SV Supply Control TRUFLOW Operation with SV Control for the following applications: • SAT direct gas fired supply units • Other direct gas fired supply units with unit mounted variable speed drive VSD • Supply units with electric heating, hot water heating, or no heating or cooling The Touchscreen receives a signal from the duct mounted J-couple that controls the exhaust motor VSD. The exhaust motor variable speed drive slows or speeds up the exhaust fan motor to maintain the required exhaust volume to match the amount of cooking. Simultaneously the Truflow controls the Spring Air SAT supply fan motor or other supply fan motors supplied by others. The supply variable speed drive changes the frequency of the supply fan motor to modulate the supply air into the kitchen space in proportion to the exhaust air volume.
