Upgraded a 12vac to 24vac z-wave thermostat for A/C unit also adding transformer??? Answered
I decided to install a Z-wave Thermostat after an old ordinary one failed to work, It worked fine with home automation and all, apart from it being 24vac thermostat but receiving only 12vac from the motherboard (I was forced to change the batteries every 3 months),
To make life easier (and not have to change batteries) I ended up doing the stupid thing tying to Upgrade from 12vac to 24vac adding a transformer, it worked fine for the first 5 mins and then stopped, it was then that I realised I may have overloaded the mother board,
My question is, is there a quick fix for this? or do I have to replace the whole motherboard?, if so which one?
