General Information
The Winland HA-III+ is a sensor used for monitoring remote locations for rising or falling
rates of humidity. The HA-III+ is designed and approved to be used with the EnviroAlert®
family of monitoring devices including the EA800, EA400-12 and EA200-12. The HA-III+
may also be used with Winland legacy monitoring devices including the TA-2HLD,
TA-3HLD, UTA-1, DTA-4 and DPM-4.
The setup of high and low limits is done through the interface on the monitoring device
you are connecting to.
Important Note: HA-III+ must not be used with monitoring devices that are powered
with 24V AC/DC. When used with Winland legacy monitoring devices such as UTA-1,
TA-2HLD, TA-3HLD, DTA-4 or DPM-4, the monitoring devices must be set to read
Fahrenheit.
Theory of Operation
The HA-III+ senses the ambient room humidity electronically using a capacitive sensing
element. Humidity should be expected to vary from room to room and from one area of
a room to another. Ventilation and airflow will greatly affect relative humidity.
When programming the HA-III+ sensor on the monitoring device, the initial reading you
receive should be considered a base reading. Allow at least 30 minutes of operation
for sensor to stabilize prior to setting your high and low limits. It is necessary for the
temperature of the sensor to stabilize before the readings are considered accurate. The
outputs of Winland’s electronic monitoring devices react within seconds of a limit being
exceeded. A sudden burst of humid air from a door opening or a ventilation system
starting, could cause a brief change in the humidity reading. To avoid false alarms, a time
delay should be programmed into the EA800, EA400-12, EA200-12, UTA-1 or TA-2HLD. It
is strongly recommended to utilize a time delay unless your application requires
instant notification.
Installation
The HA-III+ sensor should be flush mounted directly to a flat surface like a wall. The
sensor should be located in an area free from drafts, heat sources, and direct sunlight. It is
recommended that the sensor is mounted at a height of 4-5’ (1.2-1.5 m) from the floor.
To begin installation of the HA-III+, you must first remove the cover. Do not use excessive
force while removing the cover, you may crack or break the plastic housing. Grasp the
HA-III+ between your thumb and index fingers along the long slotted surfaces of the
sensor with the Winland logo facing you. Using a flat bladed screwdriver, insert tip of
screwdriver into pry slot and gently pry open top cover until it swings loose from the
base (See Figure 1). Remove screwdriver from pry slot, grasp cover beneath detached
flange and swing to the right until cover fully detaches.
With the cover now fully removed, fasten the base of the sensor to the wall via the screw
holes in the base plate using the two screws provided.
Wire the HA-III+ to your monitoring device using the following wiring scheme
(See Figures 2 and 3).
Connection will either be made to the Sink terminal screw or the Source terminal
screw, never both.
Avoid tucking excess wires under the PC board. To allow for maximum air movement,
make certain that no wires surround the sensor which is located in the lower left hand
corner of the PC board. Replace the cover by aligning the slots in the cover with the tabs
on the base and slide the cover back toward the mounting surface until both side flanges
snap into place.
