PROBLEM POSSIBLE CAUSE REMEDY
Radiators cold in winter
but the thermostove
boils 1. Circulator does not run because
blocked
2. Radiators have air in them
1. Free up the circulator by removing the plug and
turning the shaft with a screwdriver.
Check the electrical connections of the same,
replace if necessary
2. Vent the radiators
Hot water in not
provided
1. Circulator pump blocked 1. Free the circulator pump
The thermostove boils
under “modulation”
that reaches the
temperature set on
the thermostat of the
thermostove
1. It ‘been set to a value of
thermostat too high
2. It was set too much power to
the implant.
1. Lower the temperature in the thermostove
2. Reduce the value of operating power
The thermostove goes
into “modulation”
as it reaches the
temperature set on
the thermostat of the
thermostove even
at low temperatures
of the water in the
thermostove
1. Modify the parameter for the
maximum smoke temperature
modulation to edit
2. Dirty thermostove: the fumes
are too high temperature.
1. Contact your Authorized Assistance Center
2. Clean the tube bundle
High variability of
domestic hot water
temperature
1. Water flow is too high
1. Reduce the flow of water (4/6 liters per minute)
Exits little hot water
1. Insufficient water pressure in
the network
2. Tap or mixer clogged with
limescale
3. Water group clogged
4. The heat exchanger does not
work
5. Air in: pump cavitation for the
presence of air, the water does not
rotate.
1. Check the setting of the pressure reducing valve
2. Install a water demineralizer
3. Check and clean the sanitary kit
4. Replace the plate heat exchanger
5. Bleed the brake system, remove air by venting
the radiators.
Anomalies related to the plumbing circuit
Never turn off the heater by removing electricity. Let always complete the
shutdown cycle, otherwise you may damage the structure and have trouble
lighting in the future.
