ERROR MESSAGES, PROBLEMS AND

SOLUTIONS

Code

Popup Message

Reason

E01

EEPROM error, the boiler can't save the parameters

Please restart the boiler

While writing in EEPROM (PLC memory), the PLC returns an error if

the writing operation is defective.

E02

The connector is not recognized by the boiler

Please connect the correct connector.

Checks if the code of the connected cable corresponds to one

of the defined cables. Each cable has a defined maximum power

level.

E03

The connected power connector allows more power than the

boiler can supply

Please, plug a correct cable

Checks if the power of the cable connected to the boiler is equal

to or less than the maximum power of the boiler

E04

The system has counted too many errors

Please restart the boiler

Acknowledging too many errors in a short period puts the boiler in

error mode (10 errors in 15 minutes)

E05

Warning, watchdog activated, No more communication with the

unit

Please check the communication between the display and the

control unit

The PLC and the DSP send information to each other. If one or the

other detects a loss of information, then the watchDog intervenes

and shuts down the boiler.

E06

The system detected an inversion of the temperature sensors

Please check the condition of the pump

Checks the temperature difference between the inlet and the

outlet (DELTA_T = T_OUT-T_IN) at the start of a mode (HT or DR). If

the temperature (DELTA_T) is < 0, the error pops up.

E07

The internal temperature delta is too high

Please check the condition of the pump

Checks the temperature difference between the inlet and the

outlet (DELTA_T = OUT-IN) at the start of a mode ( CH or DR). If the

temperature (DELTA_T) is > DELTA_SETPOINT (40°C by default),

the controller blocks the rise in temperature for 2 minutes.

If the temperature (DELTA_T) has not decreased, the boiler stops

heating and displays an error.

The boiler will restart heating as soon as the temperature drops

below DELTA_CONSIGNE-5°C.

E08

The system detected a loss of power

The temperature does not reach the setpoint

Please check the equipment

Each time the regulation is started, the boiler checks whether

there is a rise of temperature. If after 5 minutes the temperature

has not risen by one degree (1°c) then an error is displayed.

If after 3 attempts the boiler does not rise to temperature, then the

boiler is blocked.

E10

The system must restart before changing the operating mode

Please restart the boiler correctly

Error hardware : Changing Mode while boilers ON.

The boiler must switch OFF and restart to set Heating mode or

Drying mode

E11

The supply temperature sensor returns an error

Please check the sensor

If the temperature is outside the physical limits of -20°C and 150°C,

the boiler switches off.

E12

The input temperature sensor returns an error

Please check the sensor

If the temperature is outside the physical limits of -20°C and 150°C,

the boiler switches off.

E13

Pressure sensor returns an error

Please check the sensor

Check whether the values are within the operating range of the

sensor

E14

Hydraulic system pressure is too high

Water pressure > 2.7 Bar
