HWS Series
LCD Wall Mount with Analog Setpoints,
Humidistat Control
Product Overview
The HWS analog series measures humidity of the air inside a room. Devices are designed for use in hospital rooms,
laboratories, and other spaces that require precise environmental control. The keypad allows control of setpoint
values. The slide switch position determines the output type (amp or volt). To maintain accuracy, keep vents clear
of dust, debris, etc. The HWS is warranted for period of ve years.

* The HS sensing element has a 1-year warranty. The element is not a part of the 5-year product warranty.
** Accuracy is specified with 24 VDC supplied power with rising humidity.
*** Reset Rate is the time required to recover to 50% RH after exposure to 90% RH for 24 hours.
One side of the transformer secondary is connected to the signal common, so an isolation transformer or
dedicated power supply may be required.
RTD/Thermistors in wall packages are not compensated for internal heating of the product.
EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper
surge protection (EN 61000-6-1:2007 specification requirements).

Installation
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Locate the tab at the top of the sensor housing. Using only the minimum required force, press this tab down and pull the cover
outward from the top. Set the cover aside.

Tab
2. Remove the backplate by unfastening the sensor from the bottom of the backplate and pivoting the sensor outward.
3. Punch out wire opening in the backplate.
4. Position the backplate vertically on the wall, 4 ½ feet (1.4 m) above the oor. Locate away from windows, vents, and other
sources of draft.
