6.3.2 Comfort function
The protection against limescale is deactivated when the heat exchanger is always warm.
Do not activate the comfort function when there is an increased risk of limescale.
The primary inlet to the heat exchanger can be warmed up in order to speed up the start of the
module. To do that, the primary pump is actuated depending on the flow temperature.
The comfort function controls the operation of the primary pump when there is no withdrawal
and circulation. After starting the pump, the comfort function is locked for a waiting time
(time-ComfBreak).
It is possible to limit the waiting time to a specific time window using a weekly timer
(timer same as for circulation). The flow sensor serves as the primary sensor T-FL (S1).
The function can be activated or deactivated (default setting = OFF).
Comfort break, min = 1 min
Comfort break, max = 60 min
Default setting = 10 min
