OPERATION
Manual Set-Up
1. Set the ambient temperature to be maintained by each Thermostat.
2. Ensure Electrical Power and Gas Supply are turned “ON”
Automatic Operating Sequence
Start-up
1. Thermostat calls for heat and energizes the transformer relay.
2. Transformer relay contacts close and the Vacuum Pump motor is energized.
3. If the Vacuum Switch finds no fault, power is supplied to all the Burners in the Zone(s) in which the
Thermostat(s) are calling for heat.
4. At the Burner, the control module waits for the pre-purge period and then opens the fuel valve and the spark
igniter is energized. Time delay in the control module causes the Burners to light sequentially.
5. When the flame is established, the flame sensor signal returns to the control module and the ignition spark
ceases.
6. If the flame is not established, the control module will re-try the ignition cycle again in 30 seconds.
7. Should ignition continue to fail, the control module will make 3 ignition attempts every hour.
8. If it does not, or if it continues to “not establish a flame”, Trouble-Shoot to find the cause.
9. System operates until Thermostat(s) temperature setting is reached.
Shut Down
1. When the Thermostat has been supplied sufficient heat, its contacts open and de-energize the transformer
relay.
2. The contacts of the transformer relay open and Electrical Power to the Burners and Vacuum Pump is
disconnected.
3. A post purge cycle can be provided when a Control Panel is supplied.
4. System remains ‘OFF’ until ambient temperature falls below the Thermostat(s) setting.
5. System cycles through Steps 1 to 9 on a continuous basis until Power is turned OFF.
