2 & 3 stage standard efficiency units: For 27.5 to 35 ton units, both compressors will be energized during the Cool 2 Step. For 40-50T units,
only Compressor 2 will be energized during the Cool 2 Step.
2
.
2 & 3 stage standard efficiency units: The reheat pumpout relay will be energized any time the reheat circuit is energized in active Cooling
Mode.
3
.
2 & 3 stage standard efficiency units: For units with Statitrac™ installed, the exhaust damper will track the Economizer position during
Service Test Mode and the Exhaust Fan will be energized once the economizer rises above the exhaust enable setpoint.
4
.
2 & 3 stage standard efficiency units: Heating will not be energized during Service Test until the 6 minute VAV box ON timer has expired.
5
.
5 stage high efficiency units: Compressor 1 is the smaller compressor on the circuit.
6
.
5 stage high efficiency units: Condenser fans are controlled as defined for normal operation.
7
.
5 stage high efficiency units: Exhaust fan operates as defined for normal operation based on economizer position.
8
.
5 stage high efficiency units: When compressor 1 is energized with either C1, C2, or with both for 30 minutes continuously, C3 will be
required to de-energize for 30 seconds.
