Check list for commissioning
Adhere to the following sequence:
1) Check heating system circuit: System-
pressure, expansion vessel function,
bleeding valves, quantity adjustment
2) Check whether all non-return valves
are open
3) Check power supplies and circuit
breakers
4) Check refrigerant circuit
5) Check the electrical connections to the
system components, including all re-
quired safety equipment, according to
the wiring diagram.
6) Switch on 3-phase supply to the heat
pump.
7) Control 3-phase supply and right-hand
rotary field
8) Switch on control voltage supply
9) Configure the system by means of the
commissioning (IBN) assistant
10) Store the sensor configuration
11) Relay test on the output terminals
12) Adjust the system according to user re-
quirements and document these set-
tings
13) Hand over system to operator
6 Operating the system
The heat pump operation takes place by means
of the basic operating panel. This is easily ac-
cessible in a plastic housing mounted on the
heat pump.
The user has
2 knobs
and a lit
display
at his
disposal (Fig. 9)
Fig. 9:Basic control panel (Master remote control)
The heat pump has no separate
OFF switch. In emergency the sys-
tem MUST be switched off by means
of the specified circuit breakers.
The circuit breakers MUST be so
reachable as to ensure a switching
off at any time
