12.3 Explanation of the different sequence modes

Operation

This is the control unit voltage supply.

System test

In this status mode, the control unit undergoes

an internal test to verify correct functionality of the

hardware and software.

Preconditions for burner start-up

The control unit verifies that the air pressure switch

is in the depressurised position and a test of the

fuel cut-off valve is carried out.

Heating requirement

The operating thermostat closes and voltage is

supplied to connection 5 so that the control unit

can start the burner.

Pre-purge begins

The control unit starts the fan. Connections 6 and

Damper motor opens

Control unit connection 9 sends a command to the

damper motor to run at Max. mode. The control

unit detects that the damper motor’s end position

switch indicates successful transition to the Max.

load mode by supplying voltage to the connection

8 input. The control unit also performs a test

to ensure that the air sensor detects airflow by

monitoring connection 14.

Pre-purge

The combustion chamber is ventilated.

Damper motor closes

Following pre-purge, the control unit closes

connection 10. The control unit detects that

the damper motor is in the Low Load mode by

supplying voltage to connection 8 on the control

unit.

Ignition on

The control unit supplies voltage to the ignition

transformer by activating connection 16.

10.

Fuel on

The control unit activates the fuel valve by

supplying voltage to connections 17 and 18 as well

as to direct ignition systems.

11.

Flame indication

Ignition transformer turns off. The flame signal is

tested during this stage. If no flame is detected,

the burner enters Lockout mode.

12.

Operating mode

Once a flame is stable, the control unit transitions

to Operating mode. There must be a flame signal.

Voltage is supplied to connection 20.

13.

Shutdown

Shutdown occurs when the heating requirement

is met and power is cut off to the operating

thermostat connection 5 . The control unit closes

the fuel valves by cutting off power to outputs

18 and 20. The fan post-purges the combustion

chamber.

14.

Lockout

The control unit enters lockout mode when an

internal or external fault is detected. The reset

button and the remote-reset connection can be

used to disable Lock mode. However, the control

unit will revert to lockout mode if the fault is not

rectified.

Burner Lockout

When lockout occurs, the LEDs indicate the cause. The control unit status is

saved in the memory, even in the event of a power outage. By pressing the

manual reset button on the control unit or remote reset.
