    Maintains a stable temperature, this is helped by the cycling that can be setup in installation mode. For my old cast iron gas boiler I use the oil boiler cycle settings. Above the set temp the thermostat is fully off so no worries there. Likewise below the set temp the thermostat is fully on. Much better than my previous digital thermostat and the relay click some people complain about isn't that load. Anyway copper pipes make clicks as they expaned with heat. I set the ECO mode to 16 which has a countdown timer that I use while i'm at work, Well recommended!

    I replaced a standard manual controller with this digital one to improve control of our central heating. Excellent! It was a two wire fit and works really well, holding the rooms at a much more stable temp. than previously. One weakness is the switching noise (clicking) which is much more frequent and quite loud as it hunts about the set temp. more - but this is a small price to pay and if in a hall or outer room would not be a problem at all. The eco feature is brilliant - going out for an hour or two, just touch the eco button and it saves fuel!

    I have been looking for a digital thermostat to replace my old thermostat which was not accurate. This thermostat was very easy to install and very simple to use. It is very accurate and controls my boiler much better than the old unit. No more huge temperature over runs it keeps the room temperature within .5 of a degree which has reduced my oil consumption. This thermostat meets all the latest build regulations

    A great upgrade to our central heating system. The unit was a straight replacement for an old Honeywell mechanical stat. Just a two wire connection using the existing cable and no set up needed for our requirements. The job was done in less than 10 minutes. The house is now kept at a comfortable, even temperature, rather than the highs and lows of the old thermostat.

    Replaced failed mechanical room stats with Honeywell DT90E from PlumbWorld. Arrived on time, in perfect condition. Just installed them a day ago and they all work as intended - just beware that you get the wiring right for your situation, its not 100% clear so take care to match the wiring you have with the appropriate option in the instructions

    The product does everything it is supposed to do..and more. Once I had figured out the instructions, which were extremely difficult to understand, the actual installation was easy. Unfortunately, as I already have a programmer for my central heating system, I do not use the additional features of this thermostat

    The DT90E wired room thermostat has proved to be an ideal replacement for the previous electromechanical device. It advantageously avoids the unnecessary complexity of so many of the other products on the market, is very user friendly and easy to operate, and looks good.

    Purchased this to replace old dial thermostat. This is easy to fit and operate, has a lovely clear display and is much slimmer than the old one we had. Shows current temperature all the time and has eco setting too. Much cheaper at Plumbworld than other suppliers.

    Excellent product at a reasonable price and it was easier to install but, it would have been more nicer if the catelouge comes with more details on setting up.

    I replaced an older style dial-type thermostat with this one. It looks neat and tidy and appears to do its job - what more could I want?
