Can you run more than one extension boxes off the same system
I have a conventional boiler/radiator setup in my house and an additional zone using a Salus RT500RF (TX) controller for underfloor heating in an extention.
To control this underfloor heating; is it possible to add an additional extension box, in place of the sender, with a awireless thermostat.
This way I can control the whole house in one system
Hope you can help
