WIFI Thermostat

[Shane]

Hi Guys. I have a customer that want to put in a wifi smart themostat, They only have 4 wire to the current stat ( Black red green white) They want the new honeywell stat, Any ideas on how to hook this up without pulling new stat wire through the house? or possibly another brand that would work?

Thanks

Shane

Buy the Honeywell THP9045 Wiring Module,

What kind of model of Honeywell thermostat are they using?

This module works with certain Homeywell thermostats.
