Afternoon all I'm sure this is so simple BUT having problems . Trying to replace an old. Danfloss RMT 230 with a new Drayton RTS8 Following the instructions every combination I try as blowing the 3A fuse for the controller . Any help much appreciated with sorting the wiring First image is the old Danfloss Second the new Drayton Programmer is Centaurplus C27 Thanks Tim
Blue is neutral. Red live. Yellow - 3. On the new stat. Was the old stat working? Does is still blow the fuse if you join the red and yellow together?
Thanks gents Boiler now firing and fuse not blowing, but thermostat although is "clicking" not affecting the boiler at all its constantly on regardless of temp on thermo
I’ve had reliability issues with this stat before. Let the stat heat up a little then see if it turns off.
