BC means Department Circuit. BC or BC controller is referring to the controller Employed in the piping branch unit in a very VRF system. It controls the level of refrigerant flowing to each circuit based upon the cooling demand.

TC means Thermocouple. TC is a form of temperature sensor consisting of two wires of different metals joined at Every stop. It can be Commonly Utilized in fuel furnaces and incredibly hot water tanks for valve and Procedure controls.

Typically, the duct measurement can be found proper immediately after SAD to indicate the supply air duct sizing. It's also typical to hold the Unhappy phrase bodily painted on the availability duct.
