Description Purpose
SOLENOID 1 Connection from Solenoid 1 to main electronics. Enables powering of solenoid.
SOLENOID 2 Connection from Solenoid 2 to main electronics. Enables powering of solenoid.
PROOF OF CLOSURE
POC 1 Connection from Solenoid 1 POC to main electronics. Tied to the valve interface
Open and Closed LEDs. Refer to
POC 2 Connection from Solenoid 2 POC to main electronics. Tied to the valve interface
Open and Closed LEDs. Refer to
FUEL/AIR Module that measures gas, air and gas/air mix inputs from fuel/air system to
control the fuel/air premix valves. Works with stepper MOTOR.
MOTOR Stepper motor performs valve modulation in response to changing conditions from
the fuel/air module and burner system
