The boiler overheating
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 options of boiler regulation ATTACK DP PROFI
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 purposses of timing regulation by room temperature it is possible to connect any
optional 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
12V electric drive can be also connected to the boiler regulator . (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,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.
