The brine circuit should be fitted with a pressure
expansion vessel. If there is a level vessel, this should
be replaced. The brine side should be pressu rised to
at least 0.5 bar.
The pressure expansion vessel should be dimen-
sioned as set out in the diagram, to prevent operat-
ing disturbances. The pressure expansion vessel cov-
ers the temperature range from -10 °C to +20 °C at a
pre-pressure of 0.5 bar and the safety valve’s opening
pressure 3 bar.

For HTF in hotter than -5 °C, limiting of max conden-
ser out 65 °C and max condenser in 58 °C.
For HTF in colder than -5 °C, max condenser out and
max condenser in lowers automatically, according to
diagram, additional heat maintains desired supply
temperature.
For HTF in lower than -8 °C, the compressor stops and
the desired supply temperature is only maintained by
additional heat.
