When connected properly, the Evergreen IM will operate following the same sequence of operation as the replaced motor according to the HVAC Systems demands and delays. Line voltage (115 or 230 VAC) is connected to the High Voltage POWER connections on the motor at all times. This voltage powers the microprocessor and the controls that drive the motor. However, the motor will only be driven when there is a communication demand on the Low Voltage and/or High Voltage Signal connections. The Low Voltage SIGNAL connections determine what speed the motor will operate at. This voltage alone cannot operate the motor. It can only communicate to the motor what level (speed) of operation is desired. The High Voltage SIGNAL connections are the on/off communication for the motor, as well as the determination of operational horse power

 

 

 

The temperature rise method can be used on fossil fuel furnaces; however, the Output BTUH must be confirmed by either adjusting the manifold gas pressure to the specification on the manufacturer’s data plate, or clocking the meter to confirm Input BTUH meets the manufacturer’s data plate listing.
