Neptronic Humidity Controls
For precise, reliable, and energy-efficient
HVAC performance
How do humidity controls work with Neptronic humidifiers?
Neptronic Humidity Controls deliver precise and reliable humidity management for commercial and institutional HVAC applications. Designed for dedicated humidification and dehumidification control, these controls ensure stable indoor environmental conditions while supporting energy-efficient system operation.
Engineered for stand-alone operation or BACnet® network integration (model dependent), these controls features configurable inputs and outputs, advanced PID control algorithms, and compatibility with external sensors. The intuitive interface simplifies commissioning and allows for flexible adaptation across a range of room and duct applications.
Operating on 24 Vac power, Neptronic Humidity Controls provide dependable performance when paired with Neptronic humidifiers or integrated into broader building automation systems, offering long-term reliability and simplified installation.
Why use Neptronic humidity controls for indoor environments?

HRO Compatible with duct, wall, and external temperature sensors for tailored installation.
Available Models
HRO
- Integrated RH Controller: Wall-mounted humidistat with PID control for humidification and dehumidification.
- Flexible I/O: Supports analog outputs, relay contacts, and optional BACnet (HROB) for BMS integration.
SH Series
- High-Limit Humidistats: Wall- or duct-mounted devices that monitor RH and shut down humidifiers when humidity exceeds the set limit.
- Built-In Sensors & Outputs: Integrated humidity sensing with adjustable setpoints (typically 20–90 % RH) and relay or 0–10 V outputs for HVAC control systems.
SHS & HR Series
- Humidity Monitoring Devices: Room and duct humidistats/sensors used for high-limit protection and RH monitoring in HVAC humidification systems.
- Reliable RH Feedback: Adjustable setpoints or sensor outputs designed to integrate with humidifiers and building control systems.
Frequently Asked Questions
What are Neptronic humidity controls?
Neptronic humidity controls are HVAC control devices used to measure, regulate, and maintain relative humidity in commercial, institutional, and industrial buildings.
How do Neptronic humidity controls work?
Neptronic humidity controls compare the measured humidity level to the setpoint, then send a control signal to the humidifier, dehumidification equipment, or building automation system.
Can Neptronic humidity controls support both humidification and dehumidification?
Yes. Neptronic humidity controls can support humidification and dehumidification sequences from a single controller, depending on the selected model and application.
Can Neptronic humidity controls integrate with BACnet systems?
Yes. Select Neptronic humidity control models are available with BACnet MS/TP integration, allowing connection to a building automation system for monitoring and control.
What types of sensors can be used with Neptronic humidity controls?
Neptronic humidity controls can work with room, duct, wall-mounted, and external sensors, depending on the model and installation requirements.
Where are humidity controls installed in an HVAC system?
Humidity controls can be installed in rooms, ducts, air-handling units, or control panels, depending on whether the system needs space humidity control, duct monitoring, or high-limit protection.
