never mind me beeing stupid
i just have to tell the CT-80 to switch to heat to get stage 1 (make sense)

one thing however i noticed ... the FAN and Compressor seems to trigger always at the same time .. i never see the fan is on by itself (unless i turn it on manually) .. this makes very little sense .. for het and cool mode as there will be always rest-energy left to blow out .. but somehow the CT-80 does switch Y and G off at the same time.




again .. the manual has zero hints regarding this type of programming.
