ATTACK DP STANDARD Instructions For Use Manual page 17

control light of the room thermostat will shine, because the boiler should keep the temperature
set by the boiler thermostat. When the room temperature exceeds the set temperature, control
light of the room thermostat expires and the boiler switches into the mode of fire keeping at
minimum boiler temperature.
Device is designed to enable connection of alternative external thermostat instead of the room
temperature sensor. Short circuit of contacts in case of low temperature starts the heating
process described above. When contacts are open, the regulator will keep the minimum boiler
temperature.
Attention! If the external thermostat is connected at the place for connection of the room
temperature sensor, temperature set by the room thermostat button has no influence on
regulation process and the room temperature will depend only on the temperature set by the
external temperature.
Parameter [Fc 1] - means that exhaust gas temperature sensor is connected to the additional
sensor connection. In this case the value set with additional thermostat knob specifies desired
exhaust gas temperature. If the controller is in WORK mode and boiler water temperature has
reached value set with [P 65] parameter, then exhaust gas temperature drop below temperature
set with additional thermostat knob will stop the fan. If central heating pump is in [Pr 1] mode,
the pump will also stop in this case. Additionally, if exhaust gas temperature is below desired
temperature, this will also be signalled with quick blinking of thermostat indicator.
Error messages
Boiler regulator permanently tests correct function of the internal systems and of the boiler
temperature sensor. When the error is detected, regulator stops flue gas fan, C.H. pump and at
the same, the appropriate error message is displayed. In case of accident it is necessary to stop
the boiler by the main switch. Ensure permanent operation of the circuiting pump by direct
connection to the electricity mains. Ensure proper fuel combustion in the boiler and contact
contracted Service Company.
When the error [E 1] is displayed, it means fault (short circuit) in the circuit of the boiler
temperature sensor or temperature under -9°C. The [E 2] is displayed, if the boiler is being
overheated. The [E 3] means error and overheating at the same time. When the [E 1] error is
displays without possibility to remove it by pressing the STOP button, despite the boiler
temperature is under 90°C, it might mean permanent damage of the boiler temperature sensor
(e.g. in case, that the boiler was overheated to the temperature over 150°C). Error [E 8]
indicates flue gas sensor failure. In this case, the regulator will not control fuel shortage.
Disassembly of appliance
In case of need, disassembly regulator from system:
- turn the main switch off
- disconnect boiler from electricity mains
- unmount cover of the boiler´s control panel
- disconnect all connectors with cables from regulator
- unmount regulator from opening on the control panel of the boiler
WARNING: TO PREVENT FROM INJURY BY ELECTRICITY, DO NOT
!
UNMOUNT THE COVER BEFORE DISCONNECTION FROM ELECTRICITY
MAINS.
