The Edge Pro ther-mostat can be set for 7-day, 5/2-day, or 1-day programmableoperation. Different heating and cooling set points and timesare programmable for 2 or 4 periods per day. The thermostatcan also be configured for non-programmable operation. Whenoperating as a non-programmable thermostat, the user will stillhave both temperature and humidity control.The Edge Pro thermostat has no need for batteries to storeuser-configured settings in memory. During power loss its in-ternal memory saves settings for unlimited time, and the clockcontinues to run for at least 24 hours.
