Communication wiring connections
•
Communication wires connect through side of air handler and be 2 X 16 AWG shielded.
•
Use an approved connector at the cabinet of the unit to prevent pulling or shorting of control wires.
•
F1/F2 in the air handler must connect to the F1/F2 communication bus for that system between all indoor units, MCU’s,
EEV kits, and the outdoor unit.
ATTENTION
•
Control wire must be rated for 600V minimum.
•
Control wire insulation must be rated for temperatures up to 90°C.
1. Insert the wires through the holes of the right side on the top casing and through the cable connectors.
2. Connect the communication wires to the F1/F2 connection terminal with compressed ring terminals.
3. Connect F3, F4 (for communication) when installing the wired remote control. F3/F4 does not have screw terminals to
connect to. Locate white/blue wires in control box and remove the plug on the end (labeled). Connect with crimp wire
connectors or wire nuts. Up to 16 indoor units can connect to a single wired controller (group control). Compatible wired
controllers: MWR-WE10N, MWR-SH00N.
•
Below is an example how to wire the main system communication wires and wired controller wires.
•
The example below is for indoor units without accessory electric heat kits. If an accessory heat kit is installed in an
indoor unit, that unit must be on its own dedicated circuit.
• The sum of all indoor unit MCA must be below 10A on a single circuit. Refer to "Specification of Electronic Wire"
section for information regarding wire size calculation.
※ When Installing ELCB(MCCB + ELB) indoor unit, do not connect with other indoor units attached to other outdoor units.
