Mitsubishi Split and external thermostat

Matic | Posted in General Questions on

I’ve installed a Mitsubishi Split system (MSZ-FH25) in my sunroom. The temperature never reach the desired setpoint (because warm air raises to the top of the sunroom where the unit is installed). I would like to use wall mounted Nest thermostat and PAC-US444CN-1 Thermostat Interface to control it. However I would like to know if I would still be able to control vane directions and air purifier on my handheld remote control?  Will i still be able to use i-see sensor so the air flow avoid people in the room?

    I would get a real thermostat from Honeywell. They make thermostats with wireless sensors and even sensors to detect outside temps. They are in the $200-300 dollar range. Maybe I shouldn't criticize the Nest, but the pro techs tend not to like them. I don't think they are very robust, and why would you want to tell the internet how you have your thermostat set and when you are using the unit?

      Hi, thanks for the reply.
      Regardless of the brand of the thermostat I get, i am interested in which features of my FH sensor and control I lose when I connect the PAC-US444CN-1 (if any) and if i will still be able to control some feature of the unit itself using the handheld remote control.
