Yes, it is typically possible to upgrade a Webasto 2000 STC rotary controller to a later generation digital controller timer. It is necessary to learn if you have a suitable wiring harness to allow this upgrade, highly likely if you purchased in the UK from a reputable Webasto dealer.See image from Webasto manual.

You need to have both x9a and also x9c 4 pin plugs to allow this upgrade. Please let me know, if you require further information please email sales@butlertechnik.com

Thank you,
