Honeywell Home T6 Wired Heating & Hot Water Smart Thermostat (427PR)

Integrates with any boiler and any system, including combi boilers, OpenTherm and heat pumps. Also works with zone valve applications but not with electric heating (240V). Touchscreen technology makes scheduling, changing and overriding temperatures easy and the Honeywell Home app gives complete control over home heating, including schedules and automated synchronisation with the thermostat. 2-channel wireless receiver for control of heating, hot water or 2 heating zones (an additional thermostat is required). Uses the smartphone location feature to communicate with the app to determine when a property is vacant, or when a user is on the way home, adjusting the temperature automatically. Features a choice of schedule settings including 7 day, 5/2 day and single day scheduling with up to 6x different time settings per day. 'Apple Home Kit' ready, meaning it can be controlled using an Apple device (requires iOS 8.1 or later), as part of a suite of home kit compatible products. Professional installation recommended.

Rated 3 out of 5 by from Good device, problems with app I bought this from Screwfix 18 months ago and after 14 months finally got an electrician to fit it in Aug. 2021. This is my first winter of operating it from 3,000 miles away. The functionality of the thermostat itself is fine, but I've had some problems with the Honeywell Home app on android that controls it. If you look for app reviews on the app store you will find pages of negative comments from frustrated and disappointed customers. In fact many pages of bad comments get added every month. Unlike many of those folks, I got connected to the device without a problem, and connectivity seems reliable. But from time to time the device won't accept my manual adjustments. It's running fine this week, following my pre-set schedule. But last night when it was snowing I tried to override and turn the heat up. The app appears to accept the new temp, but then flips back to the pre-set temp after 20 seconds or so. Today that issue is resolved and it's accepting my temp adjustments no problem. It's not a wifi problem as such as the app is reporting the scheduled temp changes in a timely accurate way. It's as if the thermostat transmits to the app but does not received instructions. Bottom line, you should read the many terrible reviews of the Honeywell Home app before you buy this device.

Can one of the zones be used for underfloor heating?

Receiver box

Can you connect this to an old wireless receiver box?
Asked by: Hannahvlc
Hi, This cannot be used with any other receiver than the one provided. I recommend that you have a professional install a thermostat like this so it can be set up and connected correctly.
