Rated 5 out of 5Â by Onion Danfoss beats Drayton !
I've just replaced my Drayton Digistat 3+ with the Danfoss TP5000Si and what a difference!! Previously the Drayton device gave such a wide temperature variation that I got endless complaints from the family who would generally be too hot or too cold, depending on what mood the programmer was in. Apparently this is due to the algorithms which are built into the device to allow it to learn all about the characteristics of your house so that it could provide efficiency and cost saving. Sorry, I gave it a year and it was still trying to get to grips with the house ... and all I wanted was a device which provided the right temperature at the right time. And the Danfoss was the answer. (Note - it also has a built-in learning algorithm, but it can be disabled, so that you get the precise temperature control you're looking for). Highly recommended and easy to install.

Best on the market, easy to fit and easy to use, if you fit one of these you will not fit anything else.
