4.5.6 Continuous Pilot with COF
Continuous Pilot mode (option 111) allows the MM to shutdown the main flame and run on only a pilot flame
when the main stat turns off (when the boiler reaches its setpoint) but T53 remains engaged. When
operating in COF mode with the COF input active, it is possible to change fuel while the burner is in this
Continuous Pilot Standby state.
When fuel selection is changed, the MM moves to the restart position of the selected fuel, inhibiting the
burner from starting until the new position is reached.
Please refer to section 5 for full details about Continuous Pilot.
