Control by Wired Controller (Heat)
5.4.1.5 Remote Cooling/Heating Change [ Input Setting: Code (07) ]
The cooling or heating operation mode can be changed by giving a contact signal from the outside to the
unit. Set this function to CN3 with a wired controller according to Section 5.4.2.1 “Function Selection Item.”
This function detects ON to OFF transition and OFF to ON transition. Of the commands by this signal and
a wired controller, the command given later is preferentially executed. An example of basic wiring and time
chart is shown below.
