Commissioning
7.1
Overview: Commissioning
This chapter describes what you have to do and know to
commission the system after it is configured.
Typical workflow
Commissioning typically consists of the following stages:
1
Checking the "Checklist before commissioning".
2
Performing an air purge.
3
Performing a test run for the system.
4
If necessary, performing a test run for one or more actuators.
5
If necessary, performing an underfloor heating screed dryout.

Precautions when commissioning
INFORMATION
During the first running period of the unit, the required
power may be higher than stated on the nameplate of the
unit. This phenomenon is caused by the compressor, that
needs a continuous run time of 50 hours before reaching
smooth operation and stable power consumption.
NOTICE
NEVER operate the unit without thermistors and/or
pressure sensors/switches. Burning of the compressor
might result.
