• The product is not a toy. Keep the product away from children. Therefore, be particularly careful when children are present. • The product must not be exposed to extreme temperatures, strong vibration, strong moisture or strong mechanical strain. The product must not become damp or wet. Contact with moisture must be avoided under all circumstances.
• The following unfavourable conditions are to be avoided at the place of use and during transport: - Dust or flammable gases, fumes or solvents - Strong vibration, impact or blows • Handle the product with care. It can be damaged by impact, blows or when dropped even from a low height. • If it can be assumed that safe operation is no longer possible, the device must be turned off and precautions are to be taken to ensure that it is not used unintentionally.
• In commercial institutions, the accident prevention regulations of the Employer’s Liability Insurance Association for Electrical Systems and Operating Materials are to be observed. • If you have questions which remain unanswered by these operating instructions, please contact us or another expert. b) Batteries • Batteries have no place in the hands of children. • Do not leave any batteries lying around openly. There is a risk of batteries being swallowed by children or pets.
• If not used for a longer period (e.g. in case of storage), remove the inserted batteries. If batteries are too old, they may leak and cause damage to the product, which leads to the cancellation of the warranty/guarantee! Read the “Disposal” chapter for instructions on environmentally sustainable disposal of batteries.
7. Installation The room thermostat must only be installed by a qualified specialist. Installation must only be performed according to the applicable local provisions. The room thermostat must not be installed near any windows, doors, heat sources or ventilation openings. Also avoid installation in locations where the device is exposed to direct sunlight. This may falsify the measured room temperature. Keep a distance of approx. 1.5 m for this.
Check the mains supply line for voltage-freeness. Ensure that no present electrical or water lines are damaged during installation. The same applies, if only low voltage is to be supplied through the relay, since this may cause short circuit at installation! Remove the battery holder at the bottom of the device. Turn the housing screw at the bottom of the controller out only until the upper shell of the room thermostat can be removed. Do not turn the housing screw out entirely.
The installed relay is potential-free. The connection example shows the connection to mains voltage 230 V/ AC. Observe the maximum contact resilience; see chapter “Technical Data” and the operating instructions of the device that is to be controlled via the room thermostat, on how to set up the circuits. 1 = Normally open contact (NO) 2 = COM (Common) 3 = Normally closed contact (NC) L 230 V/AC, 50-60 Hz E.g.
Push the upper shell onto the base plate (figure 2). Make sure that the supply lines are not crushed or damaged by this. The upper shell is now attached to the base plate again with the housing screw (figure 3). The room thermostat must only be operated with the correctly attached and screwed-on upper shell.
8. Inserting or replacing the batteries • Pull the battery holder from the bottom of the device. • Insert the two batteries of type AAA (Micro) in the correct polarity. Observe the marking in the battery compartment holder. • Return the battery holder to the room thermostat. • Use only alkaline batteries. se only batteries of the specified type. Use alkaline U batteries for the longest operating duration. The product is only approved for operation with 2x 1.5 V AAA-batteries (Micro).
9. Commissioning and operation Observe Chapter “Safety information”! PROGRAMME Mode AUTO Mode Time/temperature display Manual mode Frost protection function Icon Display Celsius Display AM / PM Symbols for switching times Symbol for time setting Display off Display SET ECONOMIC temperature Display calibration LOCK function Heating/consumer on Battery display a) Switching on/off Push the button OK to switch on the room thermostat.
b) Selection of the operating function Switch on the room thermostat. Push the button OK repeatedly until the desired operating function (manual mode; frost protection function; AUTO mode; PROGRAMME mode) is displayed. c) Manual operation Manual operation serves constant increase or reduction of the room temperature. In manual mode, the symbol is displayed. The factory setting for manual mode is 20 °C. The temperature value set in the factory can be changed. For this, push the button plus + or -.
d) AUTO mode The following values are set ex works for AUTO mode. 00:00——06:00 Temperature setting: 18 °C 06:00——08:00 Temperature setting: 20 °C 08:00——18:00 Temperature setting: 16 °C 18:00——22:00 Temperature setting: 20 °C 22:00——24:00 Temperature setting: 18 °C In AUTO mode, the symbol “AUTO” is displayed. The temperature value set ex works can be changed for the current heating or reduction phase. Briefly push the plus + or minus - button.
e) PROGRAMME mode Set the switching times and temperatures as described in item “PROGRAMME setting”.Then switch the room thermostat to PROGRAMME mode. The symbol “AUTO PROG” is displayed. The programmed temperature value can be changed manually for the current heating or reduction phase. Briefly push the plus + or minus - button. The temperature display will change from the current room temperature to the set temperature.
f) Frost protection function When the frost protection function is active, the room thermostat will prevent the room temperature to drop below 5 °C. The frost protection function thus prevents freezing of liquid-based heatings and pipes. The frost protection temperature is fixed at 5 °C in the factory and cannot be changed. When the thermostat is in the frost protection function, the symbol will be displayed.
10. Settings The thermostat must be on. Push the buttons SET and OK at the same time to get to the setting mode. The relay switches off in setting mode. Change the values with the buttons “+” and “-”. Keep the respective button pressed for quick adjustment. If you do not push any button for approx. 60 seconds, the settings made until then are saved and setting mode is left. Push the OK button to save the setting and to leave the setting mode.
The settings are only applied with the next temperature measurement of the thermostat. This may take a while. b) Time setting The time is set in 12-hour format (midnight to noon = AM / noon to midnight = PM).
d) PROGRAMME setting Set the desired start, end times and temperatures for the programme mode here. The connected consumer is switched on and off by remote control after this time. Two switching periods can be programmed.
11. Setup To switch to the setup settings, the thermostat must be in the position OFF. or Keep SET and OK buttons pushed for 5 seconds To set the parameters or Switch to the next setting To set the parameters Push the OK button to confirm and to switch to manual mode Change the values with the buttons “+” and “-”. Keep the respective button pressed for quick adjustment. If you do not push any button for approx. 60 seconds, the settings made until then are saved and setting mode is left.
