Resetting a Mitsubishi heavy hard wired controller

Turned the camera off because you need to wait about 5 minutes after resetting but it will clear any fault if the repair has been made.

Note: you can reset the whole unit ("CPU reset" - same as power supply reset) by pressing CHECK+GRILL (aka CHECK+BLACK DIAMOND icon).

Hi Craig, my Mitsubishi HI RC-E5 has a 1 hour set on the top right of the display which turns the air con automatically off after 1 hour. Any ideas how to delete this and have no restrictions?

Hi Craig, my thermostat controller is dead after a power outage. I've checked all fuses within indoor and outdoor units. I'm getting 240V to both units but no display on the thermostat.

Any ideas ?
