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.

Certification

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. 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 the Base and Expanded memory models.

Memory* Variables Loops Schedules Calendars Tables** Groups Multipoint Trend Runtime** Arrays Program SMART-Sensor
Base 48 4 2 1 2 2 2 32 2 8 4
Expanded 64 8 4 2 4 4 10 128 4 8 8

* MPZ-44, 48, and 84 ship with base memory – MPZ-88 and -XM models ship with expanded memory
** 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.
*** All models accommodate a maximum of 8 SMART-Sensors
