TERMINAL DESIGNATION<br />
IGN/120 – 120 volt supply for Hot Surface Igniter (only when supply is 120 volts)<br />
IGN/240 – 120 volt supply for Hot Surface Igniter (only when supply is 240 volts)<br />
L1 – (black wire) Line supply voltage to module (120 volts)<br />
L2 – (white wire) Line supply voltage to module (neutral only if heater supplied by 120 volts)<br />
IGN – (white wire) 120 volt output to Hot Surface Igniter (only when heater firing)<br />
FS – (white wire) 24 volts to flame rectifier (constant). This is a communication wire there will<br />
be signals sent in both directions on this wire (24vac to the sensor 7 Micro amps returning).<br />
TH – (white wire) 24 volts from Low Pressure Switch (fan)<br />
VAL – (red and blue wires) 24 volts to open gas valve<br />
Only the blue wire is used by the gas valve even though both have been energized.<br />
GND – (white wire) 24 volt ground<br />
