2. Plug one end of the 6-foot interface cable into the
VMA18 socket labeled TSTAT.
3. Plug the other end of the 6-foot interface cable into
the 8-pin female socket of the single-socket adapter.
4. Plug the male end of the single-socket adapter directly
into the BTCVT.
5. Complete commissioning of the VMA18 controller and
disconnect the BTCVT.
Note:
Sensor point information such as temperature,
setpoint, and occupancy is not available during
commissioning.
6. Install the WRZ Series Wireless Sensor and a
WRZ7860-0 Series One-to-One Receiver in the same
