Why is my Mitsubishi Electric Controller heating system not reaching the set temperature?

If your Mitsubishi Electric Controller's heating system isn't reaching the set temperature, first check if a prohibit, schedule, or holiday mode is active and adjust the settings as needed. Also, the room thermostat may be located in a place with a different temperature than the rest of the house. If so, reposition it to a more suitable room. If these steps don't resolve the issue, it might be due to incorrectly sized heat emitters, and you should contact your installer.
