If there is ever a problem with my onSiTE controller, will all my SiteStat thermostats keep operating my heating and cooling?
Yes. SiteStats are unaffected by any accidental break in communications with the controller. They keep operating your HVAC equipment as if no problem occurred. However, no schedule updates or control events (such as day/night setbacks, lights “on” at sunrise, etc.) will be sent to the thermostats or lighting fixtures until the onSiTE controller returns to normal operations.
