data, status, and alarms.
The CORE Unit Controller is an input and output junction
point. If in the thermostat mode, thermostat inputs at P297
result in an output to unit components. If the heartbeat LED
isnotashing,see”Table1.LEDOperationIndicators”on
page 5 for heartbeat operation. If the display shows
an alarm. If the thermostat input indicating lights are not
responding appropriately, check the thermostat or a DDC
control acting as thermostat inputs into P297.
Basic cooling and heating functions may be energized to test
major unit components by using the CORE Unit Controller
testing function or by using jumper wires on the Field Wiring
Termination plug P297.
