriously read through several user manuals (heating control and valve operating mechanism) we have included information on how to mount and start up the ‘FHT8V’ valve operating mechanism on the following pages. The valve operating mechanism is not supplied with the heating control and must be ordered separately. a) Removing the old thermostats • Remove the old mechanical thermostats.
c) Mounting the valve operating mechanism to the radiator • Manually turn the coupling nut to fasten the valve operating mechanism to the valve (‘1’ in the figure on the right). When using ‘Danfoss’ valves mount one of the enclosed adapters to the valve first. The figures 12a, 12b, and 12c on the next page show the adapters that have to be used for each valve. Additional adapters for other valves may be purchased separately. • Briefly press the button (2) on the valve operating mechanism once.
Examples of ‘Danfoss’ adapters: Figure 12a, type ‘RA’ Figure 12b, type ‘RAV’ Figure 12c, type ‘RAVL’ After attaching the adapters for valves of the type ‘RAV’ and ‘RA’ to the valve body, the adapters should be fastened using the enclosed screw and nut. For valves of the type ‘RAV’ you should also place the cylindrical extension piece onto the valve pin.
11. Mounting the door/window contact sensor ‘FHT80TF-2’ To save you from having to laboriously read through several user manuals we have included information on how to mount and start up the ‘FHT80TF-2’ door/window contact sensors on the following pages.
b) Installation notes • Magnetic contacts (reed contacts) are located inside the ‘FHT80TF-2’ door/window contact sensor both on the left and on the right side. This means that you can mount the supplied magnet either on the left or on the right side. A two-sided installation of 2 magnets (one on the left and one on the right of the door/ window contact sensor) is not possible! • Make absolutely sure that the lower edge of the magnet is 20mm away from the lower edge of the door/window contact sensor.
• You can attach several external sensors to the door/window contact sensor, such as when you have a wide window bank with several windows/doors. These external contacts must be NC (normally closed) contacts. When connecting several external NC contacts, they must be connected in series. See figure 14. NC contacts 1 2 3 Figure 14 Do not connect terminating resistors! • The maximum attainable wiring length is greatly dependent upon the cable used and the transmission resistance of the NC contacts.
c) Installing the ‘FHT80TF-2’ • Open the casing. Use an appropriately sized flat screwdriver to carefully push the catches on the left side of the casing approx. 1 millimetre inwards (‘A’), until the half shells separate. First press one side catch inwards and pull the casing approx. 1 millimetre apart at this location. Then press the other catch inwards; the casing now opens.
• If you are using external NC contacts, connect both cables (fed through the openings near screw ‘B’) with the screw terminals ‘KL1’ (position ‘D’ in figure 16). E Battery compartment for 2 AAA/micro batteries. + TA1 KL1 E + (‘normally closed’) B C D - D Screw terminals for external NC contacts D1 - C ‘TA1’ button A + A LED ‘D1’ B Opening for wall mounting (in the figure a screw is already inserted).
e) Setting the operating mode of the ‘FHT80TF-2’ In the delivery state the door/window contact sensor ‘FHT80TF-2’ only monitors the internal contact. When external contacts are also to be monitored (or only external contacts), then the operating mode must be adjusted accordingly.
12. Programming the system All the required system settings are preset to standard settings in the factory: • Heating phase: Comfort temperature 21 °C from 6.00 am to 11.00 pm • Lowering phase: Lowering temperature 17 °C from 11.00 pm to 6.00 am • ‘Window open’ temperature: 12 °C • Decalcification cycle: Saturday, 11.00 am All these settings may, of course, be changed and adapted to suit your individual requirements.
Use the scroller to set the desired comfort temperature. To confirm briefly press the ‘ ’ button. • The lowering temperature is then displayed on the LCD. The moon symbol ‘ ’ blinks. MO DI MI DO FR SA SO C 12 6 0 Figure 18 24 18 Use the scroller to set the desired lowering temperature. To confirm briefly press the ‘ button. • The LCD displays the ‘Window open’ temperature. The door/window symbol ‘ MO DI MI DO FR SA 6 12 18 ’ blinks.
b) Setting/changing the week profile The time for automatic switching between the comfort temperature and the lowering temperature can be programmed to different settings for each day of the week. This way you can adapt the desired room temperature to your individual lifestyle. 4 switching times (comfort temperature on, lowering temperature on, comfort temperature on, lowering temperature on) can be set for each day of the week. These 4 switching times can be different for each day of the week.
• The time when the comfort temperature will be switched on is displayed (the sun symbol ‘ 6:00 is displayed), in our example this is ‘6:00 6:00’ hrs: MO DI MI DO FR SA SO Prog Figure 21 12 6 0 ’ 24 18 Use the scroller to select the time when the appliance should begin warming up to the target comfort temperature. A scale for facilitating orientation appears on the bottom of the LCD (long lines = comfort temperature is active). Briefly press the ‘PROG’ button to confirm the starting time.
MO DI MI DO FR SA SO Prog 0 6 Figure 23 12 18 24 If you set the second comfort temperature time to ‘--:---:--’, the setting of the second --:-lowering temperature time is irrelevant, since nothing changes. Two different periods of comfort temperature can be set, for example, from 6.00 am to 9.00 am and from 4.00 pm to 11.00 pm. After the second lowering temperature time has been set and confirmed by pressing the ‘PROG’ button, the device returns to normal operating mode.
c) Operating modes Press the ‘FUNKTION’ button to change the operating mode. Press this button several times to scroll through the different operating modes: Automatic mode Manual mode Holiday/party function Figure 24 • Automatic mode In the Automatic operating mode (‘Auto’ appears in the LCD) the room temperature is controlled according to the program set for the day of the week. The temperature history for the current weekday is displayed on the bar scale in the lower part of the display.
Setting the holiday/party function: • Select this operating mode (suitcase symbol ‘ ’ appears in the display) with the ‘FUNKTION’ button and set the period of time this function is to be active. During the following 24 hours the temperature will be reduced in stages every 30 minutes (party function). Furthermore, the temperature will be reduced every day (holiday function). Set the day you will return from your holiday. As of 12 midnight on this day heating is then carried out using the normal time program.
e) Switching between comfort temperature and lowering temperature If a room is used at different times than set in the time program, you may change the temperature any time using the scroller. You can also switch directly from the comfort temperature to the lowering temperature by pressing the ‘ ’ button. f) Heating pause Switching off the heating during the summer conserves the actuator’s batteries and extends the service life of the batteries.
g) Closing the valve Select this operating mode, if you do not want to heat the room at all. The valve is closed and remains in this position. The valve is only opened, if the temperature drops below 5 °C (danger of freezing). The weekly decalcification cycle is still carried out. • Press the ‘FUNKTION’ button to switch to the ‘Manu’ operating mode. OFF OFF’ appears on the LCD.
i) ‘Window open’ detection The installed ‘FHT80TF-2’ door/window contact sensors require no operation. They detect when a window or a door has been opened and notify the heating control by radio signal accordingly. The heating control then reduces the target temperature to the ‘Window open’ temperature that has been set. Likewise, when all the windows are closed, the heating control is notified of this again by radio signal and restores the original temperature.
13. Special functions The heating control has several special functions. To access the special functions menu press the ‘PROG’ button until ‘Sond Sond’ Sond appears on the LCD. Then release the ‘PROG’ button. The special functions menu can only be accessed when the heating control is in the normal operating mode (time and date are displayed on the left of the display and the temperature is displayed on the right of the display).
CALC a) Setting the decalcification time (‘CALC CALC’) The valve is completely opened and closed once a week. This prevents deposits from blocking CALC the valve. You can use the special ‘CALC CALC’ function to change the time at which the decalcification cycle is carried out. Sond • Press the ‘PROG’ button until ‘Sond Sond’ is displayed. Then release the ‘PROG’ button. CALC • Use the scroller to select the special ‘CALC CALC’ function. • Confirm this by pressing the ‘PROG’ button.
°C°F b) Selecting the temperature unit (‘°C°F °C°F’) Here you can select whether the temperature is to be displayed in degrees Celsius (°C) or degrees Fahrenheit (°F). Sond • Press the ‘PROG’ button until ‘Sond Sond’ appears on the LCD (for special function). °C°F • Use the scroller to select the special ‘°C°F °C°F’ function. • To confirm your selection, briefly press the ‘PROG’ button. • You can use the scroller to switch between ‘°C’ and ‘°F’. • To confirm your selection, briefly press the ‘PROG’ button.
Proceed as follows to change or set the code: Sond • Press the ‘PROG’ button until ‘Sond Sond’ appears in the LCD. COdE • Use the scroller to select the ‘COdE COdE’ function. • To confirm your selection, briefly press the ‘PROG’ button. The following information is displayed: MO DI MI DO FR SA SO Figure 31 12 6 0 24 18 • Use the scroller to select the first part of the code (a number between ‘000’ and ‘099’) and confirm your selection by briefly pressing the ‘PROG’ button.
Now you need to synchronise the (first) valve operating mechanism (‘001’ on the display) to the new security code. Proceed as follows to carry out this synchronisation: • Remove the battery compartment cover of the (first) valve operating mechanism by sliding it down. • Press the button on the valve operating mechanism for approx. 3 seconds until you hear 3 signal AC tones. The valve operating mechanism is now ready to receive and ‘AC AC’ is displayed.
An A e) Setting the number of valve operating mechanisms (‘An A’) You use this menu item to set the number of radiators (valve operating mechanisms) to be controlled when the heating control is used to control several valve operating mechanisms in one large room, for example. If you install an additional valve operating mechanism, you must ensure that this valve operating mechanism is assigned the same security code as the valve operating mechanisms, which are already installed.
4. The valve operating mechanism acknowledges that it has received the code correctly with a tone sequence. 5. Replace the valve operating mechanism’s battery compartment cover. 6. The valve operating mechanism acknowledges that it has received the first normal radio signal with a signal tone. • Repeat these 6 steps for all the other valve operating mechanisms that are located in the room (‘002’, ‘003’ ... on the display) according to the number of valve operating mechanisms that has been set.
tESt g) Test mode (‘tESt tESt’) You can use this function to check whether all the valve operating mechanisms receive the radio signal correctly. The addressed valve operating mechanisms acknowledge correct reception with an acoustic signal. Use the scroller to select the valve operating mechanisms to be tested. If the large display shows a ‘0’, then all the receivers are tested, otherwise, only the valve operating mechanism assigned to the displayed number is tested.
CEnt i) Connecting to the home radio central unit (‘CEnt CEnt’) You only require this special function, if you want the heating control to work with a new ‘FHZ1000’ central unit or no central unit at all, in other words, you wish to unregister the heating control from the central unit. Radio communication between the heating control and the central unit is also protected by the heating control’s security code. For this purpose the respective heating control is ‘registered’ with the central unit.
FEn j) Querying the status of a door/window contact sensor (‘FEn FEn’) FEn You can use the ‘FEn FEn’ special function menu to request the current status of a ‘FHT80TF-2’ door/window contact sensor. You can also use this menu to newly register or delete door/ window contact sensors. Proceed as follows to access the door/window contact sensor’s menu: Sond • Press the ‘PROG’ button until ‘Sond Sond’ appears on the LCD. FEn • Using the scroller, select the special ‘FEn FEn’ function.
k) Registering a door/window contact sensor Proceed as follows to register a door/window contact sensor with the ‘FHT80B-3’ heating control: • The ‘FHT80B-3’ door/window contact sensor must be properly installed. Sond • Press the ‘PROG’ button until ‘Sond Sond’ appears on the LCD. FEn • Using the scroller, select the special ‘FEn FEn’ function. • To confirm your selection, briefly press the ‘PROG’ button. • Use the scroller again to select the desired memory location.
I) Deleting door/window contact sensors Door/window contact sensors that are no longer required or are no longer in operation should be deleted in order to avoid repeated error messages from being displayed (‘reception failure’). The power consumption also increases as attempts are regularly made to receive signals from the door/window contact sensors. Proceed as follows to delete a door/window contact sensor: Sond • Press the ‘PROG’ button until ‘Sond Sond’ appears on the LCD.
OFFS m) Radiator offset (‘OFFS OFFS’) This setting option is only displayed, if you use more than one valve operating mechanism. If several radiators are controlled by one heating control, it may be that these radiators do not heat up to the same level. The reason for this is that the flow rates of the valves differ greatly, depending on varying or poorly dimensioned radiators.
14. Replacing the batteries a) ‘FHT80B-3’ heating control If the symbol ‘ ’ appears on the LCD, this means that the batteries are low and must be replaced. To replace the batteries, proceed as follows: • Remove the heating control from the wall holder and open the battery compartment cover (slide down). • Remove the batteries from the battery compartment and dispose of them according to the applicable envronmental regulations. See section 18.
• Insert two new Mignon/AA batteries into the valve operating mechanism’s battery compartment, making sure that the polarity is correct. Otherwise you may destroy the valve operating mechanism’s electronic components! C2 C1 C2’, followed • The display shows ‘C1 C1’ followed by a 2-digit number. The display then shows ‘C2 by another 2-digit number (both numbers are the currently stored security code of the valve operating mechanism) . A1 • A signal tone is then generated and ‘A1 A1’ is displayed.
