ACTUATOR
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).
