Installation at a Glance

This manual covers the installation and setup of the MHK2 Remote Controller with Mitsubishi Electric

indoor units.
Before you begin, you must attach the cable to the CN105 connector on the indoor unit control

board, then follow the steps in this document.

Note:

Remote Controllers are linked to specific indoor units. Each indoor unit must have a

dedicated Remote Controller and Wireless Receiver.

Note:

Your device's PIN code is your date code added to 1234. For example, a date code of

2010 plus 1234 would give you a device PIN of 3244.
