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.

Error. If you remove the jumper (open circuit) but do NOT
connect the safety thermostat, stop error 8H-03 will occur.
