APPLICATION
The AWEC modules are intended for use as a low cost alternative to traditional plug in relays & potentiometers for Auto/Off/Manual EC fan speed interlocks & control. The device is available in 3 versions – a Single output module AWEC-1, AWEC-3 or a 5 way version AWEC-5. The output signal to the EC fan is derived either from the onboard potentiometer/s (in manual mode) or to pass out the 0-10vdc signal/s from an external control device ie BMS EC fan speed control outputs. The potentiometer shaft / knob can be removed exposing only a hexagonal hole to decrease the ability to tamper post-commissioning manual fan speed settings if desired.
