This chapter describes what you have to do and know to commission the system
after it is installed.
Typical workflow
Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing a test run for the system.
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
Before starting up the system, the unit MUST be energised for at least 6 hours to
avoid compressor breakdown during startup.
NOTICE
ALWAYS operate the unit with thermistors and/or pressure sensors/switches. If NOT,
burning of the compressor might be the result.
NOTICE
ALWAYS complete the refrigerant piping of the unit before operating. If NOT, the
compressor will break.
NOTICE
Cooling operation mode. Perform the test run in cooling operation mode so that
stop valves failing to open can be detected. Even if the user interface was set to
heating operation mode, the unit will run in cooling operation mode during 2‑3
minutes (although the user interface will display the heating icon), and then
automatically switch to heating operation mode.
