Yes
I am heaving a problem , new build all the finctions from the boiler is reading o.k. the thermo stats hav been faulty from the beginning as the dial just swirl round 360degree so where is the lowest temp point and the highest ??? builder insists that this is not preventing them from working whereas inthe rooms the dials seem ok the heating is controllable,as much as underfloor heating is controllable .
