fly boy3 Posted January 3, 2021 Share Posted January 3, 2021 Hi all, my ch programmer has died. Installed new batts, heating on, then suddenly the programmer readings dissapeared ? Strange thing is the heating is still,on with rads still hot. Suppose I need a new programmer. Quote Link to comment Share on other sites More sharing options...
John Wagg Posted January 3, 2021 Share Posted January 3, 2021 Try some more new batteries. Just in case there is a duff one in the unit. Also check the battery connections for corrosion. Is the programmer still working and it's just the readings that have disappeared ? Quote Link to comment Share on other sites More sharing options...
Geoff S Posted January 3, 2021 Share Posted January 3, 2021 I'd certainly try a different set of new batteries. Have you checked the voltage of each cell? Also contacts are the bane of multiple battery holders - check them for cleanliness, too. The batteries in my Brother label printer expired - 8xAAA. I had a load in stock I bought from eBuyer a year or so ago and fitted them and it still didn't work. I checked all the batteries in the packs and over 50% of them were either dead or very low. Fitting new ones that tested OK cured the problem and the label printer is back in action. I try to use Duracell primary cells where I can. Unfortunately it's so long since I bought the AAAs from Ebuyer I can't return them. I buy most of my PC related stuff from them and it's always been good but this was definitely a bad buy.

Martin Harris - Moderator Posted January 3, 2021 Share Posted January 3, 2021 Losing the display seems a common problem. Last time that it got to the point where my Tower Omnichron got to the point where it became unusable due to being unable to readthe display, I found a Hive wireless programmer/room thermostat/hub at a giveaway price (not much more than a replacement programmer) at Toolstation and fitted that to resolve the problem. The unit was perfectly functional except that I was unable to see which program was in use or make any modifications. I suspect that being installed subject to heat in an airing cupboard may often be the cause.

Simon Chaddock Posted January 3, 2021 Share Posted January 3, 2021 Of course you can always ditch the electronics and revert to a mechanical system. Just a synchronous clock, adjustable tabs and switches. Yes it has to be hard wired into the boiler so not as convenient but they are super reliable. Our CH boiler (its new) is controlled by a second hand one bought at a car boot sale over 20 years ago! Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted January 3, 2021 Author Share Posted January 3, 2021 Thanks lads, batts. tested ok, does seem that the display has dissapeared, but the rest seems to be working. The good news is that it still in the guarantee period by a few weeks. The local freindly plumber to give me a visit Mon pm. Cheers keep safe.

kc Posted January 4, 2021 Share Posted January 4, 2021 Programmers are often 'plug in' - a base frame is wired in and the control plugs in so it's very easy to change it yourself if you find the hidden screws top and bottom. Worth looking at what the plumber does so you can do it yourself in future. Quote Link to comment Share on other sites More sharing options...
