etc). Its optimal location is 1.5 m above floor level. It can be placed on its own stand or can be mounted on a wall. IMPORTANT WARNING! If the radiator valves in your flat are equipped with a thermostatic head, adjust it to maximum temperature or replace the thermostatic head of the radiator valve with a manual control knob in the room where the room thermostat is to be located, otherwise the thermo- static head may disturb the temperature control of the flat. - Page 6 room temperature value, while the notice “ROOM” appears in the bottom right corner of the display. In this case, the adjusted temperature is visible only during the adjustment process, for approximately 7 seconds after the last button has been pushed. By relocating the plug onto the bottommost and central pins the displayed temperature can be modified so that the display alternately shows the current room temperature and the adjusted temperature for 4...

„A/C” (cooling) in the bottom left corner of the display, according to the selected mode. 3.4 Calibration of the thermometer of the thermostat You can calibrate the thermometer of the appliance (to correct measured temperature). To this end all you have to do is change the position of the orange-colored potentiometer by a Phillips screwdriver. - Page 8 • Move the switch according to the temperature you would like to change (economy ( w ) or comfort ( ☼ )). • Press the button, after which the no- tice “ROOM” disappears, the notice “SET” (adjusted value) appears in the bottom right corner of the display. Meanwhile, the temperature value shown on the display switches from room tem- perature to the default temperature (18.0 °C/20.0 °C) or to the last set temperature (this temperature is blinking on the display).

6. BATTERY REPLACEMENT The average lifetime of the batteries is 1 year. The icon alternately replacing the temperature value on the display indicates low battery voltage. Replace the batteries whenever the icon indicating low battery voltage appears on the display (see Section 2). After battery replacement, the desired temperature should be adjusted again, because during the battery replacement the thermostat is reset to factory default settings. - Page 10 The receiver unit controls the boiler or air conditioner through a potential- free relay whose connection points are: NO and COM. Connect the two connection points of the heating or cooling equipment to be controlled to terminals NO and COM, i.e. to the normally open terminals of the relay. These connection points become closed following the heating/cooling command of any thermostat.
