Review on 🌑️ Honeywell THX9421R5021WW: Revolutionizing Thermostat Technology with Definition by Andrew Grant

Revainrating 5 out of 5

2-wire setup, EIM and wireless sensors all separate

This thermostat is a commercial 2-wire device used to control heating, cooling and humidity , dehumidifier and ventilation. Wireless sensors and Redlink Gateway will work with this thermostat, sold separately.

Pros
  • Control heating, cooling and air quality devices with just 2 wires on one thermostat
Cons
  • Questionable purchase for the elderly
