Hello Mike here.
I could really do with some help wiring in a Honeywell cm927 into a remeha avanta plus 28c. I know this is really easy but I'm a bit new to the game and just needed a bit of help so I can move on with my career. Do I leave the current mechanical timer connected into x2 . And do the AB wires from receiver go to 7 and 8 on x9?.
Right I have to assume here that this is in a rented property (?) or is family as you refer to them as 'they' however, there is a replacement digital timer available for this model link follows or you could buy this on ebay which also throws up a spare pcb - http://www.ebay.co.uk/itm/Remeha-Avanta-Plus-28c-PCB-And-Control-Panel-/121644232148?pt=LH_DefaultDomain_3&hash=item1c528fadd4 for the same price.

Remember the thermostat only controls the temperature not the time and whilst switching it on manually controls the time if you forget to turn it off then you use up gas. Also (I assume here too) if you are a landlord you have a duty to provide working heating systems both time and temperature. But at least you have some suggestions as to a way forward ~ Ian
You can sent it my email address if you like ~ dales.electronic(at)btopenworld.com and I'll pick it up when I get to work tomorrow. Basically if you
get a base station that plugs into the connections already mentioned then a wireless one would work fine for you but you would have to be aware that the batteries would need changing from time to time.
Give me an hour and I will be back on here, just heading off to pick my daughter up
