Preconfiguration of the Heat Pump Heating System
The following presettings must be carried out:
Preconfiguration of all system components for
dynamic menu structuring
Monovalent (heat pump as sole heat
generator), mono energy (heat pump and
immersion heater), bivalent-parallel (heat
pump and boiler), bivalent-alternative (heat
pump or boiler), bivalent-renewable (heat
pump or renewable heat source)
Is an internal or external thermal energy meter
(WMZ 25 or WMZ 232) present in the system?
The thermal energy meter emits a pulse of at
least 2 seconds per kWh. The pulses are added
together depending on the mode of operation.
Is the additional heat exchanger that is
integrated into the heat pump connected for
waste heat recovery (DHW / swimming pool)?
Are several heat pumps running parallel in a
network? (Observe the operating instructions for
parallel connection!)
Is the master controller to take on a central or
decentralised function in network operation in
relation to swimming pool water and DHW
preparation? (Observe the operating
instructions for parallel connection!)
Is a four-way valve present in the heating
circuit? (Observe the installation instructions for
four-way valves!)
How is the flow through the heat pump's
liquefier implemented in the heating circuit?
Does the system have a 2nd heating circuit in
which a mixer is controlled?
Does the system have a 3rd heating circuit in
which a mixer is controlled?
Is the active cooling function of the reversible
heat pump used?
Is a passive cooling controller connected to the
heating controller?
Is a 2 or 4-pipe system used for passive
cooling?
Is DHW heating carried using by the heat
pump?
Is a sensor or thermostat used to regulate DHW
heating?
Has a flange heater for reheating and thermal
disinfection been installed in the DHW cylinder?
Is a circulation pump present?
Is the heat pump used for heating swimming
pool water?
