Hortsmann CentaurPlus C27 Programmer with Li-Ion Battery Back-Up 4.3 5 17 17
Works but firmare a bit buggy This is the new version which has replaced our defunct Centaur Plus timer which has worked flawlessly for many years till now. This new timer to all intents and purposes is exactly like our old one with a few tweaks here and there, like the welcomed addition of illuminated display. Unfortunately the firmware has also been tweaked, this now allows separate hour and minute time adjustments, which is fine. The central heating adjustments, which includes an advance facility, as the old unit did, works OK but, and this is where the problems started, the HW control works OK after being set up and controlled by the timer but there is a bug in the firmware that when setting the unit up and altering any of the settings for the hot water or setting the time for the clock the hot water comes on regardless of the present setting and will not go off until the next programmed 'off ' period, because I didn't want the hot water to be on all night I spent over an hour trying overcome this by altering set ' off ' times and the clock time, nothing worked so I ended up just turning the HW off using the tappet setting and switching it back to timed in the morning, it just wouldn't then come on in the morning but retained enough heat to be warm enough. At the time this was confusing and annoying but now it's working on timer all is fine, until I have the need to alter the time or the HW program and it will do it again. 11 Dec 2014
good programmer got this as I have used the same on another system. Does everything you would want and easy to set up. The last one is still good after ten years so expect the same from this 5 Dec 2014
Hortsmann control Controller on my oil fired heating system failed after around 15 years, so needed replaced after a search on the internet this product seemed to fit the bill, order it from Screwfix and was in the next day, removed the old programmer read the fitting instructions for the new on fitted it in approx. 30 minutes worked first time, changed the default programme to suit my need and showed my wife how to use it, therefore I have no problem recommending this unit and the services of screwfix. 3 Dec 2014
Simple to programme. I have fitted two of these units in the last week, I found them easy to programme, you can set daily 5 and 3 days or 7 independent day settings with easy over ride and boost facilities. I only gave 4 stars on performance and reliability because I haven't had time for a long term overview yet. 28 Nov 2014
