Combi boiler hot water control
Hello everyone.
A bit of pickle here with hot water control and i can't seem to find an answer to it. I have a vaillant ecotec pro (vcw 289 i believe) hooked up to tado via ebus. Works like a charm when it comes to heating, no issues here. But i have a problem with hot water control as it seems to have overtaken the control from the boiler and no matter the settings hot water allways heats up to 60°. What i've tested so far:
HW control disabled (with the pro app), temp on boiler set to 45°, water goes to 60°
HW off, water goes to 60°, can set any temp i want on the boiler, water goes to 60° anyways
HW set to 46° in the app, water goes to 60° BUT the boiler also shows 46° in the settings, this means the app actually changes this parameter
My dad has the same boiler at his place, once we hooked up tado to it it exibits the same problem.
Am i missing something?
