proper operation.
• If a valve is present, check for proper operation.
• Check burner adjustments (refer to burner manufacturers instructions) and spark was not
detected.
• Check the cad cell positioning and clean the eye.
• Expose the cad cell to ambient light (generally enough light to read by is adequate)
— If the LED does not turn on, short the cad cell terminals,
— If the LED does not turn on, replace the control,
— If the LED turns on, replace the cad cell.
• Shield the cad cell from light.
— If the LED does not turn off, unplug the cad cell,

• Supply voltage was low to the control or a communication error has occurred.
• Remove all devices from the EnviraCOM™ connections, 3-pin plug and screw terminals
"1-2-3".
— Measure the voltage across screw terminals "2" and "3"
If it's between 22VAC and 30VAC and the error does not clear, replace control.
— If it's outside that range, review appliance wiring. There should be approximately 24VAC
across "2" and "3".
An error has been detected inside the control. Replace control if the error persists.
