Wiring guide — Conventional systems

1. For the Honeywell TH9320WF thermostat installation, this thermostat requires a 24VAC common to power the unit. The K terminal is available for a C-wire adaptor (THP9045A1098).
2. Straighten the wire. Using a pen tip to hold down the terminal, gently slide the wire into the terminal hole.
