Undoing deactivation

Operation	SDC / DHC

Quick increase in outside temperature

If the averaged outside temperature is below the set value and the current outside temperature is 2 K above the set value, heating operation is interrupted.

Slow increase in outside temperature

Deactivation is also initiated when the averaged and current outside temperature exceeds the set value.

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.

Factory setting 20 °C

Setting range OFF, set value of system frost protection to 40 °C
