Overheating of the boiler
If the temperature of the boiler raises to more than 95 °C, the regulator stops the flue-gas
fan and the control light of boiler overheating shines on. For new start it is necessary to:
-
wait until the boiler temperature falls
-
remove the cause of boiler overheating (e.g. refill missing water into the central
heating circuit)
Warning! Water can be refilled only after the boiler temperature falls under 40 C.
-
Turn the button of the boiler thermostat into the maximum left position ad thus stop
the alarm
-
wait until the control light of boiler overheating starts flickering;
-
to start the regulator again, set up the required temperature of the boiler by the turning
button of the thermostat;
If the temperature falls under 60 °C, the regulator comes into the burning up mode.
The ways of boiler regulation
The boiler enables regulation of room temperature as well as connecting the sensor of room
temperature. If the room temperature is lower than the set up one, the control light near the
button of thermostat shines on, which means that the boiler must keep the set up temperature.
After reaching the required temperature the control light switchces off, the circuit pump of
central heating switches off and the boiler starts burning at the temperature of 65 °C.
For the regulation by room temperature it is possible to connect with the terminals for the
sensor of room temperature any room thermostat that can be programmable.In this case the
turning button of the room thermostat is not working.
If you do not wish to use the room thermostat nor the room sensor, the inlet terminals must be
short-circuited. In this case only the boiler thermostat is working.
To the boiler regulator can be also connected a mixing valve with an 12V electric drive. (This
system is not delivered with the boiler).
Displaying faults:
The boiler regulator constantly verifies the functions of internal systems and of the sensor of
boiler temperature. After finding out the defect, the regulator switches off the flue-gas fan, the
central heating pump and at the same time the defect shows on the display. In the case of failure
it is necessary to switch the boiler off by the main switch. Continuous operation of the central
heating pump must be assured by plugging into the mains. Fuel must be burnt thoroughly and
the contract service company contacted.
If E1 fault appears on the display, it means the damage of the sensor of boiler temperature.
