mjsx Posted June 22, 2023 Share Posted June 22, 2023 Bit of a long shot, but does any happen to have a Vitodens 100-W system boiler (type B1HF, so purchased in the last few years) combined with an EM-P1 pump extension module? Are you able to set and change the schedules for the time the recirculation pump activates via the app? I was expecting to see something like this (from the demo account mode): My plumber has installed this, together with a Grundfos COMFORT pump, but via my ViCare app I can only turn the pump on and off. Apparently the plumber's own app allows him to set and change schedules, but I'm not able to do this. Is this normal? Viessmann seems to have a slightly wacky system of only allowing accessories to be added by the plumber (even the thermostat seems to work like this) which seems pretty user-hostile.
