33.1 DHW circulation pump
33.1.1 Return temperature
To be able to use this operating program, you need auxil-
iary module A or B.
The DHW circulation pump is switched on when the return
temperature is lower than the current DHW temperature
target value minus two times the current switch-ON dif-
ferential.
Note
If the return temperature sensor has a fault, this
function is not used. However, the time interval
circuit remains active.
The DHW circulation pump runs until one of the following
occurs:
► The return temperature is greater than the current
DHW temperature target value minus the current
switch-ON differential:
1 Set target DHW temperature
2 Set switching differential
3 Current DHW temperature at the DHW temperature
sensor
4 Heat demand
5 DHW circulation pump switched on
6 DHW circulation pump switched off
► The runtime of the DHW circulation pump has been
reached:
1 Set target DHW temperature
2 Set switching differential
3 Current DHW temperature at the DHW temperature
sensor
4 Heat demand
5 DHW circulation pump switched off
6 DHW circulation pump runtime (DHW circulation
pump switched on)
7 DHW circulation pump standby time (DHW circulation
pump switched off)
► DHW charging will take place.
