SM-16005-rev.2 5-13EXTERNAL INPUT/OUTPUT AND FUNCTION SETTINGNOTES:1. Wired Controller is required for this function.2. Refer to Table 5.1 for details of the required components.3. If multiple indoor units are connected to the same communication cable for wired controller, input thesignal to any of these indoor units.4. When the communication cable is not used in the twin, triple and quad combinations for simultaneousoperation, set this function only to the main indoor unit.Indoor Unit PCBWiring Diagram Example(Example: Remote Cooling/Heating Change is set to terminals 1 and 2 of CN3.)CN3X13P Connector32121COOLHEATX1PowerSupplySignal to terminals 1 & 2 of CN3 HeatCoolHeatCoolOperation Mode of UnitControl by Wired Controller (Cool)Time Chart(Example: Remote Cooling/Heating Change is set to terminals 1 and 2 of CN3.)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 theunit. 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 anda wired controller, the command given later is preferentially executed. An example of basic wiring and timechart is shown below.
