10 Electronic Control & Alarms
IQ Touch™ Electronic Control Features
Replace Air Filter
When the "REPLACE AIR FILTER" LED is illuminated yellow, the air filter needs to be
replaced. The control will signal for air filter replacement after 3600 hours of operation.
After replacing the air filter, reset the air filter timer by pressing the AIR FILTER key for
3 seconds. The "REPLACE AIR FILTER" LED will be illuminated green for 3 seconds,
confirming a timer reset.
Control Lock
To disable the keypads on the control, begin by pressing the CONTROL LOCK key for
3 seconds until "LO" is displayed for 1 second. With the control locked, when keys are
pressed on the control panel, "LO" will be displayed. To unlock the control, press the
CONTROL LOCK key for 3 seconds. The display will show "UL" for 1 second.
Power Fail
The POWER FAIL indicator light informs you that due to a power failure, the cabinet
temperature exceeded 55ºF (13ºC). If the power failure lasted more than 1 hour, the
display alternates between showing the power failure duration (Hours and DURATION
LED illuminate in the display) and the cabinet temperature (ºF or ºC illuminates) every ½
second. This safety feature will aid in determining what food spoilage action to take.
The Power Fail indicator light and duration display can be turned off by pressing the
ALARM OFF key.
Alarms
There are 4 possible conditions that will cause the alarm tone to sound.
High Temp Alarm
If the temperature inside the cabinet exceeds 55°F (13°C), the HIGH TEMP LED
will illuminate, and after 1 hour, the HIGH TEMP Alarm will sound and the cabinet
temperature is shown in the display. The LED and temperature alarm will remain active
until the cabinet temperature is below 55ºF (13ºC).
The audible alarm can be turned off by pressing ALARM OFF key.
