Below are examples of the low voltage wiring for Odyssey A2L air handlers and an electromechancial condenser(s).
Notes:
The 2 speed Electromechanical air handler (Model 15th digit = "C") operates with relays internal to the Relay Board. When you apply 24 vac to the G input on the J5 plug, the supply fan will start in low speed. The supply fan will go to full speed by additionally applying 24 vac to the Y2, W1, or W2 terminals. Constant volume operation can be obtained by setting the VFD parameter 4-12 Motor Speed Low Limit to match parameter 4-14 Motor Speed High Limit.
