Unit Mounted Controller (UMC): 

Designed to enhance the unit
operation with more flexibility, accurate control and operating models. The
unit mounted controller provides an increased level of comfort in the
conditioned space together with solid-state reliability and ease of operation.
When UMC is used, Freeze Protection is set from the factory at 40degF. Some
functionality of our proven UPM module are incorporated into the unit mounted

controller/thermostat designation.
