Important points to check
During the first period after commissioning you should pay special attention to the pressure levels in
the heating system and heat transfer circuit. It might need filling up.
The factory setting of the motor cutout is based on a value during hot water charging and a stable
voltage. Because of the fluctuating voltages on the mains supply the recommended settings are not
always suitable and can therefore need adjusting from time to time. This is best achieved using a clip-
on ammeter during hot water operation.
For the heat pump to perform at its best, it is important to check the flow on the hot and cold side of
the heat pump. Usually, the heat transfer fluid pumps each have a speed selector switch. These must
be set correctly for the pressure drop in the systems. A recommended temperature difference over
the heat pump on the cold side is between 2-3°C and on the hot side between 7-10°C. You can
check this with the help of the sensor temperatures in line three of the control panel.
It is also important that the flow in the radiator system exceeds the flow across the heat pump. If this
is not the case, the heat pump flow goes back via the bypass to the heat pump return, which may
cause the heat pump to trip for high return temperature. The flow through the radiator system must
be high enough to ensure that the
entire surface of the radiators is kept hot. This maximises the heat-
radiating surface and so keeps down the flow temperature from the heat pump.
After testing, vent the system again and top up with cold water if necessary.
