Activating The Ground Source Heat Pump; Before Activation; Activation; Operation Without A Collector And At A Worksite - Gebwell Qi Series Installation, Operation And Maintenance Manual

10 ACTIVATING THE
GROUND SOURCE HEAT
PUMP
Upon delivery, all the pump's motor protection switches
and circuit breakers are in the 0 position.
The power switch PT serves as the pump's main switch.

10.1 Before activation

Before activating the ground source heat pump, ensure
that
•
the collector has been filled with heat transfer
liquid
•
the heat pump accumulator (LVV1) has been
filled from the heating and domestic water side
•
the accumulator's (LVV1) outer housing has
been vented
•
the outdoor sensor has been connected
•
the heating sensors have been connected
•
the electrical connections are correct
•
the compressor's motor protection switch (F1) is
in the OFF position.
•
the resistor cartridge's circuit breaker (F2) is in
the OFF position.
•
the circuit breaker (F3) of the source and heat
supply pumps (P1 and P2) is in the OFF position.

10.2 Activation

•
Insert the heat pump plug (PT) into the socket.
•
Set circuit breaker F10 to the I position.
•
Perform all plant-specific settings. For this
purpose, you must select the Expert –user level:
30
10.3 Operation without a collector and at a
worksite
The ground source heat pump can be used for heating even
before the collector is connected. In this case, all heat is
generated using direct electrical resistor power, and the
maximum heating power is 3 kW/6 kW/9 kW (see
"Technical specifications - Flow-through resistor
power"). However, all control functions of the heating
and domestic water side are available. Please note that the
heating and domestic water circuits must be connected
and vented, and all electrical connections must be in order.
If you want to use the ground source heat pump for
worksite heating, set the device to the "Emergency
operation" mode, which ensures that the compressor (K1)
and source pump (P1) are not activated. The heat pump
will then make sure that the domestic water and heat will
be produced using the electric resistor (SV1). Emergency
operation is activated on Special operations –menu. While
device is in emergency operation mode, the display will
feature symbol.

10.4 Venting

The collector must be vented extremely thoroughly.
Even a small amount of air in the brine collector will
prevent the pump from functioning normally and can
cause it to break down.
In order to facilitate commissioning and troubleshooting,
the controller features an input and output test function.
You must be on the "Expert" level to use this function.
The source and heat supply pumps can be vented using
this function.
