Notes:
1 . The IGV/VFD will be controlled to the supply pressure setpoint unless test mode has been running for six minutes or longer. After six minutes, the
IGV damper will be allowed to drive to 100% for step nine and ten.
2 . 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 the exhaust enable setpoint - 10% or lower.
3 . The VHR relay output will be energized at the start of the test mode to allow time for the VAV boxes to open. It takes six minutes for the boxes to
drive from the full closed position to the full open position. The timing cannot be changed in the field.
4 . Economizer, Power Exhaust Damper, HT1, HT2, Mod. Heat, Cool Valve, Reheat Valve, and Reheat Pump Out = with optional feature
(a) 27½ to 35 (On), 30 to 50 (Off)
(b) 27½ to 35 ton units have two stages of mechanical cooling. Both compressors run during cool stage two.
(c) The condenser fan will operate any time a compressor is ON providing the outdoor temperatures are within normal operating range.
(d)
The supply fan will not be allowed to go from an off state to an on state until the IGV are fully closed.
(e) The heat outputs will not be allowed to come on until the unit has been in test mode for at least six minutes and the IGV/VFD is at 100%.
