UC7 Controller Current Range
The temperzone UC7 Unit Controller provides system protection functions such as coil frost protection, de-icing, high head pressure and low suction pressure cut-out. It also protects against rapid cycling of the compressor(s) and loss of refrigerant. Various methods of head pressure control (or limiting) are employed in temperzone units. The particular method used varies from model to model, but is also handled by the Unit Controller. In combination, these features deliver optimised performance across a wide operating temperature range.

UC7 Controllers have been progressively introduced into temperzone air cooled and water sourced models from 2013, replacing the previous OUC4 Controllers.
These are not an accessory. They are an integral part of each air conditiong system.
