2.3.5 TD3 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 Echelo
n 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.

2.3.6 Facility 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
nav
igation 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
ret
urn-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
wi
th 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).
