Heating Down Diagnostic Help Appreciated
Hi all
Struggling to get to the bottom of this one! The boiler is Worcester Bosch 24ri system, not combi. The controls are Honeywell 2 heating zones and cylinder zone. The boiler is not showing error lights i.e. the blue indicator light is constant, not flashing. The Honeywell stats are wireless but seem ok. When I up the stat temperature for either upstairs or downstairs heating, the base unit indicator light led illuminates and the appropriate motorised valve opens. I have had the covers off both and can either see or hear the click of the microswitch. I would be surprised if both had failed along with the hot water zone at the same time. Anyone know why my boiler isn't firing? Background...... Air seems to be affecting the upstairs rads, but they are reluctant to bleed despite standing water in the header tank. I turned the boiler off before all this as I was adjusting the auto bypass valve which sticks occasionally and causes pressure surges. Any comments or assistance appreciated.
