Microprocessor Control

Test Outputs

When this feature is selected, the controller is effectively turned off. When stepping from one load to the next, the previous load is automatically turned off. The loads can also be toggled On and Off by selecting “ENTER.” Once turned on, the output will remain on for five minutes unless toggled off or the test outputs function is exited by selecting “MENU/ESC” (Compressor is limited to 15 seconds On to prevent damage.)

NOTICE

Risk of overheating the compressor during the Test Outputs mode. Can cause compressor damage.

Testing the compressor output for more than a few seconds can damage the compressor. Do not operate the unit in the Test Outputs mode any longer than is necessary for troubleshooting.

NOTICE

Risk of extended unit operation in the Test Outputs mode for troubleshooting. Can cause damage to unit.

DO NOT operate unit in the Test Outputs mode any longer than is necessary for troubleshooting

The outputs are as follows:

Normal Fan: Normal speed fan contactor

Humidifier: Humidifier contactor

Cool: Compressor contactor (Valve opens on chilled water units)

HGBP: Hot gas bypass valve

Reheat: Reheat contactor

Common Alarm: Common alarm relay

NOTE

Fan turned on with all loads.

Test Control Board

By selecting this function, the microcontroller will perform a self test lasting approximately 10 seconds. When the test is complete, the display will show the ROM checksum, ROM part number and firmware revision number.
