Gebwell Qi Series Installation, Operation And Maintenance Manual page 37

Substitute: The electric resistor (SV1) is only used in
failure situations.
Complem operation HC: The electric resistor (SV1) is
used to supplement the compressor in heating use.
Complem operation DHW: The electric resistor (SV1)
is used to supplement the compressor in DHW use.
Complem operation HC+DHW (factory setting): The
electric resistor (SV1) is used to supplement the
compressor in both heating and DHW use.
End DHW charging: NOT IN USE
Emergency operation: NOT IN USE
Legionella function: NOT IN USE
Electric supply water prevention time (2881)
The electric resistor (SV1) is allowed to start no earlier
than the prevention time set with this parameter has
elapsed from the activation of the compressor (K1).
The prevention time is taken into consideration only when
the electric resistor (SV1) is used at setting "Supplement
to heat pump operation" (2880). If the setting of the
electric heating is set to "Replacement", the prevention
time is not taken into account.
Adjustment range: 0 - 255min
Factory setting: 30min
Electric supply water release integral
When the two- or three-step setting for the flow-through
resistor is used, the steps are released in accordance with
the release and return integral (2882 and 2883).
Adjustment range: 0 - 500°C min
Factory setting: 200°C min

Electric supply water return integral
If the actual value is higher than the activation point, the
controller switches
(controlling) step off and begins to form a release integral
based on the potential heat excess.
Then, once the heat excess reaches the set release integral
(2883), the lower step is switched off.
For a new release, the release integral must be met again.

Electric supply water free ET under
This setting is taken into account only when the flow-
through resistor (SV1) is used at setting "Supplement to
heat pump operation" (2880). At the "Replacement"
setting, the electric heater is always released.
The flow-through resistor is only released when the
damped outdoor temperature is below the temperature set
here.
