Carry out an operating display adjustment (High Flow balance, if required)
The High Flow balance establishes the
existing (higher) flow rate as nominal
flow rate.
Note
The High Flow balance can shift the
switching point of the flow switch.
1. Start the appliance with the existing
flow rate.
2. Hold down for around 5 s, until
LED "9" flashes.
3. Release .
Checking the electronic frost stat, type AC1-2W
The electronic frost stat monitors the
refrigerant temperature on entry into the
compressor.
Note
The frost stat switching points are fac-
tory-set.
Adjusting these switching points is pos-
sible in special cases, for example if the
flow temperature of the primary circuit
(groundwater inlet into the heat pump) is
subject to severe fluctuations.
