A6:35 pump will stop and the mixer will be
closed at a variable value, adjusta-
ble between 5 and 35 °C plus 1 °C.
The base value is the adjusted out-
side temperature. This value is
based on the actual outside temper-
ature and a time constant, which
takes the cooling down of an aver-
age building into consideration.
