What I can't work out, is why a boiler designed to work from the input to the ebus, would be altered to work on a mark/space ratio
But he already has a ebus type controller, he clearly shows wires to ebus, so why down grade?To increase the number of places the boiler can be sold.
The aim is to male it "compatible" with both the most complex of control systems the simplest bi-metallic ON-OFF thermostat.
So many people looking for a new boiler have bi-metallic ON-OFF thermostats and would not want to pay extra to update their control system if the boiler could not be controlled by their existing controller
Heating signal goes off, Hive Receiver led should flash for a bit, then make a click noise, then rad symbol on front of boiler should flash for a bit as the boiler “runs on” to clear its heat.
The run on period will depend on the heat left in the heat exchanger.
