10.1.2.1. Nighttime
cooling
Activate the function in the menu option:
Main index > Configuration > Configuration 2 > Night
cooling
With nighttime cooling, the building is cooled at night using
the cool outdoor air without any extra energy being added.
Nighttime cooling is activated under the following
circumstances:
•
The outdoor air temperature is higher than the limit set:
Outdoor temp. > Min outdoor temp.
•
The outdoor air temperature is lower than the difference
between room temperature and switch-on delta:
Outdoor temp. < Room temp. – Delta
•
The room/extract air temperature is higher than the total
of the room setpoint and hysteresis: Room temp. >
Room se Hysteresis.
Nighttime cooling is deactivated under the following
circumstances:
•
Other start of unit
or
•
Min operating time has been passed
and
•
The outdoor air temperature is lower than the difference
between room temperature and switch-off delta:
Outdoor temp. > Room temp. – 1,
or
•
The room temperature is lower than or equal to the
room setpoint: Room temp. <= Room setpoint

10.1.2.2. Support
operation
Activate the function in the menu option:
Main index > Configuration > Configuration 2 >
Support operation
Nighttime support operation prevents the building from being
cooled or heated too much. This is regulated via a separate
setpoint for heating and cooling. Heating and cooling can be
activated separately.
The function can be implemented using an extract air sensor
if there is no room sensor. However, configuration with the extract
air sensor that holds the highest value should not normally be
used as the support operation can then only start once.
Cooling requirements
Nighttime support operation for cooling requirements is
activated when the following preconditions are met:
•
Room temp. > Start cooling, and the min restart time has
been passed
Switch-off is activated when:
•
Room temp. < Start cooling – Hysteresis
Heating requirements
Nighttime support operation for heating requirements is
activated when the following preconditions are met:
•
Room temp. < Start heating, and the min restart time has
been passed
Switch-off for heating requirements is activated when:
•
Room temp. > Setpoint for h Hysteresis

10.1.2.3. Boost
(optimisation)
Activate the function in the menu option:
Main index > Configuration > Configuration 2 > Boost
Optimised start ensures a comfortable room temperature
when the system is switched on normally. This is regulated
via a separate setpoint for heating and cooling.
