    PHASING ® Predator units are properly phased at the factory. Check for proper compressor rotation. If the blower or compressors rotate in the wrong direction at start-up, the electrical connec- tion to the unit is misphased. Change the phasing of the Field Line Connection at the factory or field supplied discon- nect to obtain proper rotation.

    COOLING SEQUENCE OF OPERATION CONTINUOUS BLOWER By setting the room thermostat fan switch to "ON," the supply air blower will operate continuously. INTERMITTENT BLOWER With the room thermostat fan switch set to "AUTO" and the system switch set to either the "AUTO" or "HEAT" settings, the blower is energized whenever a cooling or heating opera- tion is requested.

  • Page 35: Cooling Operation Errors

    035-17311-003-A-0704 COOLING OPERATION ERRORS Each cooling system is monitored for operation outside of the intended parameters. Errors are handled as described below. All system errors override minimum run times for compres- sors. HIGH-PRESSURE LIMIT SWITCH During cooling operation, if a high-pressure limit switch opens, the UCB will de-energize the associated compressor, initiate the ASCD (Anti-short cycle delay), and, if the other compressor is idle, stop the condenser fans.

  • Page 36: Flash Codes

    a compressor too soon after its previous run. Additionally, a minimum run time is imposed any time a compressor is ener- gized. The ASCD is initiated on unit start-up and on any compressor reset or lock-out. FLASH CODES The UCB will initiate a flash code associated with errors within the system.
