Low Voltage Signal Connections
- (24VAC) Discrete Speed Operation
The Evergreen EM has 5 available speeds using 24VAC control inputs.
The inputs of the Evergreen can connect directly to the 24VAC thermostat
terminal strip or 24VAC signal outputs from the HVAC system control board.
1. Using a 1/4” Female Quick Connect Terminal and 22-18 AWG wire,
connect the (C) Common terminal on the motor to the 24VAC common
(C) thermostat terminal or 24VAC common side of the transformer on the
HVAC System. Make sure that this line is not connected to the side of the
transformer connected to the thermostat 24VAC (R). If it is connected to
the (R) high side of the transformer, the motor will not operate.
2. Select operating speeds by using 1/4” Female Quick Connect Terminal(s)
and 22-18 AWG wire to connect terminals (speeds) 1-5 to any 24VAC
thermostat demand or 24VAC HVAC system control board output.
DO NOT connect the Low Voltage SIGNAL (speed) terminals to the high
voltage power supply. Applying voltage above 30VAC to these terminals
will cause permanent damage to the motor.
