NOTICE
ALWAYS operate the unit with thermistors and/or pressure
sensors/switches. If NOT, burning of the compressor might
be the result.
NOTICE
Make sure that both the domestic hot water tank and the
space heating circuit are filled before turning on the power
of the unit.
If not filled before turning on power, and in case
Emergency is active, the backup heater thermal fuse may
blow. To avoid breakdown of the backup heater, fill the unit
before turning on power.
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.
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

The system is properly earthed and the earth terminals
are tightened.
The fuses or locally installed protection devices are
installed according to this document, and have NOT been
bypassed.
The power supply voltage matches the voltage on the
identification label of the unit.
There are NO loose connections or damaged electrical
components in the switch box.
There are NO damaged components or squeezed
pipes on the inside of the indoor unit.
Backup heater circuit breaker F1B (field supply) is
turned ON.
The correct pipe size is installed and the pipes are
properly insulated.
There is NO water leak inside the indoor unit.
The air purge valve is open (at least 2 turns).
The domestic hot water tank kit has been installed on
the cold water inlet of the DHW tank. The pressure relief
valve (DHW circuit) purges water when opened. Clean
water MUST come out.
The pressure relief valve (space heating circuit) purges
water when opened. Clean water MUST come out.
The shut-off valves are properly installed and fully open.
The domestic hot water tank is filled completely.
The central water loop circuit and water circuit are
filled correctly.
NOTICE
When the central water loop circuit is not ready to be used,
the system can be set to Compressor forced off mode.
To do this, set [9.5.2]=1 (Compressor
enabled).
Space heating and domestic hot water are then provided
by the backup heater. Cooling is NOT possible when this
mode is active. All commissioning related to or making use
of the central water loop circuit should NOT be performed
until the central water loop circuit is filled and Compressor
forced off is deactivated.
