Honeywell Home T4 1-Channel Wired Programmable Thermostat

Well suited to control combination boiler installations or additional zones in an S Plan Plus system

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. 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. Millions of people are still using outdated, complicated, inefficient thermostats to control their heating systems. The new T4 range of thermostats from Honeywell provides a simplified solution with effortless temperature control.
