10 Commissioning
INFORMATION
Protective functions – "Installer-on-site mode".
The software is equipped with
protective functions, such as room antifrost. The unit automatically runs these
functions when necessary. (If the user interface home pages are off, the unit will not
operate automatically.)
During installation or service this behaviour is undesired. Therefore, the protective
functions can be disabled:
▪
At first power-on:
The protective functions are disabled by default. After 36 h
they will be automatically enabled.
▪
Afterwards:
An installer can manually disable the protective functions by setting
[4‑0E]=1. After his work is done, he can enable the protective functions by setting
[4‑0E]=0.
10.1 Overview: Commissioning
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.
10.2 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
ALWAYS operate the unit with thermistors and/or pressure sensors/switches. If NOT,
burning of the compressor might be the result.
10.3 Checklist before commissioning
After the installation of the unit, first check the items listed below. Once all checks
are fulfilled, the unit must be closed. Power-up the unit after it is closed.
