COMMISSIONING AND MAINTENANCE

ONLY FOR GITRÈ B/100 MODELS

FAULT

CAUSE

SOLUTION

The storage cylinder safety valve keeps

opening

Storage cylinder safety valve

− Check valve setting and efficiency

Incorrect DHW circuit pressure

− Check DHW circuit pressure

DHW circuit expansion vessel

− Check the efficiency of the expansion

vessel

The DHW pump is not working

DHW pump problem

− Check/unseize the pump

− Check the electrical connection be-

tween the pump and the control panel

Storage cylinder temperature sensor

problem

− Check the positioning of the storage

cylinder temperature sensor

Insufficient domestic hot water

Incorrect pressure in DHW circuit

− Fit a pressure limiter

Lime scale or deposits in storage cylinder

− Check and clean as necessary

− Check the setting of the storage cylinder

thermostat

Storage cylinder thermostat

− Check the setting of the storage cylinder
