System-specific parameters
For each day of the week, it is possible to select
whether Time1, Time2, no time or both times
are to be active when the speed is lowered.
Operations to lower the temperature that
exceed a weekday are activated or deactivated
at the end of each day accordingly.
Enter the power output of the heat pump at the
standard measuring point (B0W35, W10W35,
A7W35) according to the type plate. Only
outputs which can be found on the type plates
can be selected.
Setting the lower operating limit for the use of
the ground water as heat source or for waste
heat reduction via intermediate heat exchanger
Has flow rate monitoring been implemented in
the primary circuit?
Has flow rate monitoring been implemented in
the secondary circuit?
Settings for the 2nd heat generator to
supplement heat pump heating operation in
bivalent and mono energy systems
The 2nd heat generator is only necessary from
a particular limit temperature onwards,
depending on the dimensioning of the heat
pump system. The 2nd heat generator is not
switched on until the temperature sinks below
the set limit temperature.
A variably-regulated 2nd heat generator has its
own external temperature-guided regulation.
Full volume 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 regulation.
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).
Utility 1: The 2nd heat generator is only
enabled at bivalence level B3 during the utility
block. The immersion heater of mono energy
systems is always blocked.
Utility 2: The 2nd heat generator is enabled
during the utility block.
Utility 3: The 2nd heat generator is enabled
during the utility block if the utility 3 limit
temperature is also undershot.
Limit temperature for enabling the 2nd heat
generator when setting utility 3.
