Control Of Additional Heat Source - Gebwell GEMINI 40 Installation, Operation And Maintenance Manual

Heat pump → 13/23 → 2881
Adjustment range: 0 - 255min
Factory setting: 30min
Electric output water release integral
When a two- or three-phase flow-through resistor is used, the
phases are released in accordance with the release and return in-
tegral (2882 and 2883).

Heat pump → 13/23 → 2882
Adjustment range: 0 - 500°Cmin
Factory setting: 250°Cmin
Electric output water return integral
If the actual value is higher than the activation point, the control-
ler switches the most recently activated (controlling) step off and
begins to form a release integral based on the potential heat ex-
cess.
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 output water below ET
This setting is taken into account only when the resistor control
is used to supplement the compressor use (2880). At the "Re-
placement" setting, the electric heater is always released.
The electric heater is only released when the damped outdoor
temperature is below the temperature set here.

ELECTRIC HEATER CONTROL, K6 (DHW) OP-
ERATION
NOTE! ALL ELECTRIC HEATERS MUST BE EQUIPPED
WITH THERMOSTATS!
The electric heater control K6 functions according to the factory
setting Replacement function. In this case the resistor does not
activate simultaneously with the compressor. The operation can

be changed in the user terminal's menu. The change is made in
Expert level.

DHW reservoir → 5/11 → 5060
Factory setting: Replacement
Replacement: The electric heater control ensures the charging
of domestic hot water, if the heat pump fails.
Summer: When all the heating circuits have switched to sum-
mer mode, the electric heater control ensures the charging of do-
mestic hot water from the following day.
In heating use, the resistor functions according to the Replace-
ment operation.
Always: Domestic hot water is always charged with the electric
heater.
Cooling operation: When the heat pump is in cooling operation,
the domestic hot water is charged with the electric heater.
In heating use, the resistor functions according to the Replace-
ment operation.
Legionella function: If the legionella function is programmed
to the heat pump, the operation is carried out with the K6 electric
heater control.
SETTING THE ELECTRIC HEATERS' THERMO-
STATS
The electric heaters installed in the reservoir must always be
equipped with thermostats. The resistor's thermostats must be
set to such a high set point, so that the heat pump can finish the
charging. In the heating reservoir, the thermostat's set point must
be set according to the highest heating circuit.
Example, domestic hot water:
Domestic hot water set point defined to the heat pump +55°C.
The thermostat must be set to +65°C.
This ensures that the heat pump can charge the domestic hot wa-
ter to the nominal set point.
Example, radiator heating:
The output water maximum set point defined for the radiator
heating circuit is +60°C. The thermostat must be set to +70°C.
Example, floor heating:
The output water maximum set point defined for the floor heat-
ing circuit is +40°C. The thermostat must be set to +45°C.
