Dynamically adjust opening percentage based on rest of system as well as heat demand
A couple of weeks ago I posted a suggestion that users be allowed to set the minimum opening percentage on the smart valves to alleviate water rushing noise. In a separate thread about vibration, a solution was suggested to remove the Tado valve from the radiator nearest the boiler because "…it can happen that the water being pumped by the boiler is creating too much pressure (especially when the valves are only slightly open by tado° Smart Radiator Thermostats / the boiler is set to relay)."
I tried this and it fixed my noisy radiators. But I now have a radiator that isn't smart and heats up when I don't really want it to.
If the system was able to open valves that are calling for heat to larger percentages as more valves are shut then the problematic condition (when the valves are only slightly open) would not occur and presumably likewise any noise/vibration wouldn't happen. Obviously this means that the room(s) in question would heat faster than normal but presumably it would be possible to adjust the hysteresis curve to compensate.
I guess this would only be useful in a system like mine where every radiator is controlled by a Tado valve and the boiler is set to relay.
