My Honeywell smartfit system has stopped heating the water up. Over the weekend I drained my CH system with a view to flushing it out. I isolated the boiler, (turned off the power) and drained my CH system. I added the cleaner to the expansion tank and refilled the system. My CH works perfectly and actuator on top of the pump seems to be working fine but when I set the room controller for HW only the boiler doesn't light but the room controller shows the boiler is lit. If I set the room controller to CH the boiler lights and rads get warm. It seems as though I need to reset my system but am unclear on how to do this.
Also there are no fault codes shown on my room controller
