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, 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. 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.
5.13
To connect the brine low pressure
switch
Depending on the applicable legislation, you might have to install a
brine low pressure switch (field supply).
NOTICE
We recommend to use a mechanical brine pressure
switch. If an electrical brine pressure switch is used,
capacitive currents might disturb the flow switch operation
causing an error on the unit.
