Electronic Controllers
Vaughn has been designing and programming streamlined and sophisticated energy controllers in conjunction with electric utility thermal storage programs for over 30 years, satisfying the utility's need for peak control while also offering a great deal of flexibility for the end user. Programs for the EC are determined by the electric utility. Once programmed, the EC automatically controls the water heater, saving energy without any worry or inconvenience to the homeowner. If for some reason the homeowner wishes to override the system, an override may be accomplished with the simple push of a button. Vaughn's gateway neutral, high performance control devices can accomodate any number of programs to suit nearly any application.

Cellular Interface
General Specifications | |
---|---|
Dimensions | 5.25" H X 3.25" W X 1.25" D |
Weight | 4 oz. |
Voltage | 12 |

Similar to the WiFi Interface, the cellular interface serves as a remote communication supplement to the existing, dedicated program schedule. Cellular transmissions typically are only to be used to ativate events outside of the default program, such as unanticipated load shifts or changes to off-peak schedules.
ZIGBEE/Bluetooth Interface
General Specifications | |
---|---|
Dimensions | 2.0" H X 1.0" W X 0.5" D |
Weight | 4 oz. |
Range | 100 yards |

Similar to the WiFi Interface, the ZIGBEE/Bluetooth interface can be used to communicate to local devices such as a meter. Typically, communications are only to be used to activate events outside of the default program, such as unanticipated load shifts or changes to off-peak schedules.
- Data logging
- Reprogramming
- Variable frequencies
- On-site updates
ZIGBEE/Bluetooth Controller
General Specifications | |
---|---|
Dimensions | 2.0" H X 1.0" W X 0.5" D |
Weight | 6 oz. |
Voltage | 12Vdc |
Wattage | 0.5 W |
Approvals | FCC (USA), IC (Canada) |

The ZIGBEE remote mimics the functionality of the EC unit buttons, allowing for external changes to the set program as well as implement overrides and vacation settings.
- Factory programmed
