Change of e-prom
Cut the power to the boiler. Remove the front panel on the boiler so you can reach the backside
of the display. Gently remove the e-prom. Fit the new e-prom and gently push it into place.
Reassembly the front panel.
Check so that the marking of the
prom is set at the correct side.
Before shifting a e-prom make sure to write down all the settings that has been done
to the boiler. This since all the changes that has been done will be lost.
While mounting the e-prom make
sure that the ”legs” isn´t damaged
