Honeywell T4R Wireless Thermostat

The Honeywell T4H (110A1021) and T4R (Y4H910RF4003) both offer a great heating solution for residential properties that have a combi boiler (recommended but not essential). Reviews are widely positive across the board. Of course, while being similar in many respects, even in appearance, they are two entirely different models, and as a result they have some slightly different features.

There is some confusion with this, as some people are not sure about the whole T4H / T4R model codes and have ended up buying the T4H (110A1021) thinking it was the wireless model. When in fact its the T4R that is the wireless model. The other big difference between the two is the price. The wired T4H comes in at around half the price of the T4R (wireless).

What else does the T4R have. There’s also the option of four on and off cycles per 24 hours, frost protection, manual override and away mode. As far as reviews go, as mentioned above they are widely positive, and most users reprt this model as being very easy to live with and works well. The warranty / guarantee length for this product is, I believe, 12 months from the date of purchase.
