If You Need Service Your Energy Sentry Model 9212 has been carefully assembled and tested at the factory in Loveland, Colo- rado, USA. Only components having high reliability and long life have been used in its manufacture. In the event that a failure does occur, your 9212 has been designed so household appliances and loads will con- tinue to function.
As this limit is approached, the demand controller. As the demand approaches the Energy Sentry Controller begins shutting off pre- demand limit, the demand controller uses the priority determined loads to control peak demand.
