Customer Question

I have a Buderus Logano 124.
It is displaying the Heating Error sign on the readout.
As the manual stated, I reset by turning off and on. Adjusted the max temp to 140 degrees, and made sure the reset button on the front had not popped.
The boiler would run for a little after being switched on but would stop at different temps 95 deg or 120 degs.
Called a technician - at some expense he replaced the Honeywell aquastat thinking the contactor was shot. Worked whilst he was here.
Just went down four hours later to see the reading "Heating Error"again.

Are you talking about the temp on your indirect fired water heater? Do you have a GA 124 boiler?
