Veris Industries HW2LA2A Sensor

The Veris Industries HW2LA2A is a commercial-grade wall mount humidity sensor designed for high-precision environmental monitoring in building automation systems. As the direct replacement for HWL2XSTA, this HW2 Series sensor integrates a thin-film capacitive sensor element that provides reliable 2% RH accuracy. This unit is engineered with a multi-sensor platform, featuring a segmented LCD with a three-button interface and a temperature transmitter to deliver dual-parameter climate data via analog 4 to 20mA, 0 to 5V, or 0 to 10V outputs.

For field technicians, the Veris HW2LA2A offers a significant advantage through its replaceable RH element, which allows for NIST traceable recalibration or repair without removing the baseplate. The polarity insensitive 2-wire or 3-wire wiring configuration simplifies installation on standard 18-24 AWG circuits, ensuring BAS controller compatibility across various legacy and modern HVAC platforms. With its IP20 rated high-impact ABS housing, this sensor is optimized for indoor air quality monitoring and ASHRAE compliance in schools, office buildings, and hospitals.

• Field-Replaceable Elements: Maintain 2% humidity accuracy and minimize system downtime by swapping the NIST calibrated sensor module on-site.
• Flexible Analog Outputs: User-selectable 4 to 20mA, 0 to 5Vdc, or 0 to 10Vdc signaling ensures seamless integration with most HVAC/R controllers.
• Dual-Parameter Sensing: Consolidate your installation by monitoring both relative humidity and ambient temperature from a single wall-mounted device.
• Robust Design: Durable high-impact ABS plastic enclosure with a segmented LCD provides clear local diagnostics for balance and commissioning.

Is the HW2LA2A compatible with older HWL2XSTA installations?
Yes, the Veris HW2LA2A is the direct replacement for HWL2XSTA. It fits the same application footprints and utilizes similar analog output logic, making it a drop-in upgrade for existing HVAC control systems.

Can I change the temperature setpoint from the LCD screen?
The 3-button segmented LCD allows for setpoint adjustments of temperature, RH, or fan speed (selectable via internal DIP switches) providing local control for commercial environmental monitoring.

What wiring is required for this sensor?
The unit supports 18 to 24 AWG wire. It functions in 2-wire mode (loop powered 12-30VDC) for 4-20mA or 3-wire mode for 0-5V/0-10V configurations.
