Figure 2. Connect Controller to Multiple Indoor Units Wiring Connections
Connecting to Multiple Indoor Units
Connect the controller to multiple indoor units, up to 16. Use 4-conductor shielded cable to connect
to the first indoor unit, then daisy chain control wiring to each indoor unit using the XYE terminals
in the electrical control box of the indoor unit. Do not daisy chain 12V power cable. See Figure 2.
NOTE
–
All of the indoor units connected to the controller must be on the same refrigerant circuit,
connected to the same outdoor unit.
NOTES -
1. Connect “R/12V” on the controller to terminal “12V” on the first indoor unit only. 12V
connection provides power to controller; connection to multiple indoor units will
damage controller and indoor unit boards.
2. Connect terminal “C/GND” on the controller to terminal “E” on the indoor unit.
3. Ground cable shielding at one end of each length of cable, except at controller.
4. Use stranded, shielded, 18 GA cable.
