MACH-ProZone
BACnet® Controller

Small, durable and packed with flexibility, the Reliable Controls MACH-ProZone is a fully programmable BACnet Building Controller (B-BC) with highly scalable I/O in a very small footprint. The MACH-ProZone is ideal for a wide range of applications that include small to mid-sized roof top and heatpump applications, and small mechanical room applications.

Typical Maximum Object Configuration

There are physical limitations to the number of inputs, outputs, and SMART-Sensors that can be connected to a MACH-ProZone controller. For other object types, there are no imposed limits for the maximum number of objects of a single type that can be created. The total number of objects (including inputs, outputs, and SMART-Sensors) is limited to 128, and is also limited by the onboard memory. The table below details typical databases that fit in all models.

64 8 4 2 4 4 10 128 4 8 8


* Tables and Runtime Logs are not counted in the 128 object limit. Inputs, outputs, and the device object are counted in the 128 object limit.
** Trends are configured to store 128 samples.
*** All models accommodate a maximum of 8 SMART-Sensors.
