If...
Space heating/cooling is ON,
the external room thermostat is
"Thermo OFF", the operation
mode is "heating" and the
outdoor temperature drops below
4°C
Room thermostat control ([C‑07]=2)
During room thermostat control, room frost protection is guaranteed
if it is enabled. When room frost protection [2‑06] is activated 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.
# Code
[1.4.1] [2-06] Activation:
▪ 0 No: Antifrost functionality is OFF.
▪ 1 Yes: Antifrost functionality is on.
[1.4.2] [2-05] Room setpoint 4°C~16°C
INFORMATION
When the user interface used as room thermostat is
disconnected (due to miswiring, damage of the cable), then
room frost protection is NOT guaranteed.
NOTICE
If Emergency is set to Manual ([9.5]=0), and the unit is
triggered to start emergency operation, the unit will stop
and need to be recovered manually via the user interface.
To recover operation manually, go to the Malfunctioning
main menu screen, where the user interface will then ask
you to confirm emergency operation before starting.
Room frost protection is active even if the user does NOT
confirm emergency operation.
Setpoint range
ONLY applicable in room thermostat control. To save energy by
preventing overheating the room, you can limit the range of the room
temperature for heating.
NOTICE
When adjusting the room temperature ranges, all desired
room temperatures are also adjusted to guarantee they are
between the limits.
# Code
[1.5.1] [3-07] Heating minimum
[1.5.2] [3-06] Heating maximum
Room sensor offset
ONLY applicable in case of room thermostat control. You can
calibrate the (external) room temperature sensor. It is possible to
give an offset to the room thermistor value measured by the user
interface used as room thermostat or by the external room sensor.
The settings can be used to compensate for situations where the
user interface used as room thermostat or the external room sensor
CANNOT be installed on the ideal installation location (see
"5.6 Setting up an external temperature sensor" on
# Code
[1.6] [2-0A] Room sensor offset (user interface
used as room thermostat): Offset on the
actual room temperature measured on
the user interface used as room
thermostat.

Main zone

Setpoint screen
You can set the leaving water temperature for the main zone using
the setpoint screen. For more information about how to do this, see
"8.3.5 Setpoint screen" on page 47.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
▪ In Weather dependent LWT setpoint mode, the scheduled
actions consist of desired shift actions, either preset or custom.
# Code
[2.1] N/A Schedule
▪ 0: No
▪ 1: Yes
Heating schedule
You can set the main zone heating temperature schedule using the
schedule screen. For more information about this screen, see
"8.3.8 Schedule screen: Example" on
Setpoint mode
In Fixed mode, the desired leaving water temperature does NOT
depend on the outdoor ambient temperature.
In Weather dependent mode, the desired leaving water
temperature depends on the outdoor ambient temperature.
# Code
Setpoint mode
[2.4] N/A
▪ 0: Fixed
▪ 2: Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user has the possibility to shift the
water temperature up or down by a maximum of 10°C.
Heating WD curve
