NOTES:
1. Switch on actuator must be in run position for economizer to operate.
2. PremierLink™ control re
q
uires that the standard 50HJ540569 out-
side-air sensor be replaced by either the CROASENR001A00 dry
bulb sensor 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 set point.
† 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).
