Hi Al21, nice to hear from you
Well, those 2 wires on the wall come directly from the boiler, but they are only two and in the receiver there are more than two "holes" to connect them :?
I am not a technician but I guess they work as a switch, if the circuit is opened nothing...
Hi there
Just bought my RT500RF but when I unplugged the old thermostat and try to connect this one I realize I have only 2 wires in the wall... :roll:
Any ideas how should I connect it?
Regards from Madrid
