Remember that if the operating mode OFF is to be used for long periods
during the winter, the water in the heating system in the installation
must be drained, otherwise there is a risk of frost damage.
The heat pump and the auxiliary heater are automatically controlled by the control system.
The control system is controlled so that only the heat pump unit (compressor) is allowed to
operate. In this operating mode peak heating charging (anti-legionella function) of the hot
water will not be run because auxiliary heaters must not be used.
The control system only permits the auxiliary heater to be in operation. This operating mode
can be used when a new installation is being used, when the brine system is not ready for
operation.
In this mode the heat pump only produces hot water, no heat goes to the heating system.
Meaning
Indicates that the compressor is in operation.
Indicates that the heat pump intends to produce heat to the heating system.
Indicates that the heat pump intends to produce heat to the water heater.
An "F" next to the symbol indicates that a flow sensor is installed.
Indicates that tariff control is active.
Indicates the level of hot water in the water heater. During charging, the tank is filled and fil-
ling starts at the set start temperature. A lightning symbol by the symbol indicates peak hea-
ting charging (anti-legionella function).
Either indicates that the operating pressure switch has deployed, or that the pressure pipe
temperature has reached its maximum temperature.
