The Reliable Controls® MACH-Stat™ is a fully programmable, versatile BACnet® controller designed for space control applications where user access is required without the need of a PC.

The built-in large LCD screen allows operators to access/view/change/override up to 42 different points within a Reliable Controls® MACH-System™. The MACH-Stat™ can be ordered with optional realtime clock for stand alone applications, setpoint slider, humidity sensor, and occupancy sensor.
