VCCX2 Controller Technical Guide
E-BUS Return Air Temperature &
Humidity Sensor
The ASM01840 E-BUS Return Air Temperature & Humidity
Sensor connects to the VCCX2 Controller. A 50-foot EBC E-BUS
cable (provided) plugs into the sensor’s attached three-foot cable
and then plugs into the E-BUS port of the VCCX2 Controller or
other E-BUS Expansion Board. The sensor should be mounted in
the upright position as shown in an area that is protected from the
elements and direct sunlight. See Figure 18, this page for details.
NOTE: If using multiple E-BUS Sensors or Modules, the
E-BUS Hub (ASM01635 or G033970) or E-BUS
Adapter Board (ASM01878) may be required.
