We're having the Fujitsu ARTG54LHTC ducted system installed into our new build. The installer tells me that even though there is a Wireless App available it requires disconnecting the Wall Controller as it uses the only available interface. They tell me the wall controller offers a whole lot of installer functionality not available in the app. They're unwilling to disconnect the controller.

At a minimum I'd like the ability to remotely switch on and off the system. Timers are great but there will always be cases when we're coming home as a family and may want to heat/cool the house before getting home.

 

1. Can anyone confirm if the installer is correct?
2. Is there is way to offer a wireless interface at the same time as the wall controller?
3. Is there an option of connecting an IR module to the system so I could at least use my RMMini3 to control it remotely?

Failing the above then a wifi power outlet could do the job but it's an ugly solution to what should be a simple problem.
