LOCATION:
Avoid mounting on outside walls or in direct sunlight.
JUNCTION BOX (J-Box), (Fig. 3)
1. Pull the wire through the wall and out of the junction box, leaving about
six inches free.
2. Pull the wire through the hole in the base plate.
3. Stuff insulation into box behind the sensor plate and screw the plate
firmly to the J-box.
4. Secure the back plate to the box using the #6-32 x 5/8 inch mounting
screws provided.
5. Terminate the unit according to the guidelines in the Termination section.
6. Attach cover by latching it to the top of the base, rotating the cover down
and snapping it into place.
7. Secure the cover by backing out the lock-down screws using a 1/16”
Allen wrench until it is flush with the bottom of the cover.
DRYWALL MOUNTING (Similar to Fig. 3 but without the J-Box)
1. Place the base plate against the wall where you want to mount the
sensor and mark the two mounting holes and the area where the wires
will come through the wall.
2. Drill two 3/16” holes in the center of each marked mounting hole. Insert a
drywall anchor into each hole.
3. Drill one 1/2” hole in the middle of the marked wiring through hole area.
4. Pull the wire through the wall and out the 1/2” hole, leaving about six inches free.
5. Pull the wire through the hole in the base plate.
6. Stuff insulation into the wall behind the sensor plate and screw the plate firmly to the wall anchors.
7. Secure the base to the drywall anchors using the #6 x 1” mounting screws provided.
8. Terminate the unit according to the guidelines in the Termination section.
9. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place.
10. Secure the cover by backing out the lock-down screws using a 1/16” Allen wrench until it is flush with the sides of the
cover.
Note: In any wall-mount application, the wall temperature and the temperature of the air within the wall cavity can cause
erroneous readings. The mixing of room air and air from within the wall cavity can lead to condensation, erroneous
readings and sensor failure. To prevent these conditions, BAPI recommends sealing the conduit leading to the
junction box with fiberglass insulation.
The Delta Style room humidity transmitter
measures relative humidity (RH) and outputs a
0 to 100% RH on either a 4 to 20mA, 0 to 5V or
0 to 10V signal. It can be ordered with optional
temperature sensor and LCD display. The unit is
powered by a wide selection of AC or DC power
depending on the signal selection. The optional
LCD display can selectively show RH and/or
temperature values. The optional temperature
sensor can use any 2-wire passive sensor.
