G I ENERAL NFORMATION
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 EA200-12, EA400-12,
EA800, and EA800-ip. 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.
T O HEORY OF PERATION
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 EA200-12, EA400-12, EA800, and EA800-ip, 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 pry open top cover until it swings loose from the base (See Figure 1). Remove screwdriver from gently
pry slot, grasp cover beneath detached flange and swing to the right until cover fully detaches.
F 1IGURE
With the cover 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 EnviroAlert® monitoring device using the following wiring scheme (See Figures 2 and 3). Extend
the length of probe wiring up to 1,000’ (304.8m) using 22-18 AWG twisted pair.
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.
F 3IGURE
(Shows typical use with an EnviroAlert® device)
Power Input = 12VDC Positive
GND = 12VDC Negative
Sink = Wire to either the white/brown or the white/red sensor input on the DTA-4 or DPM-4
This output is only used for the DTA-4 or DPM-4.
Source = Wire to negative (-) terminal on sensor input of the desired device:
EA200-12, EA400-12, EA800, EA800-ip UTA-1, TA-2HLD, and TA-3HLD (See Figure 3)
Sensor input positive (+) is not used.
F 2IGURE
To insure proper operation, test weekly.
