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
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.
20 °C
OFF, set value of system frost protection to 40 °C
