Product Summary:
The Subzero Mega Chill -2 is a rugged, standalone chiller controller designed for two-compressor refrigeration systems. It offers an intuitive LCD and LED display, password-protected parameter settings, and multiple safety trips to ensure reliable, uninterrupted operation.
Key Features:
Dual-compressor on-off control with time-delay sequencing
7-segment LED + backlit LCD display for status, setpoints, and alarms
Audible buzzer and LCD messages for all fault conditions
HP, LP, OL, OSS trips for compressor; overload protection for pump & condenser
Regulates system water level via solenoid valve
6 NTC analog inputs (CONTROL, E/INLET, E/OUTLET, C/INLET, C/OUTLET, AFT)
Multiple digital inputs (HP, LP, OSS, Comp O/L, Pump O/L, etc.)
Relay outputs: Compressor, Pump, Condenser Fan, Alarm, Solenoid Valve, Bitzer Reset
Applications:
Industrial process chillers
HVAC package units
Water-cooled refrigeration systems
Food & beverage cold storage
Product Benefits:
Ensures optimal compressor staging for energy efficiency
Robust fault protection minimizes downtime and repair costs
User-friendly interface simplifies setup and monitoring
Password-protected “PROKEY” prevents unauthorized access
Universal 230 VAC (110 VAC optional) for global compatibility

FAQ:
Q: Can it control more than two compressors?
A: The Mega Chill -2 is optimized for two-compressor systems. For up to four compressors, see Subzero Ultra Chill series.
Q: How is the parameter lock implemented?
A: A hardware “PROKEY” dongle locks programming levels; without it, parameters are read-only.
Q: What temperature range does it support?
A: –30 °C to +50 °C with 0.5 °C resolution; sensor inputs accept NTC probes.
