My thermostat lost connectivity last night. I restored connectivity at 1am, just by waliking over to the thermostaat with my phone. It was working fin all day, but now it doesn't work again. "Rc" error, though nothing was changed in the wiring. I took it off the wall, and now when I reinserted it into the base, it isn't working at all. It's not even lighting up. I am in Florida, and it is hot here. I need the A/C to power up again. Please help!
