Wire for installing thermostat?
Just moved into a new place. I have a Biasi Rvia Advance HE M1100 combi boiler and need to install a thermostat as the previous owners (helpfully) removed the one that was previously there.
Looks to be a pretty simple job to install a receiver, so I bought a Drayton RF901 wireless themostat.
Unfortunately it doesn't come with any cabling, so what kind do I need to buy to connect the boiler to the backplate? It's opentherm if this makes a difference.
