Installation
!
WARNING
Be sure that power supply has been
turned o before beginning installation.
Do not operate controller with wet hands.
!
CAUTION
Do not install controller in areas where
harmful gases containing sulfur or
other damaging agents may exist or the
controller may be damaged.
Clean controller using a clean, damp
cloth. Do not spray cleanser on or around
controller.
IMPORTANT
Electrostatic discharge can aect electronic
components. Take precautions to neutralize
electrostatic charge by touching your hand
and tools to metal prior to handling the control.
IMPORTANT
Read all of the information in this manual
before using this controller. All wiring must
conform to local and national building and
electrical codes and ordinances. This is a
12 VDC controller. Do not install on voltages
higher than 12 VDC.
• This manual provides the installation
instructions for this controller. Refer to the
included wiring diagrams to connect the
controller to the indoor unit.
• The controller uses low voltage. Keep a
minimum distance of 12” (305 mm) between
low voltage control wire and high voltage
power wires.
Power wiring between controller and rst
indoor unit:
• Minimum 18 AWG stranded, shielded cable
up to 164 feet (50 m).
• Ensure there are no gaps between the controller back cover and the mounting surface.
• Fill any holes in the wall behind the control-
ler to avoid false readings from inltration.
• Ground the shielded control wiring.
• Do not use a megger to test insulation.
Communication wiring between indoor
units:
• Minimum 18 AWG stranded, shielded cable.

Connecting to One Indoor Unit
Connect the controller to one indoor unit main control board using 4-conductor shielded 18 GA
cable. Connect to terminals 12V,COM,HA,HB. See Figure 1.

Connecting to Multiple Indoor Units
Connect the controller to multiple indoor units, up to 16. Use 4-conductor shielded cable to connect
to the rst indoor unit, then daisy chain control wiring to each indoor unit using the HA/HB 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.
