Mitsubishi MHK2 kumo touch™ Wireless RedLINK Remote Controller Kit

The MHK2 kumo touch™ is Mitsubishi Electric's wireless wall-mounted remote controller for mini split and multi-zone indoor units. It uses RedLINK™ 3.0 wireless technology to communicate with a receiver mounted at the indoor unit — no low-voltage thermostat wire run to the wall required. The backlit touchscreen provides full control of temperature, mode, fan speed, vane direction, and scheduling. Two AA batteries power the controller; no C-wire or 24V power supply needed. Note: The MHK2 uses RedLINK 3.0 and is not compatible with MHK1, MOS1, MCCH1, or other RedLINK 2.0 wireless devices. If you are replacing an MHK1, verify your indoor unit is on the compatibility list below before ordering. kumo cloud® Integration: The MHK2 can operate on the same indoor unit as the PAC-USWHS002-WF-2 Wireless Interface 2 (sold separately). Both devices connect to the indoor unit's CN105 port — the Wireless Interface 2 provides a second CN105 connector for this purpose. A Wireless Interface 2 is required if you want to control the unit remotely via the kumo cloud app in addition to using the MHK2 wall controller.
