3.9 Blocking protection for heating
circuit pump:
The heating circuit pump is switched on
every day at 12 o´clock for 30 seconds.
Thus, pump blocking is avoided. This func­
tion will only be suppressed if the set fl ow
temperature is reached, the fl ow sensor is
damaged or the DHW priority function is
active.

3.10 Antifreeze function:

If the temperature at the fl ow sensor falls
below 8 °C, the heating circuit is activated.
If the fl ow temperature reaches 10 °C, the
heating circuit is deactivated.

Operation and function

Connect the SKSCEM1 heating circuit
module(s) to the SKSC3+ main control­
ler via the VBus. Activate the heating cir­
cuit module(s) in the Options menu of the
controller. All adjustment and display val­
ues are listed in the corresponding menu
(heating circuit 1,2,3)
ATTENTION: It is only possible to connect
the same type/software version of heating
circuit modules to a SKSC controller!

3.11 Store afterheating (Differential
control):
For the afterheating of the store, the dif­
ference between the calculated fl ow set
temperature and one or two reference
sensors at the store/buffer is measured. If
the difference between both temperatures
is too small, the afterheating is activated.
The afterheating switches off when the dif­
ference between store and fl ow set tem-
perature is high enough.
