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
motorized 3‑way valve delivered with the domestic hot water tank.
▪
The safety thermostat setpoint is at least 15°C greater than the maximum leaving
water temperature setpoint.
INFORMATION
ALWAYS configure the safety thermostat after it is installed. Without configuration,
the unit will ignore the safety thermostat contact.
INFORMATION
The preferential kWh rate power supply contact is connected to the same terminals
(X5M/3+4) as the safety thermostat. It is only possible for the system to have EITHER
preferential kWh rate power supply OR a safety thermostat.
