WIRE TERMINAL FUNCTIONS
The table on page 70 shows how to wire to either a heatpump or
conventional system and explains the function of each terminal. Note that
the use of the O and W terminals vary depending on equipment type. The O
terminal drives the reversing valve for a heatpump but since that function
isn’t applicable for a conventional system, O becomes the first stage of
gas or electric heat. Similarly, W drives a single stage of strip heat in a
heatpump system but is used as second stage of gas or electric heat in a
conventional system.
