The flame will go out when power is removed from 
ignition control. The ignition control will turn off the 
gas valve and enter Standby Mode.

When Lockout Mode is entered, the ignition control 
will remove power to the gas valve, the igniter will 
turn off, the Lockout/Reset Light will turn on, and the 
Diagnostic LED will display the appropriate Error 
Code.

Lockout Mode is cleared by pressing an external reset 
switch for three seconds. The ignition control will 
clear all error codes and enter Standby Mode. During 
Lockout Manual Reset, the Diagnostic LED on the 
ignition control flashes red and orange, and the Reset 
Light remains on until the ignition control is reset. 
After the Reset Light turns off, stop pressing the 
switch. Holding the reset for three seconds after 
lockout has been cleared will cause a fault and result in 
entering Lockout Mode again. 

The following system tests are performed during 
normal operation. System tests are performed at a 
minimum of every 24 hours. 

If the voltage between terminals TH and GND on the 
control is below 18.75VAC +/- 0.75VAC for more than 
3 seconds the ignition control will turn off the gas 
valve and will not attempt to spark. The Diagnostic 
LED will display Error Code 5. The ignition control 
will not enter Lockout Mode if a low voltage condition 
is detected, but will enter Standby Mode and wait for 
the low voltage condition to be cleared.

If the voltage between terminals TH and GND on the 
control rises above 19.75VAC +/- 0.1VAC for at least 3 
seconds, the ignition control will then enter Start Up 
Mode.

Low Voltage Detection test is disabled during Run 
Mode.

The ignition control verifies that the gas valve is 
connected. Failure of this test results in the ignition 
control entering Lockout Mode with the Diagnostic 
LED displaying Error Code 2.

The Unexpected Presence of Flame test is performed 
when no flame is expected. Failure of this test results 
in the ignition control entering Lockout Mode with the 
Diagnostic LED displaying Error Code 3. 

During the Flame Monitoring test, the flame is 
checked to ensure the gas is being burned when the gas 
valve is on. Failure of this test will result in the 
ignition control entering Lockout Mode with the 
Diagnostic LED displaying Error Code 3.
