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
"5.7 Setting up an external temperature sensor" on page 21

Room sensor offset (user interface used
as room thermostat): Offset on the actual
room temperature measured on the user
interface used as room thermostat.

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.

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.

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.
