NOTES:

1.Switch on actuator must be in run position for economizer to operate.

2.PremierLink™ control requires that the standard 50HJ540569 outside-air sensor be replaced by either the CROASENR001A00 dry bulb sen sor or HH57A077 enthalpy sensor.

3.50HJ540573 actuator consists of the 50HJ540567 actuator and a harness with 500-ohm resistor.

*For single enthalpy control, the module compares outdoor enthalpy to the ABCD setpoint.

†Power at N terminal determines Occupied/Unoccupied setting: 24 vac (Occupied), no power (Unoccupied). ** Modulation is based on the supply-air sensor signal.

†† Modulation is based on the DCV signal.

*** Modulation is based on the greater of DCV and supply-air sensor signals, between minimum position and either maximum position (DCV) or fully open (supply-air signal).

††† Modulation is based on the greater of DCV and supply-air sensor signals, between closed and either maximum position (DCV) or fully open (supply-air signal).
