Most thermostats only use the batteries to power the thermostat itself, LED display, programming, date/time, etc. Thermostats with a C wire (like yours seems to have), sometimes only use the batteries to remember your settings during a power outage.
What could be damaged if I shorted the your wire to?
(I actually jumped the R and G terminals but the G terminal was connected to the C terminal back at the HVAC). So I shorted it out, no? How bad might the damage be?
