To test the Beacon board place the test jumper to the “TEST” position. The board will then cycle through each output for 10
seconds. It will energize and de-energize the fan motor, electric heater, expansion valve and compressor for 10 seconds. When
in the TEST mode the status light flashes quickly. If a sensor is bad it will flash per the error chart. AT THE END OF THE TEST
RETURN THE JUMPER TO THE NORMAL POSITION.
