2.3.6TD3 Temperature Display

The TD3 is a digital display unit designed to show both case temperature and product temperature for a refriger- ated store case or walk-in freezer. The TD3 mounts on the front of a case and connects to up to three input devices (a case temperature sensor, a product temperature probe, and either a defrost termination probe or thermostat). The real- time input values of these probes can be viewed on the TD3’s digital display by pressing the function button on the front panel to cycle through the temperatures.

The TD3 is connected to a central E2 RX controller via the Echelon Network. Input values are sent to the E2 from the TD3 for use in case circuit control.

A diagram of the TD3 layout is shown in Figure 2-22.

2.3.7Facility Status Display (FSD)

Figure 2-23- Facility Status Display

The FSD reports alarm information and more, (such as temperatures, occupancy, case status, and setpoints) and provides a centralized device for store personnel to review information by communicating with the E2 via Ethernet connectivity (minimum E2 firmware rev. 2.68F01).

The FSD has a touch screen color display for quick navigation and can be mounted in a separate, remote loca- tion from the E2 controller, which enables alarms and other relevant store information to be viewed from where it is most convenient for the user.

The FSD can be configured to filter out notices and/or return-to-normal alarms, and provides a quick review of all advisories and detailed advisory information. The FSD also receives alerts and provides annunciated alarms and alarm information directly to store and department manag- ers. This compact unit can be installed virtually anywhere with a standard Ethernet connection and 120V power source.

If more than one E2 controller is at a site, one E2 must be set up as the alarm annunciator for that site. The FSD will receive alarms from that alarm-annunciator E2 for the entire site. The FSD will point only to a single E2 at a site (it will not poll multiple controllers for alarms).

For more information, refer to the FSD Manual (P/N 026-1400).
