Testing The Regulator Outputs - ATTACK DPX15 Instructions For Use Manual

[h 2] Hysteresis of boiler temperature – defines the difference between the adjusted and the
current boiler temperature for which must the boiler temperature decrease to start the
controller again after the adjusted boiler temperature is achieved.
[A 99] Temperature of boiler overheating – defines the value of boiler temperature to activate
the alarm of the boiler overheating.
[Fd60] Duration of boiler stop by ignition and fuel shortage – this parameter defines the
maximum time between starting the controller by the START button and achieving the
controller´s operating mode (reaching the flue gas temperature of [
90] is not reached during the heating up, the fan is stopped and the alarm FUEL (fuel shortage) is
displayed.
[Fb30] Duration of boiler stop by flue shortage and burn-down – the fuel amount test is
activated in the operating mode, when the flue gas temperature decreases under the parameter
[ c 90] or (if the flue gas sensor is not connected) when the boiler temperature decreases under
the adjusted parameter [L 45]. If the temperature does not exceed the necessary limit during this
period, the controller displays FUEL alarm.
 [Ar 0] parameter – indicates start of the automatic boiler (e.g. gas or pellet boiler). When the
controller is started and the boiler generates heat, the automatic boiler is stopped. Operation
of the automatic boiler is blocked by the controller in the operating mode. The automatic
boiler is started by controller, when the fuel is burned down in the boiler and the FUEL alarm
is displayed.
 [Ar 1] parameter – indicates that the additional multifunctional output will be used for error
messages like boiler sensor failure, overheating or fuel shortage.
c
[ 240] Adjusted flue gas temperature – the controller will struggle to reach and to keep this
value. The flue gas temperature sensor is turned off, if this parameter is set to „- -".
[ c h5] Hysteresis of flue gas temperature – defines the difference for which must the flue gas
temperature decrease to increase the fan rotations.
c
[ t 5] Time constant of stabilization the flue gas temperature – defines the period of
adjusting the fan rotations during stabilization of the flue gas temperature. If the flue gas
temperature exceeds the value given by the parameter [
the fan rotations gradually, until the flue gas temperature decreases to the adjusted value. If the
flue gas temperature decreases to the value of flue gas temperature hysteresis, the controller
starts to increase the fan rotations gradually.
c
[ F10] Blower speed jump while stabilizing exhaust gas temperature – defines the change
of rotations to achieve the adjusted flue gas temperature.
[ c 90] Flue gas temperature by fuel shortage – the message „FUEL" for fuel shortage is
displayed after the flue gas temperature decreases under this value.

3.8 TESTING THE REGULATOR OUTPUTS

It is possible to make a check to test the correct functionality of the regulator and devices
connected. The correct function of fan is tested by selecting the [outΠ] on display and holding
the „OK" button. Test of the circuit pump is done by selecting the [outP]. Select the [outu] to
start the additional output and [outr] for multifunctional additional output.
