E 19
Input measurement of water flow
selection with water flow meter Inadequate internal heating
water upon demand Parameters are set
incorrectly on TsP menu
1-) Call the authorized service first
2-) TsP Parameter P01=0 default value must be set only by the
authorized service
E 20

> Installation clogging
1-) First restart the boiler by pushing RESET button, and check if
problem is solved
2-) Check if the boiler central heating system valves are open, if
not, open all of them
3-) Check if all radiator valves are open, if not open, minimum 3
meter-radiators must be on
4-) RESET the boiler, and check if the problem is solved
2-) Call Authorized service if the fault remains unsolved.

supply and Return > TSP 82 value °C The boiler does not operate, E21
error code blinks
> Insufficient/no water in
the system
> Pump clogging
> Pump fault
> Pump equipment
> Equipment clogging
1-) Restart the boiler by pushing RESET button, and check if
problem is solved.
2-) Check if the boiler heating system valves are open, if not,
open all of them.
3-) Check if all radiator valves are open, if not open, minimum 3
meter-radiators must be on
4-) Restart the boiler by pushing RESET button, and check if
problem is solved.
5-) Call Authorized service if the fault remains unsolved.
E 28
Permitted maximum consecutive
number of resetting is reached Permitted number of RESET is
reached.
Due to other possible
causes, too many
consecutive blocking
(subsequently resetting)
fault
1-) Disconnect the power supply, and resetting will be permitted
2-) Find the root cause of the error code to solve3-) Call
Authorized service if the fault remains unsolved.

Abnormal low voltage
The boiler does not operate, E01
error code blinks
Low voltage in < 165 VAC
Electricity mains operation
mode +/- %5 OR in
Automatic calibration mode
< 182 VAC +/- %5
1-) Restart the boiler by pushing RESET button.
2-) Call the authorized service if fault remains unsolved.
E 40
Incorrect mains frequency
measurement The boiler does not operate,
E40 error code blinks
Incorrect frequency
measurement, in mains
different than 50 Hz +/-%5 1-) Call the electricity company
2-) If the supplied frequency is 50 Hz +/- %5, the fault will be
solved

loss
The boiler does not operate, E41
error code blinks
> Too much domestic water
demand within a short
period (1 minute)
> Low gas pressure
1-) Restart the boiler by pushing RESET button.
2-) Call the authorized service if fault remains unsolved.
E 42 Button failure
The boiler does not operate,
E42 error code blinks
Parameters are set
incorrectly on TsP menu
