The Mitsubishi MHK2 is the second revision of Mitsubishi's most popular wireless controller set, now available for M & P Series residential and light commercial units. This controller offers in-depth 7-day scheduling and an easy to read, backlit display.

The updated MHK2 can now be used in tandem with the Kumo Cloud wi-fi adapter, sold separately. No longer do you have to choose between internet and wireless control: you can use both!

The MRCH2 is the main body of the thermostat. This can be placed anywhere within 200 feet of the indoor unit and does not require line of sight. The ;MRC2 cable will connect to the CN105 connector on the indoor unit's control board. The other end of this cable will connect to the MIFH2 receiver. The MIFH2 should be placed on the right side of a wall mounted unit, in the pocket of a MLZ-KP cassette, or anywhere near the control side of a ducted or square cassette unit.
