INSTALLATION AND LOCATION
Install the thermostat at a suitable place where its operation cannot be affected by direct flow
of hot air from the heater, sunshine or other disturbing effects. Neither install it on an external
wall. The installation height should be approx. 1.5 m above the floor. Place the thermostat in
the “reference room”, such as the living room (the heating source will switch according to the
temperature in this room).
The installation must only be done by a properly qualified person!
Before installation, disconnect the power supply!
1) Switch off the main circuit breaker.
2) Loosen the locking screw and remove the front part of the thermostat with the
electronics (Fig. 1).
3) Fix the back part of the thermostat to the wall (Fig. 2).
4) Connect the wires to the terminal board; take heed to proper tightening of the
terminals.
5) Put on the front part of the thermostat with LCD and ensure the thermostat with the
locking screw against splitting.
6) Switch on the main circuit breaker. If everything is OK, the LCD shows the current
temperature.
7) Set the thermostat parameters and the required temperature program according to the
instructions.
