We finished a condo in Puerto Rico last year that had 7 split type AC units throughout. Since the original ones were put in by the developer 8 years prior and not continuously run, they were in bad shape and needed replaced, and I wanted to use a model that worked the best with a third party control system. The Fujitsu models were recommended by the HVAC people, but I couldn't find any interface (other than IR) to control these.
I found that most of the new Mitsubishi Mr. Slim models can use a module that plugs into the main board to give a control interface for any standard thermostat. We went with 2 different Mitsubishi models that support this (different sizes for different size rooms) after we found a contractor who does Mitsubishi AC.
I haven't integrated the thermostat interface modules yet, but plan to soon along with basic wifi thermostats that can all be tucked away under the outer cover. It's not the cheapest option (the interface modules are pricy), but I think it is the best option for these types of AC units for true 2-way feedback.
jerrywolf got a reaction from eddy.trochez in Control for Fujitsu Wall Mount AC unit?
