Connect the equipment R to both Rz and either Rh or Rc. A jumper
will be needed. Rc and Rh are internally connected but may be
separated by breaking a twist-off (see step 4 below).

Step 3—Wire Dampers

Each damper has three connections: Close, Open, and Common.
Find the connection points along the lower left side of the 3-Zone
Control. Suggested colors are Close = red; Open = green; Common
= white. Field label and make the connections at the dampers and
at the 3-Zone Control. Be careful not to cross zone numbers.

Step 4—Wire Remainder

Connect the LAT sensor to the LAT and LATC terminals. Polarity
does not matter. If used, connect the HPT sensor to the HPT and
HPTC terminals. If the HPT sensor is not used, you must leave the
10K ohm resistor connected in its place.

If the cooling and heating systems have separate transformers,
twist off the Rc/Rh jumper using a pair of long nosed pliers. Then
connect the R of the cooling transformer to Rc, the R of the heating
transformer to Rh and the common of both transformers to C.
Connect a jumper wire between Rz and Rc. Rc powers G, Y, and
O outputs. Rh powers W outputs.
