Temperature Sensor Connections (For RH/Temperature Sensor Combination Units only)
All of the connections to the temperature sensor connections should be made to the (2 or 3) 22 AWG 24” Flying Lead
wires using wire nuts or crimp style connectors. Please note that the wire colors will change depending on the type and
value of the sensing element used.
Duct Mounting Configuration:
The RH transmitter should be placed away from areas of excessive moisture, corrosive fumes, vibration, or extremely high
temperatures. All of the RH sensors have a +/- 3% interchangeability. It is recommended to do a single point calibration
for a much higher accuracy.
1. Drill a ¾” diameter hole in the duct where the sensor is to be mounted.
2. Now insert the stainless steel probe into the hole until the foam is in direct contact with the duct and attach
the RH transmitter by using the (2) #8 x ¾” self tapping TEK screws that are included with the installation
instruction.
3. Remove the cover and install your conduit connectors or watertight fittings. The outer ring should be used
when using a ½” NPT conduit fitting. Please note that the inner ring will knockout first and then the outer
ring should be tapped in (1) or (2) locations with a screwdriver before it can be peeled out. The cover will
be connected to the housing by the RH sensor leads. To remove the RH sensor leads from the housing
see Figure #8.
4. Next connect all of the wires to the corresponding terminal blocks and/or flying leads the wires to the
corresponding terminal blocks as shown in Figure #7 and Figure #9.
5. Now make sure that all of the dipswitches are properly configured as per Figures #2, #3, #5, and #6 before
initially powering the unit.
