normal unit operation to perform a check or test. For example,
the Pause mode display for a Shutdown alarm condition is
show below.
Pause Condition Display/Description
Phase Check “PAUSE CHECK”/During initial unit
start-up, the controller checks the power
phase sequence for correct compressor,
condenser fan and evaporator fan rotation.
Sensor Check “SENSR CHECK”/If the supply and
return air temperature difference is outside
certain limits during cooling and no alarms
are recorded, the controller performs a
Sensor Check test.
“SENSR XXX”/Shows the time remain-
ing on the current Sensor Check test being
performed.
Alarm Shutdown “PAUSE ALMXX”/Stops unit operation
due to a shutdown alarm condition. A 2-
digit alarm code (“XX”) appears in Pause

Typically the condenser fan continues to
operate while the controller attempts to
correct the condition and restart the unit.
The Pause mode display continues until the
shutdown condition has been corrected.
