Installation

Battery installation
First, remove the rear cover from the room unit. Do this by carefully pulling the cover from the top and bottom of the cover and pulling it outwards. Then insert two AA (LR6) 1.5V batteries the correct polarity. After insert the unit’s back cover.

Installation of the room unit
You can place the thermostat on the wall in the desired room or on the attached bracket, with which you can have the unit anywhere in the room. Perform the wall mounting by removing the back cover and marking where you will drill holes for it. Then, screw the cover into the designated, marked place and “attach” the room unit. Place the thermostat in a location where it is not directly exposed to a heat source or to sunlight (example in the picture). The receiver should not be mounted directly on the metal surface.In the case of using the bracket, just slide the unit into the bracket.

Advice on thermostat installation and position in the room
In any case of the thermostat installation (on wall or portable), be careful not put it near sources of hot or cold air, direct sunlight, draught or other types of temperature influences. Also, make sure that the thermostat is placed at least 30cm away from metal parts and 1 meter from other electrical devices. If you mount the thermostat on a wall, the optimum height for mounting is 150cm and at least 20cm away from the door, windows, cupboards and similar objects. Also, install the thermostat on the inside wall of the house. If you don’t follow these recommendations, it can happen that the thermostat will not function correctly. Because of signal interference (electrical sources, metal parts, …) or due to incorrect reading of the temperature (drafts, sun, cold or the hot spot, …).
