Hi Again.
My Uncle has a Horstmann H37 three zone programmer / timer.
These are fitted with a back-up battery.
The battery has a 10 year life and is "non-replaceable"
It has come to the end of it's life and now has to be reprogrammed after each power failure. To save expense (New programmer / rewire etc.), has anybody any information about the battery type or replaced one? We would rather not remove the programmer, have a look and then have to do it all again if possible.
Any information anybody?
Many Thanks.
Ian.
