(only applicable in case of hybrid system)
The communication cable between the gas boiler and
the indoor unit is properly mounted.
The system is properly earthed and the earth terminals
are tightened.

▪ 0=for EH EHYHBH08
▪ 1=for EHYHBX08
The minimum water volume is guaranteed in all
conditions. See "To check the water volume" in
"3.2 Preparing water piping" on page 4 .
INFORMATION
The software is equipped with an "installer-on-site" mode
([4‑0E]), that disables automatic operation by the unit. At
first installation, setting [4‑0E] is by default set to "1",
meaning automatic operation is disabled. All protective
functions are then disabled. If the user interface home
pages are off, the unit will NOT operate automatically. To
enable automatic operation and the protective functions,
set [4‑0E] to "0".
12 hours after the first power-on, the unit will automatically
set [4‑0E] to "0", ending "installer-on-site" mode and
enabling the protective functions. If – after first
installation – the installer returns to the site, the installer
has to set [4‑0E] to "1" manually.
6.2 Checklist during commissioning
The minimum flow rate is guaranteed in all conditions.
See "To check the water volume and flow rate" in
"3.2 Preparing water piping" on page 4 .
To perform an air purge .
To perform a test run .
To perform an actuator test run .
Underfloor screed dryout function
The underfloor screed dryout function is started (if
necessary).
To perform an air purge on the gas supply .
To perform a test run on the gas boiler .
6.2.1 To check the minimum flow rate
1 Confirm according to the hydraulic configuration which space
heating loops can be closed due to mechanical, electronic, or
other valves.
2 Close all space heating loops that can be closed (see previous
step).
3 Start the pump test run operation (see "6.2.4 To perform an
actuator test run" on page 21 ).
4 Go to [6.1.8]: > Information > Sensor information > Flow rate
to check the flow rate. During pump test run operation, the unit
can operate below this minimum required flow rate.
