Cooling limit at OT
If the composite outdoor temperature is higher than
the cooling limit, cooling is released. If the
composite outdoor temperature falls at least 0.5°C
below the cooling limit, cooling is locked.
Lock time at end of heating
To avoid a quick start of cooling after termination of
heating, the cooling function is locked for a time
period which can be adjusted with this setting.

920 Summer compensation setpoint increase
In summer the "cooling comfort setpoint" (line 902)
is gradually increased according to the outdoor
temperature. This saves on cooling power and
prevents the differences between the ambient
temperature of the room and the outdoor
temperature being too high.
The resulting "room temperature setpoint" can be
viewed in the Info section.
Summer compensation start at OT
Summer compensation starts to be active from the
outdoor temperature defined here. If the outdoor
temperature continues to rise, the comfort setpoint
will be gradually increased.

The lock time starts when there is no valid heating
demand from heating circuit 1. Heating demands
from heating circuits 2 or P are ignored.
Information:
Switching off and switching on again the mode
selection key causes the lock time to be interrupted.
Summer compensation end at OT
At this outdoor temperature the summer
compensation reaches its peak efficiency (line
920). If the outdoor temperature continues to rise, it
will no longer influence the comfort setpoint.

This setting defines the highest value to which the
comfort setpoint can be increased.
