Notes:2 & 3 stage standard efficiency units (excluding 40-50T Std Efficiency CV):
1. For Traditional VAV units, the VFD Command when "In-Control" will be controlled based on Supply Air Pressure Requirements. For SZ VAV units, the
VFD Command will be at discrete points during Test Mode.
2. For 27.5-35T 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.
3. The Reheat Pumpout relay will be energized any time the Reheat circuit is energized in active Cooling Mode.
4. 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.
5. Heating will not be energized during Service Test until the 6 minute VAV Box ON timer has expired.
Notes:5 stage high efficiency units (including 40-50T Std Efficiency CV):
1. Compressor 1 is the smaller compressor on the circuit.
2. Condenser fans are controlled as defined for normal operation.
3. Exhaust fan operates as defined for normal operation based on economizer position.
4. 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.
