Turning the Unit On and Off

Important Verify the Base Controller On/Off Switch is turned on before turning on the HMI Control Panel. The Base Controller On/Off switch is located on the outside of the control box side of the unit.

If the HMI Control Panel is turned on and the Base Controller On/Off Switch is turned off, the HMI display screen will briefly show LOST CONTROLLER POWER. The HMI will then power down.

The unit is turned on by pressing the ON key and off by pressing the OFF key. When the ON key is pressed, the display briefly shows the THERMO KING Logo as the display initializes.

Note With extremely cold ambient temperatures, it may take up to 15 seconds for the display to appear on initial startup.
