Bought to replace a failed programmable thermostat, the basic features offered by the Honeywell T4 were well understood.

In use the thermostat is working well and several of the new features have proved useful. Read full review

Honeywell T4 Room Programmable Thermostat.

Honeywell T4 RPT has various anti cycle modes, which in one of my installations is proving most useful. I expect it to greatly extend the life of the related Honeywell V4045? zone valve, which was cycled to failure twice by the previous RPT, without these features.Read full review

Good product from Honeywell.

Very easy to install if, like me, you are replacing an old timer/thermostat. Programming follows a fairly logical sequence and can be overridden if you prefer manual operation. It is Boiler Plus compliant to ensure current regulations are met.Read full review
