Instruction Manual TOWERSTAT RF Selectable Volt Free Warning – Please read this manual prior to installation or use Shock Hazard This unit must be installed by a competent person, in accordance with BS 7671 (the IEE Wiring Regulations), or other relevant national regulations and codes of good practice. Always isolate the AC Mains supply before removing the unit from the wall box.
INTRODUCTION This thermostat can replace most common residential thermostats and is designed to be used with electric, gas or oil heating control systems or cooling systems. Unlike conventional thermostat devices, this control is a new type of thermostat which separates the functions into two units. The Receiver serves for wiring connections and heat/cool on/off control The Transmitter serves as the user interface and for temperature sensing / control.

Features : Several useful functions and operating modes have been incorporated to adapt to a variety of customer needs, as well as all the features associated with a state of the art programmable thermostat. Transmitter: Can be placed anywhere in the home to detect and control the temperature of an area of the user’s choice. Not limited by power control wiring locations. Linked with the Receiver via RF. Control distance 100m in free space.
Receiver Linked with Transmitter via RF Power rating up to 230VAC 16A resistive Powered by line voltage only. No battery required. Two l.e.d.
INSTALLATION OF RECEIVER Caution: 1. It is recommended that this device is installed by a qualified electrician 2. The appliance can only be mounted indoors and in areas free from any water or moisture 3. A suitable fuse with a rating not exceeding 13A should be in the power line 4. Wiring must conform to I.E.E. regulations RF Address Code Setting If there is another user nearby, e.g. in the next dwelling, your Receiver may be operated in error by their Transmitter.
2. 3. To change the address code of the Transmitter, open the Transmitter housing (refer to battery replacement section to open housing). Remove one or more of the jumper links as shown in the illustration below. Remove one or more of the jumper caps to adjust the RF code Address code # 1 – 5, from left to right Ensure the sequence matches the settings of the dip switches on the receiver Caution: 1. Address code of the Transmitter must be the same as address code of Receiver.
Removing your old thermostat Caution : to avoid electric shock, isolate the power of the heating / cooling system at the main consumer unit in your home. Read the following instructions carefully before disconnecting the wires. 1. Turn off your old thermostat 2. Remove the cover from the old thermostat 3. Unscrew the old thermostat from the wall plate 4. Now find the screws attaching the wall plate to the wall, and remove them. You should now be able to pull the wall plate a small distance from the wall.
Mounting the Receiver onto the optional wall box: 1. Remove the front cover of the Receiver 2. Mark the holes position for the wall box 3. Drill two holes and insert the wall plugs until they are flush with the wall surface 4. Pull the wires into the wall box and fasten the wall box onto the wall 5. Connect the wires (see wiring diagram) 6. Securely fasten the Receiver to the wall box with the two machine screws provided 7. Replace the front cover and installation is complete.
Setting of Transmitter Heating / Cooling Selection To adjust the Transmitter for heating or cooling function, also for code changes, and to insert / remove batteries, the Transmitter back housing must be removed: Once the back housing is removed, inside the Transmitter you can find a three-position dip switch. The three switches control the temperature span and set the output for heating or cooling function.
Battery installation Your thermostat uses two ‘AA’ size batteries to operate. To power-up the unit, insert two ‘AA’ batteries into the battery compartment of the front housing. When power is applied for the first time, the display should show time and the day as well as the room temperature. Press the RESET button after insertion of batteries (use a fine instrument such as a straightened paper clip to gently push the RESET button.
Setting the clock (refer to Transmitter layout, p.1) 1. Press the SET TIME button to clear all digits except the day indicator the time display. The day indicator is flashing. 2. While day indicator is flashing, press UP or DOWN button to change the day (Day 1 = Monday) 3. Press the SET TIME button again, the hour digits flash. Now change the hour by pressing the UP or DOWN button. Press and hold the UP or DOWN buttons to speed up the adjustment rate. 4.
3. Press the SET TEMPERATURE button again to return to normal operation mode. 4. The unit will return to normal operation mode if no button is pressed for 10 seconds 5. The default setting of comfortable mode is 210C for heater mode and 230C for cooler mode. And the economic mode is 100C for heater mode and 260C for cooler mode.
2. Scroll through the pre-set program options with the UP or DOWN buttons – these programs can be selected, but they cannot be altered. Use one of the programs if they are suitable for your requirement, or scroll to one of P7, P8 or P9. These three program positions can be user-adjusted to your requirement. 3.
4. If you wish to set your own programme (using any of P7, P8 or P9) select one of those program numbers and press the SET PROGRAM button again. 5. Reading from the top, the display will show your day selection, the hour (starting at 0 = midnight), the sun symbol, the programme number, and a full line of blocks along the bottom of the screen. You can now set your own programme, in one-hour blocks, defining when you require comfort or economic temperature. 6.
Testing the RF transmission range 1. Ensure the receiver is correctly wired to the output, and that it has a mains supply (indicated by a continuous red LED at the receiver) 2. The transmitter display shows the current actual temperature. Press the UP button until the set temperature is higher than the actual temperature. 3. After a few seconds the heater/cooler on icon is shown – it appears as a rotating symbol above the P number. 4. Check the green LED on the receiver. It should be On. 5.
Overriding the set temperature 1. During normal operating mode, press the UP or DOWN arrow buttons to adjust the set temperature point to the desired value. 2. After 10 seconds the unit will revert to normal operating mode, but using the new adjusted temperature as the set point. The hand symbol will be shown in the display. 3. The temporary override will self-reset with the next programmed change of temperature. Alternatively revert to automatic mode by pressing the COMF/ECON button.
recommended to turn the power switch to the Off position. BATTERY REPLACEMENT The batteries should be replaced as soon as the battery-low symbol is showing in the display. There is a short capacitive memory which retains the display and programme for one minute to allow for the exchange of batteries. 1. Turn off the receiver. 2. Remove the back housing and stand of the Transmitter. 3. Replace the old batteries with 2 good quality AA alkaline batteries. 4. Replace the back housing and stand. 5.
