PROBLEM
Condensation
in boiler
Radiators cold
in winter but the
thermostove boils
Hot water in not
provided
The thermostove boils
under "modulation"
that reaches the
temperature set on
the thermostat of the
thermostove
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 boiler
High variability of
domestic hot water
temperature
Exits little hot water
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.
POSSIBLE CAUSE
1. Incorrect setting maximum
water temperature in the boiler
2. Insufficient fuel consumtion
1. Circulator does not run
because blocked
2. Radiators have air in them
1. Circulator pump blocked
1. It 'been set to a value of
thermostat too high
2. It was set too much power to
the implant.
1. Modify the parameter for the
maximum smoke temperature
modulation to edit
2. Dirty stove: the fumes are too
high temperature.
1. Water flow is too high
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.
REMEDY
1. Set the stove to a higher temperature. The
maximum water temperature in the boiler is 65 ° C
and can not be set below 40 ° C or above 80 ° C. It
is advisable to never adjust the temperature below
50/55 ° C to avoid condensation in the boiler.
Adjust the power of the pump at a higher
temperature to 50/55 ° C.
2. Contact your Authorized Assistance Center
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
1. Free the circulator pump
1. Lower the temperature in the boiler
2. Reduce the value of operating power
1. Contact your Authorized Assistance Center
2. Clean the tube bundle
1. Reduce the flow of water (4/6 liters per minute)
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.
