Heating AquaStat for Hot Water Control
We have a hot water cylinder with a typical stat linked to a relay with a dial to set the maximum temperature.
Without OpenTherm we have to use the on/off hot water setting.
It would be a lot better to be able to replace this dumb unit with a tado unit (run from mains power as there is mains power at that unit) that acted with the app to turn the boiler on only when water dropped below a set temperature.
This would also allow us to reduce the temperature of the hot water to maybe 50C-55C for most of the week and do a sanitation 60C heat once per week.
It would also help with understandinghot water usage in the house (teenagers)..
