6.7.5.5 Pump (circulation pump)
Heat pump
Pump
The menu is only displayed in the Expert level.
Parameters
Setting
Switch-on type
Operating mode of circulation pump during heating operation.
Constant operation
:
Pump is operated with the
Load
set.
Volumetric flow
:
The pump modulates depending on the volumetric flow.
Load …
Load of the pump during constant operation.
The parameter is only displayed, if the
Switch-on type
is set to
Constant
operation
.
The load can be set individually for operating modes heating, cooling and DHW.
6.7.5.6 Heating
Heat pump
Heating
The menu is only displayed in the Expert level.
Parameters
Setting
Switch differential
Switch hysteresis for the heat pump in heating operation.
The flow temperature must be below the required flow setpoint temperature by at
least the
Switch differential
to ensure the heat pump starts.
If the
Dynamic switch differential
function is activated, the spread of
the flow and return is recorded when the heat pump is switched off and added to
the
Switch differential
Load limit
Upper limit for heat pump capacity in heating operation.
6.7.5.7 Cooling
Heat pump
Cooling
The menu is only displayed in the Expert level.
Parameters
Setting
Switch differential
Switch hysteresis for the heat pump in cooling operation.
The flow setpoint temperature required must be below the current flow temperat-
ure by at least the
Switch differential
to ensure the heat pump starts.
Load limit
Upper limit for heat pump capacity in cooling operation.
