If the Ignition Control Module (ICM) fails to ignite the 
gas valve the ICM will send an ICM Lockout Alarm to 
the control. When the control receives the ICM 
Lockout Alarm it will increment the ICM Lockout 
Alarm audit counter. When the error becomes fatal 
(user input needed to restart the machine) the control 
will increment the Heat Error audit counter and record 
the Heat Error in the Last Eight Alarms Menu.

If the ICM needs to be manually reset, when the 
control receives the ICM Lockout Alarm it will 
display the Cycle Stopped Menu with text prompting 

the user to press the

keypad to reset the ICM. 

The user can continue to reset the ICM until there are 
no more programmable retry attempts (factory default 
is 3) or the gas ignites. On machines equipped with an 
ICM that does not need to be manually reset, when the 
control receives the ICM Lockout Alarm it will turn 
the heat relay off for twenty (20) seconds and then turn 
it back on to try and ignite the gas. The control will 
continue to try and ignite the gas until there are no 
more programmable retry attempts (factory default is 
3) or the gas ignites. If the ICM fails to ignite the gas 
on the last attempt the control will start the Cool Down 
portion of the cycle, display the heat error message 
and sound the audio signal. When the Cool Down 
portion of the cycle ends the control will continue to 
display the error message until power is cycled to the 

machine or a user presses the

keypad.

The control will flag an Airflow Switch Error under 
several conditions. Airflow Switch Errors will be 
processed differently depending upon what state the 
machine was in when the error was detected.

If an airflow switch is sensed closed 30 seconds after 
entering Idle Mode, or End of Cycle Mode, the control 
will display an error message until power is cycled or 
the error clears. The cycle will not start and all user 
inputs will be ignored. If the error does clear, the 
control will go back to its previous mode of operation. 
When this error occurs the Airflow Switch 1 error 
counter will be incremented and the error will also be 
saved to the Last Eight Alarms Menu.

If the airflow switch does not close within 5 seconds 
of the start/re-start of a cycle, the control will go to the 
Cool Down portion of the cycle, display an error 
message and sound the audio alarm. Once the Cool 
Down portion of the cycle ends, the control will 
continue to display the error message until the power 

is cycled to the machine or the

keypad is 

pressed. When this error occurs, the Airflow Switch 2 
error counter will be incremented and the error will 
also be saved to the Last Eight Alarms Menu.

If the airflow switch is open for at least one second, 
the heat will be turned off and will remain off until the 
switch is observed closed for at least 5 seconds (it is 
flagged as an airflow switch bounce). If there are 5 
airflow switch bounces within 5 minutes the control 
will go to the Cool Down portion of the cycle, display 
an error message and sound the audio signal. When the 
Cool Down portion of the cycle ends, the control will 
continue displaying the error message until power is 

cycled or a user presses the

keypad. When this 

error occurs, the Airflow Switch Bounce Error will be 
incremented and the error will also be saved to the 
Last Eight Alarms Menu. The Airflow Switch Bounce 
counter will be incremented for every instance of an 
airflow switch bounce.

If the machine is equipped with a rotation sensor, the 
control will constantly monitor the input and calculate 
the cylinder’s rpm. If the rpm drops to zero while the 
cylinder is supposed to be spinning, the control will go 
to the Cool Down portion of the cycle. The control 
will display an error message and sound the audio 
signal. Once the Cool Down portion ends, the control 
will continue to display the error message until power 
is cycled to the machine or the correct keypad is 
pressed. This error will increment the Rotation Sensor 
Error counter and will be saved in the Last Eight 
Alarms Menu.
