NOT be connected to any terminal at the user interface. Connecting the shield to
ground at both ends can cause current loops in the shield, reducing shield
effectiveness.
Connect one pair of the two--pair (minimum) cable to the A and B communication
terminals, and another pair to the C and D terminals at both ends of the cable. The
shield wire should ONLY be connected at the indoor equipment ground or C
terminal. Note that some outdoor units only require the A and B connections. See
the outdoor unit installation instructions for more information.
4.4.2. Damper Control Module (zoning systems only)
All zoning wiring is run back to the Damper Control Module. Select a location near
the furnace or fan coil where wiring from the control, each Remote Room Sensor or
Smart Sensor, each damper actuator, and the equipment itself can come together
easily. The Damper Control Module is approved for indoor use only and should
never be installed with any of its components exposed to the elements. The Damper
Control Module (and zone dampers) may be installed in any area where the
temperature remains between --4

important consideration.
