Anti-scalding protection
Your contractor can set a permanent temperature limit
(see chapter “Customer service mode”) to prevent any
water being drawn from the appliance at temperatures
that could lead to a risk of injury.
Air detection
The appliance is equipped with an air detector that
largely prevents damage to the heating system. If, during
operation, air is drawn into the instantaneous water
heater, the equipment shuts down the heating load for
one minute, thereby protecting the equipment.
