# Code Description
[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.
▪ –5°C~5°C, step 0.5°C
[1.7] [2-09] Room sensor offset (external room
sensor option): ONLY applicable if the
external room sensor option is installed
and configured.

8.4.3 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 43 .
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 Description
[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 page 44 .
Cooling schedule
You can set the main zone cooling temperature using the schedule
screen. For more information about this screen, see
"8.3.8 Schedule
screen: Example" on page 44 .
Setpoint mode
In Fixed mode, the desired leaving water temperature does NOT
depend on the outdoor ambient temperature.
In WD heating, fixed cooling mode, the desired leaving water
temperature:
▪ depends on the outdoor ambient temperature for heating
▪ does NOT depend on the outdoor ambient temperature for cooling
In Weather dependent mode, the desired leaving water temperature
depends on the outdoor ambient temperature.
# Code Description
[2.4] N/A Setpoint mode
▪ 0: Fixed
▪ 1: WD heating, fixed cooling
▪ 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.
