The control module responds to signals from the room thermostat and boiler limit circuit to operate the boiler circulator, pilot burner, gas valve and vent damper. When room thermostat calls for heat, the control module starts the system circulator and activates the vent damper (causing it to drive open). When the vent damper has opened completely, the control module opens the pilot valve and activates pilot ignition spark.

For natural gas, the control module allows up to 15 seconds to establish pilot flame. If flame is not sensed within 15 seconds, the control module will turn off the gas valve, flash the Flame light, and immediately start a new cycle. This will continue indefinitely until pilot flame is established or power is interrupted. Once pilot flame is proven, the control module opens the gas valve to allow main burner flame.

For propane gas, the control module allows up to 15 seconds to establish pilot flame. If flame is not sensed within 15 seconds, the control module will turn off the gas valve, flash the Flame light, wait 1 minute, then start a new cycle. If flame is still not sensed after the second trial, two more attempts are made with 5 minute and 60 minute wait periods in between. If flame is not sensed after 4 tries, control will lockout and flash all lights. Control must be manually reset to place back into service. Once pilot flame is proven, the control module opens the gas valve to allow main burner flame.
