Anomalies related to the plumbing circuit
PROBLEM
No increase in
temperature with
Boiler in operation
Condensation
in boiler
Radiators cold in
winter but the Boiler
boils
Hot water in not
provided
The Boiler boils
under "modulation"
that reaches the
temperature set on
the thermostat of the
Boiler
The Boiler goes
into "modulation"
as it reaches the
temperature set on
the thermostat of the
Boiler even at low
temperatures of the
water in the boiler
POSSIBLE CAUSE
1. Incorrect combustion
adjustment
2. Boiler/system dirty
3. Insufficient Boiler power
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 Boiler: the fumes are
too high temperature.
REMEDY
1. Check parameters
2. Check and clear the boiler
3. Check that the Boiler is properly sized for
the requirements of the system
1. Set the Boiler 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 60 ° C to
avoid condensation in the boiler.
Adjust the power of the pump at a
higher temperature to 60° C.
2. Checking the boiler setting (technical
parameters setting) in order to avoid
excessive fuel consumption, guarantee
the expected heating capacity and
safeguard the integrity of the product
3. Check the correct operation of the
anti-condensation valve
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 Specialised Technical
Assistance Centre
2. Clean the tube bundle
