Hello again,,Back in the summer i replaced my old Vaillant with a Potterton Heatmax 28HE, and got the engineer to connect my Salus RT500 wired programmer...It works brilliantly, however due to changing rooms around we need to move the programmer to a different room, and due to it being hardwired, it's gonna be a problem..So to my question . Will the RF version of the salus be suitable for my boiler ? From looking at the boiler , i don't think the transmitter is going to fit onto the front, so is it just a matter of wiring the transmitter to the wires that originally went to the wired stat and mounting it near the boiler ?..Thanks in advance
