Designed for communications capabilities, the Glass Sentry Modbus is the ultimate solution for supermarkets and large c-store chains interested in typing the refrigeration system controls into a building automation platform. Parameters such as relative humidity, store temperature, dew point, frame temperatures, percent heater run time, hour watts saved, as well as alarm conditions can be viewed on a unit by unit basis. Perfect for the Corporate Energy Manager to evaluate site efficiencies and analyze systems from the convenience of his desk.

The Modbus feature is built into the Glass Sentry base unit that controls the operation of glass door heaters for walk-in coolers/freezers. Intelligence programmed within the microcontroller of Glass Sentry efficiently runs the heater circuit enough to keep condensation from occurring on the door frame and glass without wasting additional energy. By maintaining a temperature on the coldest spots on the door frame just a few degrees above the dewpoint, run time on the heater circuit can be reduced signifcantly.

- A two-sensor design for more accuracy in determining over-all frame temperatures both when the heaters are running and when they are not. This maximizes energy savings without creating headaches.

- A 30 amp rating so one unit can operate up to 16 doors without the extra modules and cost.

- Very small and discreet sensors.

- Simple wiring makes Glass Sentry a snap.
