As an option you can plug in a room thermostat to the controller. Direct plug in of a room thermostat optimizes the
operational time of the circulation pump and even the supply flow temperature depending on the conditions in the
main room.
5.3.1. Standard room thermostat, wired type
If a wired type of a standard room thermostat is plugged in and the preset room temerature is
reached the circulation pump switches off.
If no room thermostat is connected (the cable bridge is left in place), then the circulation pump
switches off if within 30 minutes the controller has not initiated any change in the flow temperature.
5.3.2. RF room thermostat
If a radio frequency room thermostat is plugged in, the flow temperature calculated on the basis of outdoor
temperature and the heating curve (= flow temperature preset value) is optimized depending on the main
room temperature. The offset value is calculated in the following way:
Adjustment = preset value of supplied tempe (room temperature - actual value
) х offset
(offset:

System parameters:
value for adjustment of flow temperature)
Example 1:
preset value of flow temperature = 35 °C; room temperature: preset value = 21 °C,
actual value = 19 °C; offset = 1,5
Estimation 1:
35 °C + (21 °C – 19 °C) × 1,5 K >> flow temperature increased by 3,0 K to 38 °C
Example 2:
preset value of flow temperature = 35 °C; room temperature: preset value = 21 °C,
actual value = 22 °C; offset = 1,5
Estimation 2:
35 °C + (21 °C – 22 °C) × 1,5 K >> flow temperature decreased by 1,5 K to 33,5 °C
Radio alarm:
If the Controller is activated by the RF thermostat and there is no transmission of radio
signals for more than 2 hours, an alarm will be activated.
7. To stop the alarm, keep the
(OK)
button pressed for about 10 seconds.
8. Check the batteries of the RF thermostat. Please replace them if exhausted.
9. Check the position in which the antenna was installed. It must be installed in vertical position.
Installation in or on a metal body can abate the power of radio transmission. Minimize the distance
to the RF thermostat.

Only RF thermostats from the WFHT-RF series or the MILUX-RF
series can be used together with an active antenna.
