Technical Instructions
Introduction
The RS Standard and RS Pro are thermistor-
based temperature sensors. The sensors are
designed to be used with the ZN-Line, SE-
Line and ME-Line controllers. An Rnet sensor
network can have up to four RS Standards
and one RS Pro.

RS Standard
The default address of an RS Standard is set
to 1. To change the address, unscrew the two
circuit board screws behind the cover plate,
then take off the cover plate. Set the address
jumper to 2, 3, or 4, then screw the circuit
board back onto the cover.
RS Pro
The RS Pro features provide the occupant
with setpoint and override control within the
limits established by the building
management or the system operator. The RS
Pro needs no addressing because only one
resides on each Rnet.
The RS Pro has:
• a digital display for occupancy, zone
temperature, and alarm bell icon
• a Manual On button
• Warmer and Cooler buttons
• an Info button to cycle through displays
Digital Display
The digital display shows Celsius values to
the nearest 0.5 degree. The digital display
shows Farenheit values to the nearest full
degree.
Occupied displays when the zone is
occupied, whether from a regular schedule or
a manual override.
Manual On
The override time displays if you press the
Manual On button. Press the button again if
you want to increase the occupied time. You
can cancel by pressing the button until 0
displays. After pressing the Manual On
button, wait five seconds for the display to
show the current zone temperature again.
Setpoint Adjustment
The Warmer and Cooler buttons give the
occupant limited ability to change the zone’s
setpoint. When Warmer or Cooler is pressed,
the average of the current heating and
cooling setpoints displays. If Warmer or
Cooler is pressed again, both setpoints are
lowered or raised by an amount determined
on the RS microblock’s Properties page,
displaying a new average setpoint.
For example, if the cooling setpoint is 76, the
heating setpoint is 70, the current average
setpoint is 73 and the setpoint adjustment is

set to 2, pressing Warmer twice raises both
setpoints and the average, resulting in a
cooling setpoint of 78, a heating setpoint of
72, and an average setpoint of 75.
Info
The info button cycles through:
• the zone temperature
• the outside air temperature, if enabled
• the override time in minutes
• the heating setpoint
• the cooling setpoint
Rnet Wiring
The Rnet communicates at a rate of 115 kbps,
and uses a daisy-chain, star, or hybrid
configuration.

Wiring Recommendations
Use the specified type of sensor cable for
maximum signal integrity.
If bare communication wire comes in contact
with the cable’s foil shield, drain/shield wire,
or a metal surface other than the connector,
the sensor may not communicate. When
connecting the wire, keep the following
guidelines in mind:
• Partially cut, then bend and pull off the
wire’s outer jacket so that you do not
nick the inner insulation. See Figure 2.

• Strip about 1/4 inch (6 mm) of the inner
insulation from each wire. When you
insert the wire into the connector, do
not allow more than 1/8 inch (3 mm)
bare communication wire to protrude.
See Figure 3.
• Twist together the drain or shield wires
from both pairs, then insert them into
the connector with the black ground
wire.

Mounting
After wiring, connect the terminal block,
wires facing up, to the back of the sensor’s
circuit board. See Figure 4. Replace the
sensor’s cover. Turn the setscrew one full turn

removed.
Rnet Port
The Rnet port on the RS Standard and RS Pro
allows a laptop computer to be connected to
the system so that test and balance
procedures can be conducted. Refer to the
APT Technical Instructions for information on
using an APT. Refer to Connecting to RS
sensors using an APT in WebCTRL Help to
learn how to access a WebCTRL system
through the Rnet port.
Connect the Rnet Access Cable to the sensor
by first holding the cable end horizontally,
prongs facing upwards, under the Rnet port.
After the prongs are hinged into the front of
the Rnet port, push the back of the cable end
up into the Rnet port so that the cable is
vertical. Click into place.
NOTE You must connect the Rnet Access
Cable to an APT and its cables, then to the
laptop.
