Horstmann Centaurstat 7 Room Thermostat is rated 4.6 out of 5 by 30.
Rated 4 out of 5 by from Good value thermostat I purchased this to replace the same model that has failed after 4 years. Will see how long this lasts, but given it is well priced for the features it has I consider it good value

Rated 4 out of 5 by from Very good controller Very happy with this so far. The timer functions work well. The only thing that stopped a full 5 out of 5 was one of the terminal screws broke when unscrewing it. Not an issue for me as im only using 1&2 so i was able to swap out a spare connector and put the sheared one in another slot. Yes, i could have taken it back for replacement, but for me, not worth the diesel for a connection thats not used.

Rated 5 out of 5 by from Easy install & set-up Replaced an old mechanical thermostat with this unit to allow us to set different temperatures over different periods of day/night, max. 6 different periods available in this unit. Also good to be able to see reading of actual vs set-point temperature. Very straightforward to install, designed to be wall mounted or over existing single/double gang set-in box and I happened to have an existing single gang box from the original stat to mount over (fixing centres the same). It was a simple changeover of the two wires into terminals on this new programmer, but I did check beforehand to make sure the existing stat was low volt/volt free and all the electrics in the house were isolated of course. I downloaded the user instructions from the Horstmann website and they seemed sligthly clearer to follow that the sheet that came in the box, but whichever you use it's very easy to set up and the copy function is great.

Rated 5 out of 5 by from Excellent room stat Replaced a manual Honeywell roomstat with this programmable one. Also replaced old analogue programmer with the Horstmann Centaur 27. They make a great pair. The two give total control of heating and hot water. Only gave 4 for performance as not sure how accurate the temperature is. They work well together and am sure they will provide the flexibility I need for the coming years. Got an electrician to connect them for me but both only took an hour.

Rated 5 out of 5 by from Working well I replaced a broken mechanical dial thermostat with this one. It was very easy to install. The only issue I had was tidying away and insulating unused wires from the previous install. As for the set-up of the device itself, following the instructions went well. Once I got the hang of it, it was also easy to amend the temperature ranges. This gives far more control than I ever had before. Its also nice to be able to see at a glance the current temperature. Overall, I am very happy with the product. Can't yet talk about reliability - as it has only been operating for one month.

Rated 5 out of 5 by from Excellent digital thermostat My old Honeywell thermostat was working fine but I wanted more control over temperature day by day. This replacement was a doodle to fit and after a bit of planning ( times and temps) easy to set-up. After 3 or 4 weeks use I now have it tuned to perfection and I am really pleased with it. Running controls are simple ( override up down or lock) . (Hope it lasts as long as the Honeywell which must be 25+ years old)

Rated 5 out of 5 by from Excelent Thermostat This is the second unit I have bought, for another house. It offers great flexability with day by day programming as well as immediate change by touching the plus or minus buttons you can change the set temperature until the next time slot. Simple and effective, and at a good price.
