System-specific parameters
Enter the power output of the heat pump at the .
point (air-to-water HP at A7W35, brine-to-water HP at B0W35, water-
water HP at 10W35) pursuant to the type plate.
outputs which are stated on the type plate of the heat pump can be
selected.
Setting the lower operating limit for the use of the ground water as
heat source or for waste heat use via intermediate heat exchanger.
Depending on the heat pump type, the operating range (brine) of
the heat source can be expanded as required. In this case, the
minimum brine concentration must be adjusted to 30 %.
Does a flow rate monitoring take place in the primary circuit?
Does a flow rate monitoring take place in the secondary circuit?
The limit temperature of the 2nd heat generator is to be selected
according to the configuration of the heat pump heating system.
Below the parallel limit temperature, the heat pump and the 2nd
heat generator operate to heat the building. The switching on of
the 2nd heat generator occurs when temperatures are below the
parallel limit temperature that has been set and performance level
3. If parallel operation is not required, the parallel limit temperature
is to be adjusted alternatively to the limit temperature.
If the alternative limit temperature and performance level 3 are
undershot then only the 2nd heat generator is used to heat the
building. The heat pump is blocked from this time onwards
A variably-regulated (gliding) 2nd heat generator has its own
control. The full volume flow can flow through it when required.
A constantly-regulated 2nd heat generator is set to a constant
temperature. The mixer control is active.
The runtime between the OPEN and CLOSED end positions
varies according to the mixer used. The mixer runtime should be
adjusted to ensure optimum temperature control.
The mixer hysteresis forms the neutral zone for operation of the
2nd heat generator. If the set temperature plus hysteresis is
reached, a "Mixer closed" signal is generated. If the set
temperature minus hysteresis is undershot, a "Mixer open" signal
is generated.
This setting determines the response of the 2nd heat generator
during a utility block (interruption of the supply voltage).
Performance level 3: The 2nd heat generator is only enabled in
performance level 3 during the utility block. The immersion heater
of mono energy systems is always blocked.
Permanent: The 2nd heat generator is enabled during the utility
block.
Limit temperature dependent: The 2nd heat generator is enabled
during the utility block if the limit temperature is also undershot.
Limit temperature for enabling the 2nd heat generator when setting
is dependent on the limit temperature.
The special program should be used for old boilers or bivalent
systems with main cylinders to help prevent corrosion caused by
condensation. On enabling the 2nd heat generator this remains in
operation for at least the number of hours that are set.
