What are RS Room Sensors?
RS sensors are thermistor-based temperature sensors used with any control module that
connects to the Rnet such as an LGR, ME-LGR, SE line, ME line, ZN line, or WebZone
control module. The four types of RS sensors are RS Standard, RS Plus, RS Pro, and RS
Pro-F.
An Rnet can consist of any of the following combinations of devices wired in a daisy-chain
or star configuration:
•
1 RS Plus, RS Pro, or RS Pro-F
•
1–4 RS Standards
•
1–4 RS Standards, and 1 RS Plus, RS Pro, or RS Pro-F
•
Any of the above combinations, plus up to 2 BACview's, but no more than 6 devices
total
NOTES
○
If you use two BACview's, one can be powered by the Rnet, but the other must be
externally powered.
○
ZN line control modules do not support BACview6’s.

To address an RS
Standard
The default address of an RS Standard is 1. The first RS Standard retains this address. To
change the address of each additional RS Standard on the network:
1
Pull the back plate off the sensor, pulling from the bottom first.
2
Remove the two hexagonal screws that attach the circuit board to the cover plate.
3
Remove the cover plate.
4
On the circuit board, set the address jumper to 2, 3, or 4. Each sensor must have a
unique address on the Rnet.
5
Attach the circuit board to the cover plate with the hexagonal screws.

the RS sensor microblock's Properties page in WebCTRL.
MANUAL ON
button
Press the MANUAL ON button one time to override the schedule and set the zone to
occupied for the amount of time defined in the Each pulse field on the RS sensor
microblock's Properties page in WebCTRL. Press the button again to incrementally
increase the time. For example, if the Each pulse field is set at five minutes, press the
button once for an occupancy of five minutes, twice for ten minutes, and so on. The
maximum length of time you can override the schedule is defined in the Max Accum field
on the Properties page.
To cancel the override, hold down the MANUAL ON button until the OCCUPIED LED turns
off.
OCCUPIED LED
The OCCUPIED LED lights when the zone is occupied from a regular schedule or a manual
override.

Display
The display shows occupancy, zone temperature, and an alarm bell icon. Celsius values
are to the nearest 0.5 degree; Fahrenheit values are to the nearest full degree.
The display shows Occupied when the zone is occupied from a regular schedule or from a
manual override.
MANUAL ON
button
Press the MANUAL ON button one time to override the schedule and set the zone to
occupied for the amount of time defined in the Each pulse field on the RS sensor
microblock's Properties page in WebCTRL. Press the button again to incrementally
increase the time. For example, if the Each pulse field is set at five minutes, press the
button once for an occupancy of five minutes, twice for ten minutes, and so on. The
maximum length of time you can override the schedule is defined in the Max Accum field
on the Properties page.
The display shows the duration of the override in minutes. If the override time exceeds
199 minutes, the display shows the time in hours.
To cancel the override, hold the button down until 0 displays. Wait five seconds for the
display to show the current zone temperature again.

WARMER and
COOLER buttons
To raise or lower the zone's setpoint:
1
Press WARMER or COOLER to display the current average setpoint (the average
between the heating and cooling setpoints).
2
Press WARMER or COOLER again to raise or lower the setpoint. You can adjust the
setpoint by no more than the amount defined in the Max Adjust field on the RS sensor
microblock's Properties page in WebCTRL.
NOTE Pressing WARMER or COOLER will override an unoccupied schedule and set the
zone to occupied for the amount of time defined in the Each pulse field on the RS sensor
microblock's Properties page in WebCTRL.

Local access port
The RS Pro-F has all the features of the RS Pro (page 5) plus the additional functionality
described for the following four buttons.
NOTE Much of the RS Pro-F's functionality depends on the setup of the RS Zone Sensor
with Fan Control microblock in EIKON for WebCTRL. See the system engineer for
instructions on using these four buttons.
MANUAL ON
button
The Timed Local Override section of the microblock dialog box determines if pressing the
MANUAL ON button sets the zone to occupied for a set amount of time in the same
manner as the RS Pro or sets the zone to continuously occupied.
INFO button
This button cycles through the same information as the RS Pro and up to 4 additional
inputs defined in the Optional Inputs section of the microblock dialog box in EIKON for
WebCTRL.
MODE button
The MODE button lets you cycle through up to 4 operational modes defined with custom
programming in EIKON for WebCTRL. The sensor displays various information for each
mode based on the setup in the Mode section of the microblock dialog box.
FAN button
Press the FAN button to select the controlled equipment's fan speed. A fan icon on the
left side of the display indicates when the fan is on.

To mount an RS sensor
1
Pull the backplate off the RS sensor. You may need to turn the setscrew in the bottom
of the sensor clockwise until you can remove the backplate.
2
Pull the Rnet communication cable through the wire guide in the backplate.
3
Use 2 screws to mount the backplate to the wall or outlet box.
4
Wire the RS sensor to a control module or another RS sensor. See Wiring an RS
sensor (page 9).
5
Attach the sensor's cover and circuit board to the mounted backplate, inserting the
top first.
