Configuring the Heat Pump Heating System
System-specific parameters
A variably-regulated (gliding) 2nd heat
generator has its own external temperature-
guided regulation and can be flowed through
with the full volume as required.
A constantly-regulated 2nd heat generator is
set to a constant temperature. The mixer
regulation 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 optimal 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 (EVU) 1: The 2nd heat generator is only
enabled in the B3 bivalence level during the
utility block. The immersion heater of mono
energy systems is always blocked.
Utility (EVU) 2: The 2nd heat generator is
enabled during the utility block.
Utility (EVU) 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 (EVU) 3.
The special program should be used for old
boilers or bivalent systems with main cylinders.
It will help to prevent corrosion caused by
condensation. The 2nd heat generator remains
in operation for a minimum of 30 hours after
enabling.
Temperature difference between cylinder
(renewable) and flow temperature that must be
overshot if the HP is to be blocked when a
heating request is pending
With "Comfort" setting:
A renewable heating block is only active when
the temperature in the renewable cylinder is
higher than the current return flow setpoint
temperature hysteresis.
Temperature difference between cylinder
(renewable) and hot water temperature that
must be overshot if the HP is to be blocked
when a hot water request is pending.
Parallel buffer tank temperature (renewable)
that must be overshot if the HP is to be blocked
when a request for swimming pool water is
pending
