hi there,

2nd post, again on air con 😉

we have 3 ducted systems, one of the room controllers has packed up, i know its the room controller as I swapped it for one of the others and all was well.

the units are carrier.  they have 3 wires into the back of the room thermostat controller, I guess one is prob for the fan speed and the other two the circuit.

does anyone know where to buy new controllers from?  I would like ones that are programmable for time on/off and obviously take 3 wires.  I bought a cheap one from leroy but they are only two wire.

I have written to half a dozen air con firms in the area but most dont reply, most want to come service everything first, which I dont mind once I have things working, but, right now I just want a new room controller (well three actually if I get the timer models)

thanks
D
