The Series RHPLC Wall Mount Humidity/Temperature Transmitter is a compact
economical sensor for the building automation marketspace. The stylish housing is
well vented to provide air flow across the sensor to improve measurement accuracy.
Each unit utilizes a capacitive polymer sensing element to deliver a proportional
analog output. A combination humidity and temperature model can be configured
with current, voltage, RTD, or thermistor output. A wide selection of passive RTD or
thermistor temperature sensors are available in this series.
FEATURES/BENEFITS
• 2% or 3% accuracy models
• Humidity only or temperature and humidity combo
• Wide selection of passive thermistor or RTD temperature sensors
APPLICATIONS
• Air economizers
• Room comfort monitoring

INSTALLATION
WARNING
Disconnect power supply before installation to prevent electrical
shock and equipment damage
Make sure all connections are in accordance with the job wiring diagram and in
accordance with national and local electrical codes. Use copper conductors only.
CAUTION
Use electrostatic discharge precautions (e.g., use of wrist straps)
during installation and wiring to prevent equipment damage.
CAUTION
Avoid locations where severe shock or vibration, excessive
moisture, or corrosive fumes are present.
Wiring
Use a minimum of 22 AWG to maximum 18 AWG wire for wiring to terminals. Refer to
Figures 2 and 3 for wiring information.
Current Output Models: Wire as shown in Figure 2. Current outputs must be powered
with 10-35 VDC. If the RH output is not required, wire the negative terminal of the
power supply to terminal 1 of the transmitter. If the unit has a passive temperature
sensor, wire to terminals 3 and 4.

designed for AC voltage operation.
CAUTION
MOUNTING
1. Push tab on top and 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

4. M2C type screws provided.
5. Pull wires through sub base hole and make necessary connections.
6. Reattach cover to base plate

Voltage Output Models: Voltage outputs may be powered with 10-35 VDC (0-5 V
models), 15-35 VDC (0-10 V models) or 10-29 VAC (0-5 V modes), 15-29 VAC (0-10
V models). Note polarity when using DC power. Wire the RH voltage output as shown
in Figure 3. If the unit has a voltage temperature output, wire the temperature receiver
between terminal 4 and the negative terminal of the power supply. 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 4 and 5.

TROUBLESHOOTING
1. Verify that the unit is mounted in the correct position.
2. 4 to 20 mA Models:
Verify appropriate supply voltage. The transmitter requires a minimum of 10 and a
maximum of 35 VDC at its connections for proper operation. Choose a power supply
with a voltage and current rating which meets this requirement under all operating
conditions. If the power supply is unregulated, make sure voltage remains within these
limits under all power line conditions. Ripple on the supply should not exceed 100mV.
Loop Resistance – The maximum allowable loop resistance depends on the power
supply voltage. Maximum loop voltage drop must not reduce the transmitter voltage
below the 10 VDC minimum. Maximum loop resistance can be calculated with the
following equation. Vps is the power supply voltage.
Rmax =
Vps-10.0
20 mA
Some receivers, particularly loop powered indicators, may maintain a fixed loop
voltage to power the device. This voltage drop must also be subtracted from the power
supply voltage when calculating the voltage margin for the transmitter. The following
equation takes this into account. Vrec is the receiver fixed voltage.
Rmax =
Vps-10.0-Vrec
20 mA
Voltage Output Models:
Verify appropriate supply voltage. The voltage output models require a 10-35 VDC (0-5
V models), 15-35 VDC (0-10 V models) or 10-29 VAC (0-5 V modes), 15-29 VAC (0-10
V models) for proper operation maximum. Maximum output load is 5 mA.
MAINTENANCE/REPAIR
Upon final installation of the Series RHPLC, no routine maintenance is required. The
Series CDWP is not field serviceable and is not possible to repair the unit. Field repair
should not be attempted and may void warranty.
