ZONEBB3Z(AC/HP)01: Quick Reference Guide
NOTE: ZONEBB3ZAC01 model does
not have HPT connector.
Fig. 6 – Leaving Air Temperature (LAT) Sensor
Please refer to Limit Temperature Levels and Actions Table in the
Installation and Start-Up Instructions for additional information on the
response of the system to LAT/HPT sensors.
Step 6 – Connect the Power Supply
Optional: Use a dedicated 24 VAC, 40 VA, 60 Hz isolated transformer
(not included).
Otherwise, 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 power W outputs.
