water and preventing overpressure in the tank.
5.3
Temperature adjustment
IMPORTANT:
The adjustable thermostat allows power consumption to be optimized according to the comfort
required (hot water temperature). However, in order to prevent “legionella” bacteria to form it is advisable not to
allow the stored water temperature to become too low. Therefore, comply with the following general prevention
measures:
