Terminals location and conceptual connection diagram
To connect the DIII-NET communication line, use the two terminals F1 and F2 under the label “DIII”. These 2 terminals have no polarity. An
example of connecting more than 2 air conditioning devices is shown in the following conceptual connection diagram.
CAUTION
Make sure that the wires you are connecting to the F1 and F2 terminals are not power wires.
Inadvertently connecting power wires to these terminals results in a failure of the air
conditioner or iTM plus adaptor.
