Power/Econo mode? #5

Open oldwindmill opened 5 years ago

oldwindmill commented 5 years ago

Good Morning/Afternoon/Evening.. I'm wanting to use something exactly like this to control my 2 MHI aircons. the larger (model escapes me right now) offers an eco mode which runs in a low power mode. One of the reasons i want to be able to control them is in the event my mains grid fails and i run on battery. - to maximise battery life i first want to reduce to eco mode and then off. Has anyone any idea what bitfields eco mode might use? (the remote control has a combined power/eco mode - 1 push give power mode, 2 gives eco mode). I guess i will have to monitor the unit for state change when i manually enter eco mode.

Eco and Power modes separate when trying to use IR codes, but Eco it's just -2.5 (heating) / -1.5 (cooling) from set temperature, so you can just lower the temperature. Power - max/min (heating/cooling) temperature + max fan.
