2 = 2%
2% models only)
3 = 3%
X = None (2%, 3%,
5 = 5%
and 5% models
only)
INSTALLATION
For all unit types, ensure that the four HS pin holes are
inserted fully onto the unit pin connec tors.
Humidity Outdoor and Duct Units
1. Disconnect power to the unit.
2. Remove probe f rom junction box by loosening black
swage nut and sliding out.
3. Unscrew lter on tip of probe. Set lter aside.
4. Remove HS element by gently pulling from pin
connector. Do not attempt to remove temperature
sensor adjacent to HS element (if equipped).
5. Place new HS element onto pin connec tor. Orient as
shown, or unit will not function (lter will not screw
on if HS is inser ted incorrectly).
6. Replace lter. Re-insert probe into junction box and
tighten swage nut.
* 1% HS sensors used in outdoor
applicatio ns are limited by the
device to 2% accuracy.
The microprocessor-proled
capacitive HS element can be
replaced in the el d without
calibration.
HS sensor elements are sold as open devices.
Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.
