Rerad page #5 for compatibility http://www.hunterair.com/ssi/pdf/hun...ers-Manual.pdf

Most of the time a Hunter isn`t compatible with anything for very long,, if they work at all you will be lucky if its lasts 6 months,, get yourself a good Honeywell and forget the Hunter

From the manual "This thermostat is designed to work on the following heating and cooling systems:
Up to 2 Stage Heat/2 Stage Cool Millivolt Systems
Heat Only or Cool Only Systems 2-wire Hydronic Systems
Single and Multi-Stage Heat Pumps AC or Hard-wired
Gas, Electric or Oil Systems" this stat is compatible with a great many system and does work. However, I do agree, given a choice between Hunter and Honeywell, I' dprefer Honeywell but they both would work
