1. LOCATION OF THE DEVICE

The thermostat of the 

COMPUTHERM 

Q3 RF

 type device can 

be freely moved in your residence. It is reasonable to locate it in 
a room used regularly or for  many hours per day so that it is in 
the direction of natural ventilation in the room but protected from 
drought or extreme heat (e.g. direct sunlight, refrigerator, chimney, 
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,  replace  the  thermostatic 
head  of  the  radiator  valve  with  manual  control  knob  or  adjust  it 
to maximum temperature in the room where the room thermostat 
is to be located, otherwise the thermostatic head may disturb the 
temperature control of the flat.

2. PUTTING THE THERMOSTAT INTO OPERATION,    

    BASIC SETTINGS

To  put  the  thermostat  into  operation, 

detach the rear panel of the thermostat from 
the front panel by loosening the screws at the 
bottom of the cover as shown in the figure.

The  battery  compartment  is  in  the  inner  side  of  the  front 

panel of the housing. Insert 2 AA alkaline batteries (LR6 type) in 
accordance with the diagram in the battery compartment. After the 
batteries  have  been  inserted,  the  display  flashes  the  measured 
room temperature. (If this information fails to appear on the display, 
press the „

RESET

” button with a wooden or plastic stick. To press 

the  button,  do  not  use  any  electrically  conductive  materials  or 
graphite pencil).
