Climate controle unit
 

Hi all,

I want to change my climate control unit, as most of the knobs are failing and the pixels are dead.

Now i found a complete unit, but the seller is saying that the serial number has to be the exact same one, is that really true?

My unit is ending at 899 and from the seller 898..

Do you have auxiliary heating?

I believe unit ending 898 does not support auxiliary heating.

Yes i have that, indeed

This era aux heater is K-bus controlled (instead of voltage control) so unlikely any hardware differences, just a matter of coding.
