Thank you so much for clearly explaining the connections.

I'm replacing a thermostat, does anyone know if it's ok to use the existing floor sensor cable, or would it be essential to use the new one, as I take it you need to dig up the floor to install a new floor sensor? As it would be a lot easier to just use the wires that are already in. Thanks in advance
