I've had Tado running over the past week with mixed results. The main issue was that when the scheduled water came on so did the heating. Not ideal when it's as warm as it is at the moment. Tado support (and various sources on the internet) suggested the 3 port mechanical valve, a common problem is the motor going so it cannot open/close the valve to direct the water. I have only owned the house for 6 months and the previous owners didn't look after it, the switch on the 3 port valve was set to manual rather than auto.
I ran out and replaced the motor in the mechanical part of the valve, hoped that would be the end of it. Not so.
Now (and periodically before using Tado) I cannot switch the hot water on. I have even put the old honeywell thermostat and programmer back on but it behaves exactly the same. When I put the hot water on continuous nothing happens at the boiler, yet if I switch the heating on continuous it fires up he boiler straight away.
I have tried the switch both on manual and auto and nothing seems to change it.
Any thoughts?
The 3 port motorised valve looks like this: http://www.honeywelluk.com/products.../V4073A-Motorised-Midposition-Diverter-Valve/
