1. Push tab on bottom of cover and lift cover from back plate. (See Figure 1).
2. Select the mounting location, away from diffusers, lights, or any external
influences.
3. Mount transmitter on a vertical surface to a standard electrical box using the two
#6 M2C type screws provided.
4. Pull wires through sub base hole and make necessary connections.
5. Reattach cover to base plate.
Wiring
Use maximum 18 AWG wire for wiring to terminals. Refer to figures 2 through 5 for
wiring information.
Current Output Models (RHP-XW1X)
Current output models must be powered with 10-35 VDC supply voltage. Wire the
RH current output as shown in Figure 2. If the unit has a 4-20 mA temperature out-
put, wire the temperature receiver between terminal 3 and the negative terminal of
the power supply. If the unit has a passive temperature sensor, wire to terminals 4
and 5. If the RH output is not required, wire the negative terminal of the power sup-
ply to terminal 1 of the transmitter. If the temperature output is not used, it may be
left disconnected.
Voltage Output Models (RHP-XW2X)
Wire as shown in Figure 3. Voltage outputs may be powered with 15-35 VDC or 15-
29 VAC. Note polarity when using DC power. If the unit has a voltage temperature
output, wire the temperature receiver between terminal 4 and negative terminal of
power supply. If the unit has a passive temperature sensor, wire to terminals 5 and
6. For units with RH and temperature voltage outputs, the RH or Temperature out-
put may be used by itself.
Models with Selectable Current or Voltage Outputs (RHP-XW44)
These models may be wired for current or voltage output. Note that both outputs
must be wired either for current or voltage. It is not possible to wire one output for
current, and the other for voltage.
Prior to wiring, verify that the Current/Voltage select switch is set to current or volt-
age as desired. Refer to “Setting the Current/Voltage Select Switch”.
Current Output Selected:
Wire as shown in Figure 4. Current outputs must be
powered with 10-35 VDC. If the RH output is not required, wire the negative termi-
nal of the power supply to terminal 1 of the transmitter. All units come with 4-20 mA
RH and Temperature outputs. If the 4-20 mA temperature output is not used it
maybe left disconnected. If the unit has a passive temperature sensor, wire to ter-
minals 7 and 8.
Voltage Output Selected:
Voltage outputs may be powered with 15-35 VDC or 15-
29 VAC. Note polarity when using DC power. Wire the RH voltage output as shown
in Figure 5. If the unit has a voltage temperature output, wire the temperature
receiver between terminal 6 and the negative terminal of the power supply. All units
come with RH and Temperature voltage outputs. If the temperature or RH voltage
output is not used it may be left disconnected. If the unit has a passive temperature
sensor, wire to terminals 7 and 8.
Setting the Current/Voltage Select Switch
Remove the cover of the unit as shown in Figure 1. The Current/Voltage select
switch is located on the back of the circuit board. Set the switch “IOUT” for current,
“VOUT” for voltage.
