New Tado. Central Heating working. Hot Water not working. Can anyone help, please?
I have a new Tado that I want to use to control our central heating and our hot water. My kit is a smart thermostat, receiver, and a bunch of smart radiator thermostats. It was installed by a professional gas engineer. It was installed yesterday.
The central heating is working fine however the hot water is not working at all. My problem solving:
- When I make actions in the app, the Tado Thermostat reflects the change. So if two independent devices are updating, the software is working correctly, I think(?).
- The Tado app can control the central heating. For example, if I boost the rooms, the Central heating light comes on the receiver and if I turn off the central heating, the light goes off. Therefore, the wiring for the central heating must be correct.
- However I can't find a way to get the Hot Water light on the receiver to come on. If I click in the App or on the smart thermostat, it has no impact. So... I guess this is a hardware issue with the Hot Water? Either the writing? Or the boiler? Or something?
I've found some other threads where people talk about Y systems and combi systems but I do know what these mean. Our boiler is a Vaillant Ecotec Plus 838 if that helps, and this is a picture of the current wiring:
Has anyone else had this problem and do they know how to fix it?
