1. Heat Controller recommends using 600V THHN 14AWG/4
conductor unshielded stranded copper cable; however
local and national codes for wire should always be
followed based on your specific application.
2. The indoor unit’s terminal strip is located underneath the
electrical box cover panel.
3. Loosen the screws to remove the cover.
4. Pull the conductor through the rubber grommet of the
electric box.
5. Connect each conductor from the outdoor to the
appropriate terminal of the indoor unit based on the
labels of each terminal.
6. Be certain that none of the connections are crossed and
the wires are routed to properly match the outdoor
unit’s connections - wire color and location to and from
each terminal must be identical between the indoor and
outdoor terminal strips.
7. Ensure proper grounding.
8. Use cable clamp to secure the cable and provide a strain
relief.
9. Wrap any loose cables not connected with terminals with
electrical tape, so that they will not touch any electrical
components.
10. Foam can be wrapped around the cable insulation to
prevent any condensate.
11. After connections are securely made, replace the cover
panel to the electrical box and screw it on tightly.
ATTENTION: When more than one indoor unit is installed, the dip switches on the outdoor unit’s control board
can be set to determine which indoor unit is considered the master, while the others are considered slave units.
This helps to dictate which unit controls the system for better operation.
Note: Appearance of the board may vary, but similar dipswitches can be found on each outdoor board.
