Operating Instructions
40
The four “soft” keys under the display are
multi-purpose keys (Figure 11). Their function
changes depending on the operation being
performed. If a soft key is active the key function
is shown in the display directly above the key.
The keys are numbered from left to right, with
Key 1 on the far left and Key 4 on the far right.
Typical soft key applications:
Display Heater
The HMI control panel is equipped with a display heater. This
heater is needed to make the display visible in cold ambient
temperatures.
The HMI has its own internal temperature sensor for the
display heater. The heater is energized when the unit is turned
on and the ambient temperature is below 29.4°F (-2°C). The
heater turns off when the temperature sensed by the internal
sensor rises above 37.4°F (+3°C). The heater draws from 1.4 to
1.7 amps when energized.
The colder the ambient temperature the longer it will take for
the heater to make the display visible on a cold startup. It may
take 10-15 seconds for the display to appear with very cold
temperatures
Turning Unit On and Off
The unit is turned on by pressing the ON hard key (Figure 12)
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 Multi-Temp applications, Zone 1 is turned on
any time the host unit is turned on. Zone 1 is turned off when
the host unit is turned off.
NOTE: With extremely cold ambient temperatures it may
take up to 15 seconds for the display to appear on initial
startup.
