Fiesta mk8 hvac control panel

Hi folks

I was trying to retrofit some oem recaros with heating elements to my fiesta, all done, all the plugs were already there, except for the fuse box, which I need to upgrade in order to turn them on.

I also fitted the hvac control panel with the switcher for the seats ( H1BT18C612hk) which i think it’s an European spec, the original one was an h1bt-18c612-aj

all the flaps works, ac, ecc, except for the temperature setting wheel, which on Lo blows out really hot air and in Hi blows cold air

when driving, with the blower turned off, I can feel hot air coming out the vents instead of nothing or cold one.

what can that be? may it need just a reprogram? how can I do it?

when putting on the oem one, it starts to works fine, cold air on Lo and hot on Hi

There is a thread or two over at FMods about HVAC in Fiestas and issues. https://www.fmods.net/community/index.php
