Functional test and test run
During operation of the plant
operating parameters can be called
up on the outdoor unit display.
(only RVD 521-1051DC)
The following parameters are dis-
played successively:
RVD 521-1051 DC
- Frequency of the compressor
- Operating mode
- Level fan
- Current cooling/heating perforance
- Temperature sensor liquefier
- Temperature sensor hot gas
- Temperature sensor air inlet
- Power consumption outdoor unit
- Degree of opening for electronic
Expansion valve only RVD 521 DC
- error code
Proceed as follows to call up the
operating parameters:
1. Remove the cover from the
outdoor unit.
2. Switch all indoor units on and
select cooling mode and the
highest fan speed.

12. Check all the previously
described safety devices and
functions during the test run.
13. Enter the measured data in
the commissioning report.
in the commissioning report
and familiarize the operator
with the system.
14. Remove the pressure gauge.
Check that seals have been
fitted in the sealing caps.
NOTE
Press the TEST knob on the
outdoor unit board. This
serves to set the inverter to
max. refrigerating capacity.
15. Reinstall all parts which were
removed.
