The portability of the thermostat offers the following advantages:

no need to lay a cable, which is especially advantageous when 

 

old buildings are being modernized

optimal location of the device can be selected during operation

 

it is also advantageous when you intend to locate the thermostat 

 

in different rooms in the course of the day (e.g. in the living 

room during the day but in the bedroom at night)

The  effective  range  of  the  transmitter  incorporated  in  the 

thermostat  is  approximately  50  m  in  open  terrain.  This  distance 
may  become  considerably  shorter  within  a  building,  especially 
when a metal structure or a reinforced concrete wall stands in the 
way of radio waves.

The switching sensitivity of the thermostat is ± 0.2°C (± 0.3°C). 

This means the difference between the adjusted temperature and 
the actual temperature measured during the switching process. For 
example, if the factory default setting is 20°C on the thermostat, 
then  the  device  switches  the  boiler  on  at  19.8°C  or  below,  and 
switches it off at 20.2°C or above.

This wireless (radio-frequency) thermostat can also be extended 

with the 

COMPUTHERM

 

Q1 RX

 socket if needed, with which the 

thermostat is able to control boilers or any other electrical devices 
operating on 230 V (50Hz; max. 10A)  (e.g. fan heaters, pumps, 
zone valves, etc.) according to the room temperature. (For more
