Commissioning
Functional test for
Cooling mode:
1. Switch the power supply on.
2. Open all shut-off valves
if necessary.
3. Switch the unit and
the corresponding circulation
pump on to the highest level.
The outlet temperature must
be between +4 and +18°C.
4. Switch the unit on and select
the cooling operating mode.
If the return temperature
is warmer than the setting,
the compressor display will flash
and the compressor will begin
to work after approx. 3 to
5 minutes.
5. Please note that the inlet
temperature at the nominal
flow rate of the medium lies
approx. 5 K below the return
temperature.
- If the supply temperature falls
below the factory setting of
4°C, a fault triggers.
If this is the case, a higher
return temperature must be
selected. If the spread is too
great or too small, the medium
flow rate must be checked.
- The circulation pump starts
and the controller checks
the medium flow rate via
the differential pressure/flow
switch.
If the volume is insufficient,
a fault shut-off will be carried
out and the cooling cycle will
not be enabled.
6. Measure and record all
the required values in
the commissioning report and
check the safety functions.
7. Check the unit control system
using the functions described
in the "Operation" chapter.

heating operating mode.
If the return temperature
is colder than the setting,
the compressor display will
flash and the compressor will
begin to work after approx.
3 minutes.
5. Please note that the supply
temperature at the nominal
flow volume of the medium
lies approx. 5 K above
the return temperature.
- The circulation pump starts
and the controller checks
the medium flow rate via
the differential pressure/flow
switch.
If the volume is insufficient,
a fault shut-off will be carried
out and the cooling cycle will
not be enabled.
