Horstmann DRT2 Programmable Digital Room Thermostat is rated 4.1 out of 5 by 29.
Rated 4 out of 5 by from Value for money A basic programmable thermostat that does everything that most people need at a very good price. Easy to install and program. Change the batteries once a year and you will have no problems but you only have a few seconds to install the new batteries before the current program is lost. Make sure that the new ones are in your hand ready.

Rated 5 out of 5 by from Simple to use andfit We had been looking for a battery operated programmable CH timer for a while, and found this one which was easy to install and easy to programme, very, very impressed with it.

Rated 1 out of 5 by from Too complicated for home use Good features, but complicated to program, with tiny display and made worse by hopeless documentation. There is no mains power, and it looses its entire program when the batteries are replaced and so needs setting up from scratch. Does nothing useful until reprogrammed. Very disappointing product from a big rich company that can and usually does make better products.

Rated 5 out of 5 by from Best product for the price This thermostat is by far the best value for money product on the market and Screwfix offer it at the best price I could find. It is very easy to install and has enough features to provide very good overall flexible control that is needed to keep your home warm and cool when you need it to.

Rated 4 out of 5 by from Horstmann DRT2 I bought this to replace the previous model which stopped working after a couple of years use. For the price, it cannot be beaten as it's packed with features and is simple to install. The build quality of the device is a bit questionable and I dare say the componentry is cheap but it is what it is. Beware when installing, I found the wiring diagram in the instructions and and the back of the gadget to be incorrect. Follow the label on the terminals to wire correctly. This differs from the instructions. Would I recommend this product? Yes I would on price and features.

Rated 5 out of 5 by from Horstmann DRT2 Programmable Di This product far exceeded my expectations as i have bought considerably more expensive stats in the past. This one is easily on a par with any previous units I have installed in the past, would definitely purchase again.

Rated 5 out of 5 by from Fanstatstic You wont get a programmable room stat with this many features and this reliability for this price anywhere else. 2 or 3 wire installation and relatively simple to program a must for every new combi install, I have fitted many and have one in my own house.

Rated 4 out of 5 by from Good value programable stat The product is what it is - a simple programable room thermostat which is straightforward to fit as a replacement and easy to set up and use. Unfortunately I couldn't get it to work out of the box and it took me a few minutes to realise that one of the supplied batteries was dead. After that, no problems. I'd trust the Horstmann brand and the best price I could find anywhere was from Screwfix. As I've only had it two days, I can't speak for reliability but as it's very basic electronics I imagine once it's running it will stay running.
