COMPUTHERM Q5RF Multi Zone Wireless Digital Room Thermostat Instruction Manual
With factory default settings the jumper is located on the central and
uppermost pins, in which case the display shows the currently meas-
ured room temperature value, while the notice “ROOM” appears in the
bottom right corner of the display. In this case, the adjusted tempera-
ture is visible only during the adjustment process, for approximately 6
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 tem-
perature and the adjusted temperature for 3-3 seconds, respectively.
In this mode, the notices “ROOM” and “SET” are alternately shown
under the currently displayed temperature in the bottom right corner of
the display, indicating whether the display shows the room temperature
or the adjusted temperature value.
3.2 Selecting the Switching Sensitivity (Accuracy)
The switching sensitivity of the thermostat can be selected or adjust-
ed by the central jumper which detemines how much the thermostat
switches the connected appliance on / off below / above the set tem-
perature.
With factory default settings the jumper is located on the central
and uppermost pins, resulting in a switching sensitivity of ±0.2 °C.
It can be modified to ±0.1 °C by relocating the jumper onto the
- 8 -
bottommost and central pins. A smaller switching sensitivity re-
sults in steadier room temperature and therefore in higher comfort.
The heat loss of the room (building) does not depend on the switching
sensitivity.
If higher comfort is needed, the switching sensitivity should be set so
that it provides a steadier room temperature. On the other hand, please
also take into account that the boiler should not switch on and off mul-
tiple times in an hour’s time except at low outside temperatures (e.g.
-10 °C), since the frequent on and off switches of the boiler reduce
its efficiency and hence increases the gas consumption. We recom-
mend using the ±0.1 °C switching sensitivity for heating systems with
high thermal inertia (e.g. underfloor heating), and the ±0.2 °C switching
sensitivity (factory default setting) for heating systems with low thermal
inertia (e.g. flat panel radiators).
You can read more about switching sensitivity in Chapter 5.
3.3 Switching between the Heating and Cooling Mode
The heating or the cooling mode of the thermostat can be
selected by the right jumper. With factory default settings the
jumper is located on the central and uppermost pins, which
selects the heating mode. By relocating the jumper onto the
- 9 -
bottommost and central pins, the cooling mode can be selected.
The output terminals of the receiver unit NO - COM and the zone
outputs are turned on below the set temperature in heating
mode, and they are turned off above the set temperature in
cooling mode (taking the switching sensitivity into account).
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. When you adjust the potentiometer clockwise then
the displayed temperature will be lower than that measured
initially, and when you adjust it anticlockwise the displayed
temperature will be higher than that. The displayed temperature
can be adjusted within a range of approx. ±4 °C.
Correction of the displayed temperature takes place a few
seconds after the adjustment.
ATTENTION! If the modification of the basic settings was done
after inserting the batteries and the modifications did not take ef-
fect, please press the “RESET” button located on the main panel
of the thermostat.
