Y plan denergise 3 port valve after CH
The Y plan system maintains power to the 3 port valve after CH has been on (but water off/not called for), whilst 3 port valves can cope with this they do use a small amount of energy and some hum rather annoyingly.
Idea: When the Tado turns off the CH it could momentarily call for the HW only to denergise the valve returning it to the HW only ('off') position, this would reduce energy consumption and improve lifetime of 3 port valve.
