had 3 logic boards blow over a 5 year period on a standard condensing Barcelona.
Replaced most recent 4 weeks ago .. and had to change out teh wiring harness as board design now changed (hopefully more reliable)
Since swap out I have had intermittant fault - every few days, boiler stops and signals 'Ignition Lock-out/ overheat' ... turning off/on resets it and it works OK until next time.
On old board the advice was to remove both Blue bridges.
On new board .. there are now 4 bridges (J1-J4)
When I received new board I called BAXI and they advised remove all 4 ... but since then found a Tech note that states:
System upto J1 In J2 In J3 In
75,000 Btu/hr
System upto J1 Out J2 Out J3 Out
100,000 Btu/hr
Thermal Store J1 In J2 Out J3 In
compatibility
Anybody know what purpose of J4 is ... and what it should be set to ? in case this is causing my intermittant problem.
Boiler is connected to Thermal store.
