Two controllers to one indoor unit connection method
Figure 3.8
• For the two controllers to one indoor unit connection method, two wired controllers control the same indoor unit,
where one controller will be the
"Main"
, and the other be the
"Secondary"
. Refer to
"Field setting"
. The default
setting of the wired controller is set to main controller.
• This method is only available for two KCT-03 SR wired controllers.
3.5 Install Main Body of Wired Controller
Take the shielded wiring that has been pre-embedded in the wall and pass it through the wiring hole of the rear cover
of the wired controller. Once connected, connect the wiring to the terminal X1/X2 (CN2) of the wired controller, and fix
the wired controller to the rear cover. (see Figure 3.9)
Fix the wired controller correctly and firmly to the rear cover so that the wired controller will not drop. (see Figure 3.10)
