I want advice about what Tado parts I need and how to wire them to a 2 port 'S' plan system
I am trying to get variable temperature control and timing from a Tado controller. Present system:
Thorn EMI Olympic Boiler 38/50B (old but I am told simple)
Grasslin/Towerchron QE2 electronic 7 day timer (With a back plate)
Satchwell wired hall thermostat
The system has 2 motorised valves, hot water cylinder with a bimetal thermostat on the tank, a pump and I think it is called an 'S' plan .
I want to have control over the temperature set on the hall thermostat (the water tank thermostat is not adjusted)
Any advise on what parts to purchase and how to wire up would be appreciated.
