Hello, just signed in after reading (2014) friendly discussion and advice on the CM721. I have a curious situation as follows:
Either fires up on Auto or Manual but not both. I switch the (Baxi HE A Range) boiler off then back on and it depends on which button I hit first - Auto or Manual - to fire up. I dropped the (portable) device onto a table while resetting before this situation arose; maybe that upset it. The whole system only installed last winter.
Hopefully it will behave adequately on Auto while I am away and leave the lodgers to it, hoping they don't mess it up!
