Hi, this is my first post, so all help will be very greatfully received.
I have an Ideal Elan 2 RS230 boiler and Honeywell ST699 control set. All installed when my house was built in the early 90's.
Problem
The boiler will not fire the main burner when the heating or water is supposed to be on.
Known Secondary Faults
The Honeywell ST699 programmer is a bit dodgy. The clock keeps jumping about all over, although it does seem to switch the heating when 'continuous' is selected.
The hot water does not heat up off the main boiler. I believe this is due to a leak I had damaging the 3 port valve, locking the flow to the central heating circuit only. Immersion heater used since that fault.
Other Points
-The house has been left empty for about 12 months, with the heating used very little in this time.
-When the heating is switched on, the water pump is working.
-The pilot light can be restarted when the boiler has been shut down.
-The temp thermostat does switch the heating(pump) on and off.
-The tank thermostat does switch the hot water(pump) on and off.
Can anyone point me in the direction on this one?
Thanking you, John
