The Honeywell Y87RF Single-Zone Connected Thermostat allows you to remotely control room temperatures from a smart phone or tablet (home or away).

You can use it as a portable wireless thermostat that will control your single zone heating system based on the temperature of the room it's located in (move it around your home to where you're actually sitting). Or use it together with the Honeywell Mobile Access Gateway and you can control the temperature from your smartphone or tablet whether your at home or away.

The Single-Zone Thermostat can also be used with the Honeywell evohome multi-zone system as a wireless wall thermostat.

  • Wireless Digital Room Thermostat
  • Use it as a portable thermostat to control the heating anywhere in your home
  • Control your heating from a smartphone or table
  • Can be used within a evohome system

    • Battery powered wireless operation with low battery indicator and pre-bound to the wireless relay (included).
    • Connect to the internet using the Honeywell Mobile Access Kit.
    • The wireless relay can be wired directly to boilers, motorised zone valves or actuators.

Feels cheap and flimsy
Just installed it for one of our customers. The whole thing is made out of plastic and the outer ring feels quite flexible, which makes me wonder how long it will last. On the other hand it is easy to install. If you like to connect to smartphone or internet you will need additional product
