Undoing deactivation
Deactivation is undone when the averaged and current outside temperature exceeds the set value by 1 K.
The summer deactivation function is undone:
•In case of an outside sensor defect
•In case frost protection is active
NOTE During deactivation phases (standby mode, manual summer operation, summer deactivation) lasting longer than 24 hours all pumps are switched on for approx. 20 s and the mixers are temporarily opened during this time to protect against blocking by corrosion.
In connection with a second outside sensor, the current averaged outside temperature is accepted for summer deactivation if the average value of both sensors is specified during outside sensor assignment.
Active summer deactivation is represented by a beach umbrella symbol in the basic display.
Only active in the AUTOMATIC operating mode.
