OPERATIONAL FEATURES

(Optional features may require additional components and/or sensors)

Sequential Load Activation: Time and temperature based logic that sequentially starts and stops stages of cooling

and reheat

Compressor Short-Cycle Control:Preventsexcessivecompressorwearbyusingrestartandanti-cyclelimits

Automatic or Manual Restart: Restart methods are programmable in the event of a power failure

Supplemental Compressor Operation during Energy Saver Mode:ExtendsthesavingsfromEnergySaverbyal-

lowingoneortwocompressorstosupplementthecoolingasneededwhenEnergySavercoolingisnotsufcient

Humidity Anticipation:Modiesthehumiditysetpointtoreduceexcesshumidicationanddehumidication
