device is used on systems up to four zones, wire the THM4000
Wireless Adapter Module to the ABCD terminals on the zone panel.
For systems with more than 4 zones, see page 11.
CAUTION: Do not wire the A-B-C-D terminals of the THM5320R Wireless Equipment Interface Module
to the A-B-C-D terminals on the HZ322 zone control panel. Doing so will damage the components.

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 copper wire.
The DS/BK terminal is used with a variable-speed fan.
If the HVAC equipment has DS, BK, ODD, or DHUM ter-
minals, wire that terminal to the DS/BK terminal. When
greater than 25% of zones are calling for cooling, this
terminal will be energized and the fan will operate at nor-
mal speed. When 1 zone or fewer than 25% of zones are
calling for cooling, the terminal will be de-energized and
the fan will run at a reduced rate, which will reduce the
amount of air that needs to be bypassed. This reduces
blower speed on most variable speed blowers. Refer to
HVAC equipment manufacturer instructions.
