Fix the cable with cable ties to the cable tie mountings.
INFORMATION
Installation of a safety thermostat (field supply) is required
for the main zone, otherwise the unit will NOT operate.
NOTICE
A safety thermostat MUST be installed on the main zone to
avoid too high water temperatures in this zone. The safety
thermostat is typically a thermostatically controlled valve
with a normal closed contact. When the water temperature
in the main zone is too high, the contact will open and the
user interface will show a 8H‑02 error. ONLY the main
pump will stop.

Fix the cable with cable ties to the cable tie mountings.
NOTICE
Make sure to select and install the safety thermostat for the
additional zone according to the applicable legislation.
In any case, to prevent unnecessary tripping of the safety
thermostat, it is recommended that …
▪ … the safety thermostat is automatically resettable.
▪ … the safety thermostat has a maximum temperature
variation rate of 2°C/min.
▪ … there is a minimum distance of 2 m between the
safety thermostat and the 3‑way valve.
INFORMATION
After it is installed, do NOT forget to configure the safety
thermostat for the additional zone. Without configuration,
the indoor unit will ignore the safety thermostat contact.
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/9+10) as the safety
thermostat for the additional zone. It is only possible for the
system to have EITHER preferential kWh rate power
supply OR a safety thermostat for the additional zone.
