Setra Remote Monitoring Display
1.0 GENERAL INFORMATION
Thank you for purchasing the Setra Remote Monitoring Display (SRMD). The
SRMD is a digital panel meter with a bright 1” LED display for visibility at a
distance.
Before installing, please check the box and ensure the following items are
included:
Mounting Plate
Grommets for
Faceplate/Bezel
Faceplate/Bezel Engineering Unit Labels
Fi g. 1 .
1. Mounting Plate (with single or dual display in color(s) ordered:
green, red, or blue)
2. Faceplate Bezel (White or Metallic Finish, as ordered)
3. Engineering units label set
Note: If a dual display is ordered with a SRH temperature or humidity sensor and a color specified to match
each (or your own sensors), wire the correct sensor to the correct display.
The SRMD can be powered by 24 VAC/DC and can accept 0 to 5 or 0 to 10
VDC transducer signals from remote sensors. These field sensors can be temperature, humidity, CO2, etc.
2.0 INSTALLATION
2.1 Rough-In (see Fig 2.)
Install the SRMD in a 4 11/16” square electrical box. Run the power and signal
wiring into the box. Two wires are for the 24 VAC/DC power, and two wires are
for each of the signal lines from the field sensors to the display. For example,
the single display version would be 2 wires and the dual display needs 2 wires
for each of the two displays.
Run the wiring to the 24 VAC/DC source and to the sensors that are to be
monitored. The power to the sensors is not supplied by the displays.
2.2 Positioning the Front of the Electrical Box
It is very important that the box be set 1/16” to 1/8” below the finish wall so
that the faceplate will seal against the finished wall. If possible allow for ad-
justment at the finish stage to set the depth correctly.

3.0 WIRING TO THE DISPLAYS
Shown in Fig. 3 is a wiring diagram and picture of the back of the mounting
plate. Note that each display has a terminal strip. If you are using field sensors
that are not Setra’s SRH humidity/temperature sensors, then calibrate the display
according to Section 4 before completing the wiring shown here.
Input Wiring
Wiring:
+E - Excitation, 24 VAC
COM - 2 terminals connected together, wire
to 24 VAC and to common of the field sensor
+S - wire to the field sensor
