Schneider Electric (Barber Colman) HC-201 Room Humidistat

The Schneider Electric HC-201 represents a reliable standard for on-off humidity control in commercial and industrial HVAC systems. Designed and manufactured under the Barber Colman brand legacy, this room humidistat provides precise two-position control for humidifiers, dehumidifiers, and air handling units. Its wide 10 to 90% RH setpoint range allows for versatile deployment across varied environments, from critical data centers to general office ventilation. The unit features a fixed 5% RH differential, ensuring system stability by preventing short-cycling of equipment. Built with a robust NEMA 1 enclosure, the beige plastic housing and brushed bronze insert provide a professional aesthetic for wall-mount installations. As an electromechanical humidity sensor, the HC-201 is preferred by contractors for its simplified humidistat wiring and long-term durability in low voltage control circuits, making it a staple for maintaining optimal indoor air quality and equipment protection.

Key Benefits:

• Broad Control Range: Manages humidity levels from 10% to 90% RH for maximum application flexibility.
• Proven Reliability: Durable electromechanical design reduces electronic failure points in HVAC control systems.
• Stable Operation: Fixed 5% differential maintains consistent relative humidity without excessive equipment wear.
• Standard Installation: Designed for easy mounting on horizontal or vertical electrical boxes.
• Professional Design: NEMA 1 rated enclosure with a classic aesthetic suitable for commercial interiors.

Common Questions:

What is the electrical rating for the HC-201?
The unit is designed for low voltage or line voltage control, typically rated up to 120/240 VAC for standard SPDT switching applications in commercial HVAC units.

Can the setpoint be calibrated in the field?
While the HC-201 is factory-calibrated, technicians can adjust the dial settings to align with a calibrated hygrometer if local environmental conditions require fine-tuning.

Does this unit support humidification and dehumidification?
Yes, the two-position SPDT switch allows you to wire the unit to either make or break the circuit on a rise or fall in humidity, supporting both sequences.
