5.4.1 Electricity supplier lock
Some electricity supply companies (ESCs) are gran-
ting discounted electricity rates for heat pumps. For
this they reserve the right to interrupt the delivery of
electricity at certain times.
Two ways for the controller to recognise these sche-
duled power cuts as being proper (and thus not inter-
preted as an operating fault):
–
By the electrical ESC-lock signal (in case of doubt
ask your electrician)
–
By recording on the
ESC lock
screen
If the ESC's electrical lock signal is not available,
enter the blocking times announced by the ESC in
this screen:

!
CAUTION
Before activating the blocking
times, the screed drying must be completed.
Failure to do so may damage the screed.
5.4.2 Night-time reduction
This function is used for possible noise reduction
during the night-time hours. This is done by limiting
the fan

and/or compressor speed

Please note that the power restriction of the
heat pump may increase the consumption
during auxiliary heating (e.g. electric heating
element).
!
CAUTION
- Attention: Before activating the
reduction, the screed drying must be com-
pleted.
5.4.3 Blocking times for electric heating ele-
ment/heat pump
Function: The electric heating element and/or the
heat pump can be locked in desired time ranges (e.g.
to give priority to other energy source such as solar
system, log wood boiler, ...).
