7.9 ERROR MESSAGES

The connection of all sensors of the regulator is permanently monitored. If the regulator detects

that some of the sensors is not connected, the error messages are displayed. Messages about the

boiler overheating or fuel shortage are also displayed.

[FUEL] – is displayed, when there is not enough fuel in the boiler. The sufficient amount of fuel is

defined by the parameter

90, where the figure 90 is related to the adjusted value 90 °C. Then, if

the flue gas temperature decreases under this adjusted value within the time Fb30 (time of boil-

er stop by fuel shortage), the regulator displays the [FUEL] message. To start the boiler again, it is

necessary to remove the message by the STOP button and then to press the START.

[HOT] – is displayed, when the flue gas temperature exceeds the maximum permitted value set

by the parameter c300 (means 300 °C). The ventilator is stopped in this case. After the tempera-

ture decreases under the adjusted flue gas temperature, the ventilator is started again.

[E 1] – is displayed, when the boiler temperature sensor fails or when it is not connected. In such

case is the regulator taking actions to ensure the safety of the boiler – the fan is stopped (if it is

currently in operation) and the circuit pump is started for eventual safe boiler cooling. After the

cause of error is removed, the error message can be erased by the STOP button.

[E 2] – is displayed, when the boiler temperature exceeds the boiler overheating temperature

A99. The regulator stops the flue gas fan and starts the circuit pump. The error message can be

removed by the STOP button after the boiler temperature decreases to the safe value.

[E 8] – is displayed, when the additional sensor fails (in the D.H.W. tank or accumulation tank). If

this sensor works for the D.H.W. tank, the warming is blocked. If the sensor works for the accu-

mulation tank, the pump will be permanently working. This error message cannot be removed

by the STOP button. It is automatically erased after the sensor failure is repaired.

[E128] – is displayed, when the flue gas temperature sensor fails. In this case is the boiler control

switched to regulate according to the boiler temperature. The error message is erased automati-

cally after the fault of the flue gas temperature sensor is solved.

[E 3] If several failures occur in one moment, their total is displayed. In such case it is necessary to

check the functionality of all sensors.
