Oops, I guess I misread your post then. You said the click is coming from the A/C and it sounded like you were calling for heat with your single zone thermostat. I thought maybe you have a heat strip up above.
Is the click coming from the A/C, or the furnace.. or the thermostat? Or maybe the thermostat is actually located on the A/C?
The controls for the single zone are located in the A/C, and controls both the A/C and heater. The clicking is a common result of not initalizing the system and eminates from the A/C as that is where the control board is located. All the controls are low voltage. I don't know why it is "losing" it's initialization.
