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.
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.
