Product Description
HEW3VSTH Schneider Veris Wall Temperature Humidity Sensor
Product Overview
The HEW3VSTH is a wall-mounted temperature and relative humidity sensor from Veris, operating within the Schneider Electric portfolio. This versatile device addresses the common requirement for combined temperature and humidity monitoring in commercial projects through a single, discreet wall plate.
Humidity measurement utilizes a thin-film capacitive element with ±3% RH accuracy, while temperature sensing employs a 10 kOhm type 3 thermistor—the standard curve expected by most North American and international controllers. Outputs are selectable 0-5V or 0-10V voltage signals, compatible with controller inputs, and the unit operates on 24V AC/DC power.

System Integration
Proper placement is critical for accurate measurements. Avoid mounting locations with direct sunlight, supply grilles, door drafts, or heat from office equipment, as these can distort readings while leaving wiring intact.
- Configure output scaling to match controller input range before wiring
- Use the same 24V transformer serving the controller to avoid circulating currents
- Trend humidity data rather than alarming initially, as RH fluctuates rapidly with environmental changes
Application Scenarios
- Office Buildings: Comfort control and condensation risk monitoring for chilled ceiling/beam systems
- Data Centers: Humidity monitoring to prevent static discharge and condensation on cold surfaces
- Laboratories & Clean Rooms: Environmental monitoring for compliance records
- Museums & Archives: Continuous humidity data to protect valuable collections
- Hotels & Residential: Return air condition monitoring in ducted systems
- Healthcare Facilities: Patient comfort and infection control in wards and waiting areas
