NOTE:
Speed regulation of the domestic hot water pump is independent of the internal pump.
1.6. Superheat Set Limit
For inlet water temperature > 30 °C (>86°F) the superheating is managed by 3-way bypass valve
in combination to specific software improvements. The High Inlet Temperature (HIT)
Function limits the superheat value with the use of the bypass valve, keeping in
consideration both the compressor oil temperature and the compressor discharge temperature.
In order to optimize the cycle efficiency and at the same time avoid too high temperatures to the
compressor, the target superheat value is not constant, but will be adjusted according to the
compressor discharge temperature and compressor oil temperature.
This superheat limit should not be changed by a user except under direction from the
manufacturer or an authorized manufacturer’s representative.
1.7. High Inlet Temperature (Hit) Function
The HIT function (provided as an option) allows the heat pump to operate even with inlet water
temperatures above the standard limits. It is utilized:
•
for the anti-Legionella treatment (tank temperature > 60 °C (>140°F), see below)
•
when domestic water recirculation is used with low water demand
•
when heat pump stops for a long time and the tank thermally stratifies.
