9.2 REPLACEMENT OF ELECTRIC Heater SAFETY
THERMOSTAT
This equipment has a manual-reset safety thermostat connect-
ed in series with the heating element immersed in water, which
interrupts the power supply in case of overtemperature inside
the tank.
If necessary, proceed as follows to reset the thermostat (re-
served for qualified technical personnel):
• Unplug the product.
• Remove any air ducts.
• Remove the top cover by first undoing the locking screws (fig.
73).
• Remove the front panel and manually reset the tripped safety
thermostat (fig. 74). In case of intervention, the central pin of
the thermostat comes out by about 2 mm.
• Refit the previously removed top cover.

The intervention of the safety
thermostat may occur due to a
fault in the control board or the
ATTENTION
absence of water in the boiler
tank.
NB!: The intervention of the thermostat ex­
cludes the operation of the electrical heater
but not the heat pump system within the al­
lowed operating limits.
