Multi-Fan Installation (Daisy Chaining) For Essence® Fans; Power Supply Cable - BIG ASS FANS SmartSense Guia De Instalacion

Multi-fan installation (daisy chaining) for Essence
Up to four Essence fans can be controlled by a 4–20 mA analog signal when connected as shown below. The provided 500 Ω resistor
is required. A 4 mA signal will develop 1 V (minimum speed) across the fan's analog input, and a 20 mA signal will develop 10 V
(maximum speed) across the fan's analog input.
The Essence wall controller is not used when SmartSense is installed. Start/Stop for the fan can be accomplished by using a switch
inline with the AC power to the fan.
