Boiler overheating
If the temperature of the boiler raises to more than 105 °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.
Methods of regulation of the ATTACK DPX PROFI boiler
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 suction fan switches off and
the boiler starts burning at the temperature of 65 °C.
For the purposes of timing regulation by room temperature it is possible to connect any arbitrary
programmable thermostat with the terminals for the sensor of room temperature. 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.
The mixing valve with the electric drive can be also connected to the boiler regulator . (This system
is not standardly delivered with the boiler).
Error messages
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 breakdown it is
necessary to switch the boiler off by the main switch,to assure the continuous operation of the
central heating pump by plugging into the mains, the 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.
