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 AWECv-1,
AWECv-3 or a 5 way version AWECv-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 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.
