    Do you have the manual for the Stadler WD23-DHW to compare functions? I can send you a copy if you don't.
    That's a fairly standard outdoor reset control for both boiler and mixing, with DHW priority. I'm sure tekmar has some comparable options - their 402 is more sophisticated but covers those functions.

    Does anyone have the WD23 DHW manual please…I see other have asked and I'm in the same situation… an older house with a update Vissmann boiler but older Stadler controller that doesn't seem to kick the boiler on when temperature is calling for hit. I have to switch the WD23 controller to manual (waving hand) and the heat then goes to the 10 zone manifold. I just has the Vissmann yearly serviced and a new honeywell mixing valve replaced…so everything is good…I believe either the controller is suspect or the outside temp sensor is busted.
