ECONOMISER2 PLUG

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 sensor or HH57A077 enthalpy sensor.

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