APPLICATION
The AWECv 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-1v, AWEC-3v or a 5 way version AWEC-5v. 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 AWECv version comes with an optional use 10vDC power supply that can be used to power the onboard manual speed potentiometer saving the need to bring a 3rd wire (the 10v source) from the EC fan which reduces the typical connection from 3 wires to 2. The potentiometer shaft/knob can be removed exposing only a hexagonal hole to decrease the ability of tampering post commissioning manual fan speed settings if desired.
