2 Product data
With the help of the HPC400 (Procontrol 600) control unit it is
easy to control the heat pump.
You select the required room temperature in your home by
turning the menu dial. The thermostat valves on the radiators
should normally be fully open, but can be adjusted if it gets too
cold or hot in one room.
The optimised operating mode ensures the efficient use of
energy. Heating and cooling are controlled to ensure optimum
comfort with the minimum possible consumption of energy.
The heating of hot water can easily be set, and then requires
few adjustments.
2.1 Functions
The number of functions and the menu structure on the control
unit depend upon how the system is built up.
• Settings for different heating and cooling circuits are only
accessible if two or more heating/cooling circuits are
installed.
• Information on the solar heating system is only shown if a
solar heating system is installed.
There are references to indicate that functions are related to
the structure of the system where this is relevant. The range of
settings and default settings vary, depending on which system
has been installed and can deviate from the information in
these operating instructions.
Consult your installer if you have any additional questions.
2.2 Functionality of the control unit
Cooling is disabled in the UK model to
comply with the regulations for RHI.
The control unit can control up to four heating/cooling circuits.
In heating mode the control unit works with one of the main
control modes in each heating circuit. Depending on your
requirements, the installer selects one of these and sets it.
The main control modes for heating are:
• Outdoor temperature controlled:
– Control of room temperature in relation to outdoor
temperature
– The control unit adjusts the flow temperature
according to a simplified or optimised heat curve.
• Outdoor temperature controlled with input from room
temperature:
– Control of room temperature on the basis of outdoor
temperature and measured room temperature. The
room unit actuates the flow temperature on the basis of
the measured and required room temperature.
– The control unit adjusts the flow temperature
according to a simplified or optimised heat curve.
2.3 Operation after power failure
In the event of a power failure, or periods with disconnected
heat source, no settings are lost. The control unit starts again
when the power returns. It may be necessary to redo the
settings for the time and date. No other settings are necessary.
For outdoor temperature controlled
adjustment with input from room temperature
the following applies:
The thermostat valves in the reference room
(the room where the room unit is installed)
must be fully open.
