That thermostat should get power from 24V side of a transformer in the air handler. There should be a fuse in there on the PCB, but just as likely, there may be a 2-wire sensor in your drain trap that will shut it down if it senses water backing up in the drain piping. Clear that line from the outside of your house with a shop vac, cycle the breaker for the air handler if needed. You may also be low on freon, though, so a service call might be a good idea anyway.
