Hi Mark! The THP9045A Wire Saver Module can work with the Honeywell - Smart Color Thermostat with Wi-Fi Connectivity - Silver. This module will allow this thermostat to have a common wire needed to power the thermostat. The module will come with instructions to install with our WiFi thermostats. Have a great day!
