System-specific parameters
The special program should be used for old
boilers or bivalent systems with main cylinders
to help 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 heat pump 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 domestic hot water
temperature that must be overshot if the heat
pump is to be blocked when a DHW request is
pending.
Parallel buffer tank temperature (renewable)
that must be overshot if the heat pump is to be
blocked when a swimming pool water request
is pending.
Settings for heating circuit 1
The following heating regulation options are
available for heating circuit 1:
* Return flow temperature regulation based on
the external temperature and the set heating
curve
* Return flow temperature regulation via a fixed
setpoint (horizontal heating characteristic
curve)
* Return flow temperature regulation based on
the room temperature in a reference room
The heating curve end point should be set
according to the design of the heating system.
This should be done by entering the maximum
return flow temperature, which is the product of
the maximum calculated flow temperature
minus the temperature difference in the heating
system (spread).
Sets the desired return flow set temperature
when fixed setpoint control is selected
Sets the desired room set temperature and I
ratio when room temperature regulation is
selected
Sets the minimum return flow temperature
when room temperature regulation is selected
Different maximum temperatures are
permissible for panel and radiator heating
systems. The upper limit of the return flow set
temperature can be set between 25 °C and
70 °C.
