INSTALLATION

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

1. Choose a location on the return air duct.

2. Drill a 7/8” diameter hole in the duct for the sensor probe.

3. Mount the junction box housing to the duct using self-tapping screws (included).

4. Insert the probe through the black swage tting into the duct. Tighten the swage tting.

5. Wire the probe (see the Wiring section). Leave wires at factory length to allow for a service loop (to remove the sensor from junction box for service without disturbing the conduit).

TEST POINTS AND SETUP VERIFICATION

0.42

1VDC

Voltmeter shows reading of 42% RH

WHITE (+)

For 4–20 mA versions: Test leads output 0-1 VDC corresponding to 0 to 100% RH sensor reading. For example, a 0.42 VDC output on test points equals 42% RH sensor reading. These test points also provide an output that veries the motherboard accuracy when the HS element is removed. Connect test point leads to voltmeter only. This output is not suitable for connection to a DDC panel.

To check the motherboard functionality using the test leads, remove the sensor element. A 1.0 VDC reading veries motherboard functionality.

To verify sensor accuracy, de-power the unit and insert a replacement HS element. Repower the unit and compare readings to the original sensor. For example, if test points read 0.40 VDC (40% RH) with the original sensor, and 0.45 VDC (45% RH) with the replacement sensor, then the original sensor is 5% o specication. This method of ensuring accuracy oers more precision than using slings or other devices, and it eliminates the need to manually adjust sensors to an unstable standard.

Note: Temperature, body sweat, and breath eect humidity. Ensure that conditions are stable to evaluate performance.

The lter may be washed using warm water and a soft brush. Do not attempt to scrub the HS element.

For 0-5V/0-10V versions, use the output as a test point and scale accordingly.

SENSOR REPLACEMENT

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

1. Disconnect power to the unit.

2. Remove the probe from the junction box by loosening the black swage nut and sliding it out.

3. Unscrew the lter on the tip of the probe. Set lter aside.

4. Remove the HS element by gently pulling from the pin connector. Do not attempt to remove the temperature sensor adjacent to the HS element (if equipped).

5. Place a new HS element onto the pin connector. Orient as shown, or the unit will not function (the lter will not screw on if the HS is inserted incorrectly).
