230V installation cabling questions
I'm getting my tado° Smart Thermostat tomorrow.
I want to install it by replacing the existing thermostat, which is connected to a Saunier Duval isotwin combination boiler.
The following images are of the cables going into the existing thermostat:
Note that the earth cable in the image was never installed.
What will be the cabling for the Smart Thermostat ?
Since the Smart Thermostat is powered by batteries, I assume the following:
- the blue cable from terminal 1 and the red cable from terminal 2 (i.e. 230V AC input) will be connected to the parking terminals (not used) on the Smart Thermostat baseplate
- the orange cable from terminal 5 will be connected to the COM terminal on the Smart Thermostat baseplate
- the brown cable from terminal 4 will be connected to the NO terminal on the Smart Thermostat baseplate
Do the experts agree with my assumption above ?
Many thanks !
