    AILY In order to prevent sticking components, the boiler carries out a self- diagnosing test every 21 hours: the pump runs for 15 seconds and the diverter valve moves once. FROST EVICE The anti-frost function acts on the central heating flow temperature probe, independently from other regulations, when the electrical supply is turned on.
