Controller failures
The controller is constantly testing if its internal circuits and temperature sensor are
working correctly. After detection of fault, it stops the fan, turns on the central
heating pump and shows proper error message on the display. In case of failure
please turn off the controller, plug the central heating pump to the power source,
ensure appropriate fuel firing in the boiler and contact the service.
When [E 1] error appears on the display, it means fault in the boiler sensor circuit
or temperature below 0°C. [E 2] is displayed if boiler overheats. [E 3] error means
fault and overheating at the same time. Appearing of [E 1] error on the display after
erasing it by pressing STOP button, in spite of temperature decreasing below
90°C, may mean permanent damage of boiler temperature sensor (e.g. if the boiler
has been overheated above 150°C). In case of programming the sensor and
central heating pump in the service mode the controller tests the hot water sensor
circuit. Appearing of fault [E8] means damage or lack of hot water sensor.
