Honeywell HZ322 TrueZONE - DATS, Equipment, and Wireless Wiring; Transformer Wiring

Installation Guide
69-2199—05 4
The DS/BK terminal is used with a variable-speed fan. If
the HVAC equipment has a DS, BK, ODD, or DHUM ter-
minal, wire that terminal to the HZ322 DS/BK terminal.
When 2 or 3 zones are calling for cooling this terminal
will be energized which will run the blower fan at the
normal speed. When only 1 zone is calling for cooling
the fan runs at a reduced speed which will require less
air to be by-passed. Refer to HVAC equipment manufac-
turer instructions.
For oil heat with a separate transformer for cooling,
remove this jumper. For other systems leave jumper
in place and wire to HVAC R terminal with 18 gauge
solid wire.
Connect DATS as shown.
For the placement of DATS in supply duct and
troubleshooting assistance with the DATS, see the Discharge
Air Temperature Installation Instructions Form Number
69 1521.
