• Summer compensation
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 tem-
perature 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 out-
door temperature defined here. If the outdoor temperature continues to rise, the comfort setpoint
will be gradually increased.
– 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.
– Summer compensation setpoint increase: This setting defines the highest value to which the
comfort setpoint can be increased.
