Options
Operation Control
(*1): Electrical heater and humidifier are field supply. These parts should not be installed inside the equipment (refer to installation manual EKRP1B2A)
(*2): If installing an electrical heater, an option PCB for external heater (EKRP1B2) for each indoor unit is required.
(*3): An electrical heater can not be used for VRVsystem cooling only.
(*4): Mounting plate KRP4A96 is required for these options. Maximum 2option PCB’s can be mounted.
(*5): Decoration panel option EKBYBSD is required for direct mounting of the decoration panel on the unit.
