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

2-wire installation only

A separate interface module must be ordered for this job as it is a 2-wire connection only. Don't think you can just trade it in for yours. If you need this one they sell another item that comes with this thermostat, interface module and 3 sensors. It's a lot cheaper than buying them individually.

Pros
  • Red LINK Wireless
Cons
  • Small parts

Poor quality product keeps dying

This product keeps breaking. I've gotten 6 of these in the last 2 years for about $250 each and they only last 1 to 9 months.

Pros
  • Precise temperature control (+/- 1 degree Fahrenheit) for reliable and constant temperature
Cons
  • Expensive
