MXZ-4C Hyper-Heat

Re: Test Mode

The MXZ Hyper-Heat unit can be placed into Test Mode from the outdoor unit control board.

During Test Mode, the indoor units ignore the thermostat input and go to either full heating or cooling operation.

Activate Test Mode

SW-3, located directly above the LED display, has two "On/Off" dip switches.

Switch 1 = Cooling Test Mode

Switch 2 = Heating Test Mode

• On = Test Mode Activate
• Off = Normal Operation
