I have fitted a new Salus RT510TX to my Baxi Duo-Tec 28 HE combi boiler. I set up all the required programs. After pairing. The boiler switched on but will not switch off on any of the settings. I can turn off the boiler with the salus reciever using the on off switch on the unit. All lights on reciever are solid so paired to programmer. Will turn off boiler if i reduce setpoint temp. Somthing is keeping the little flame heating mode on (no 9 icon).So i would think as long as the flame icon is there the unit will never tell the boiler to turn off. Any help would be gratefully recieved.
