Notes:
1 . Steps for optional accessories and modes not present in unit will be skipped.
2 . Economizer, Exhaust Fan, Power Exhaust Damper, Heat 1 & 2, Modulating Heat, Cool Valve, Reheat Valve, and Reheat Pumpout = with optional
feature.
3 . The exhaust fan will turn on anytime the economizer damper position is equal to or greater than the exhaust fan setpoint. It will not turn off until
the economizer damper position is at exhaust enable setpoint - 10% or lower.
(a) The condenser fans will operate any time a compressor is ON providing the outdoor air temperatures are within normal operating range.
(b) 27½ to 35 tons units have two stages of mechanical cooling. Both compressors run during cool stage two.
(c) The reheat pumpout output will be energized whenever the reheat circuit (circuit 2 for 40 to 50 tons) is energized for cooling operation.

Notes:
1 . 2 & 3 stage standard efficiency units: For Traditional VAV units, the VFD Command when “In-Control” will be controlled based on supply air
pressure requirements. For SZVAV units, the VFD command will be at discrete points during Test Mode.
2 . 2 & 3 stage standard efficiency units: For 27½ 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.
3 . 2 & 3 stage standard efficiency units: The reheat pumpout relay will be energized any time the reheat circuit is energized in active Cooling
Mode.
4 . 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.
5 . 2 & 3 stage standard efficiency units: Heating will not be energized during Service Test until the 6 minute VAV box ON timer has expired.
6 . 5 stage high efficiency units: Compressor 1 is the smaller compressor on the circuit.
7 . 5 stage high efficiency units: Condenser fans are controlled as defined for normal operation.
8 . 5 stage high efficiency units: Exhaust fan operates as defined for normal operation based on economizer position.
9 . 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.
