Adjusting Damper Alarm Values
Upon receiving the alarm, the wall unit will remove
the “Y” call from the CCM, resetting the status of the
CCM. The alarm will stay present on the wall unit until
manually cleared. This operation has no configurable
parameters.
Economizer Damper
When the controller commands the economizer damper
actuator to a position other than 0% and the damper
switch indicates the damper is not open, after a delay
of 20 seconds (Open Del on display) the controller
will generate a damper failed to open alarm. When the
controller commands the economizer damper actuator
to the 0% position and the damper switch indicates
the damper is not closed, after a delay of 300 seconds
(Close Del on display) the controller will generate a
damper failed to close alarm.

Freezestat
When the coil temperature is below 30°F, the unit
will generate a Freeze alarm on the TEC-EYE
TM
and a
Freeze Temp alarm on the LC6000. This will operate
the blower and turn off the compressor.
When the coil temp is above 55°F, the alarm must be
reset with the TEC-EYE
