INFORMATION
This unit is a heating only model. Therefore, all references to cooling in this
document are NOT applicable.
NOTICE
Make sure both air purge valves (one on the magnetic filter and one on the backup
heater) are open.
All automatic air purge valves MUST remain open after 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
[A.6.D]: Disable protections=On. After his work is done, he can enable the
protective functions by setting [A.6.D]: Disable protections=OFF.

after it is installed and 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.
