Hi Chris,
I`m trying to replicate your work(http://wiki.crowe.co.nz/Mitsubishi%20Heat%20Pump.ashx) using an arduino ethernet with a mitsubishi(heavy industries) heat pump.
My aim is to remote(LAN/http) start the "sleep" mode, which is the button left down side on the remote. In heat mode the heat pump is going to a sort of low power mode over the course of a few hours and decreases the room temperature to 13°C. Sleep mode goes for a maximum of 10 hours which is exact what I need.
My remote(RKW502A200B) is nearly the same as your's.

I was wondering if you had probably mixed up the fanspeed mode and the power modes of your heat pump.
These are two different settings, see your mitsu manual. There is normal mode, high power and ECO mode.
Only in normal mode I can choose the fan speed. -
When I use the timer buttons "sleep" "on" "off" the raw code jumps from 180 to 255.
Can you replicate this?
Thanks for your awesome work on this remote code!
