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
