1PCS Industrial New and Original Yaskawa AC Servo Motor New 450W 3.8A SGMG-05ASRCS

 

Identify where on the HVAC system the PSC motor speed(s) were connected. These connections could be on a main circuit board, a separate fan control circuit board, or individual fan relay or fan switch. All of the connections previously used by the PSC motor speeds except Neutral will now be connected/wired together. This will allow the Evergreen motor to receive 115VAC communication from all HVAC system demands. NOTE: None of these connections will be energized at the same time by the HVAC system due to the fact that a PSC motor cannot be energized on more than one speed at a time. These 115VAC fan outputs will now become communication only for the Evergreen motor.

 

 

 

NOTE: In rare cases the (CF) tap on the circuit board is always powered when there is no heat or cool demand. In this case the customer has no control over the constant fan operation from the thermostat.
