Key Features & Benefits
Soft Starting & Variable Speed Control
Supports timed Y/Delta soft starting for fixed-speed applications and full Variable Speed Drive (VSD) compatibility. This reduces startup current by up to 7× peak starting amps while enabling on-demand motor speed and pump RPM control. With up to 85% turndown, the system can reduce electrical power consumption by up to 30%.
Adjustable Pressure Control
Simple and precise PSI cut-in and cut-out adjustments allow operators to maintain optimal system pressure based on real-time air demand, improving efficiency and performance.
Integrated Time Clock
A built-in programmable daily on/off scheduling function ensures the compressor operates only when required, eliminating unnecessary run time and reducing energy costs.
Lead/Lag Control
Automatically manages and balances run hours across multiple compressors, extending equipment life and improving overall system efficiency.
Advanced Unit Protection
Includes configurable high- and low-voltage protection, high-pressure safety limits, and high-temperature / low-oil shutdown safeguards to prevent equipment damage and unplanned downtime.
Maintenance Reminders
Automated service alerts notify operators when maintenance is required, including:
- Oil filter replacement
- Air filter replacement
- Air/oil separator filter replacement
- Compressor oil changes
- Motor bearing lubrication
- Full unit inspection service
Fault History Logging
Stores date- and time-stamped fault records, enabling faster troubleshooting and minimizing downtime.
Remote Alarm Dry Contact Output
Provides a dry contact output for connection to a remote alarm or building management system (BMS), ensuring immediate notification of compressor faults or shutdowns.
Remote Start/Stop Function
Supports connection to a remote NO/NC on/off or start/stop switch, allowing safe and convenient operation from elevated or hard-to-access locations.
Multi-Language Support
Available in English, Spanish, and additional languages for global usability.
Hour Meter Tracking
Displays total run hours, as well as loaded and unloaded run hours, enabling accurate maintenance planning and performance monitoring.
