Room temperature offset
ONLY applicable in case of room thermostat control. You can calibrate the room
temperature sensor. It is possible to give an offset to the room thermistor value
measured by the user interface. The settings can be used to compensate for
situations where the user interface cannot be installed on the ideal installation
location.
# Code Description
Room temp. offset : Offset on the actual room temperature measured on the
user interface sensor.
[A.3.2.2] [2-0A] –5°C~5°C, step 0.5°C
Ext. room sensor offset : ONLY applicable if the external room sensor
option is installed and configured (see [C-08])
[A.3.2.3] [2-09] –5°C~5°C, step 0.5°C
Room frost protection
Room frost protection prevents the room from getting too cold. This setting
behaves differently depending on the set unit control method ([C‑07]). Perform
actions according to the table below:
Unit control method ([C‑07]) Room frost protection
Room thermostat control ([C‑07]=2) Allow for the room thermostat to take
care of room frost protection:
▪ Set [2‑06] to "1"
▪ Set the room antifrost temperature
([2‑05]).
External room thermostat control
([C‑07]=1) Allow for the external room thermostat
to take care of room frost protection:
▪ Turn ON the leaving water
temperature home page.
Leaving water temperature control
([C‑07]=0) Room frost protection is NOT
guaranteed.
NOTICE
Room frost protection. Even if you turn OFF the leaving water temperature (main +
additional) control via the home pages ( LWT main + LWT add ), room frost
protection –if enabled– will remain active.
INFORMATION
If a U4 error occurs, room frost protection is NOT guaranteed.
See the sections below for detailed information on room frost protection in
relation to the applicable unit control method.
[C‑07]=2: room thermostat control
Under room thermostat control, room frost protection is guaranteed, even if the
room temperature home page is OFF on the user interface. When room frost
protection ([2‑06]) is enabled and the room temperature drops below the room
antifrost temperature ([2‑05]), the unit will supply leaving water to the heat
emitters to heat up the room again.
