NOTICE
Make sure to select and install the safety thermostat
according to the applicable legislation.
In any case, to prevent unnecessary tripping of the safety
thermostat, we recommend the following:
▪ 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
ALWAYS configure the safety thermostat after its
installation. 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. It is only possible for the system to have
EITHER preferential kWh rate power supply OR a safety
thermostat.

After connecting the electrical
wiring to the indoor unit
To prevent water ingress to the switch box, seal the low voltage
wiring intake using the sealing tape (delivered as accessory).
