Auto Ignition Retry (Gas Models Only)
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.
Air Flow Switch Errors
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.
Airflow Switch Sensed Closed While Not In Run Mode
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.
Machine Errors
Airflow Switch Does Not Close After Cycle Started
If the airflow switch does not close within 5 seconds of the
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.
Airflow Switch Bounces During A Running Cycle
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.
Rotation Sensor Error
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.
