“I currently have a Honeywell VisionPro thermostat that includes a interface module. The module sends only three wires to the thermostat... one of them is a C wire. Can this thermostat work properly using the existing three wire configuration???”

• Yes, as long as you are only controlling heat.

• I would check your furnace panel to be sure that wire is hooked up to power "C". I would assume you do not have A/C being controlled with this thermostat.
