Replaced Batteries
We just replaced the batteries to our thermostat and the information pad has not returned to display the normal data that it usually shows (current temperature, etc.) and still shows the "REPL BATT" signal.
Does it take awhile to calibrate or is there something else that I must to do reset it?
