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.
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.
Connect DATS as shown.

When a wireless thermostat, Portable Comfort Control, wire-
less outdoor air temperature sensor, or other RedLINK™ wireless
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.
