15.2.2Error 01

24 Volt short-circuit

disconnect voltage from the boiler and check the fuse F2

as a result of a 24 Volt short-circuit inside or outside the boiler the fuse F2 will have blown. This fuse is placed in the control unit and can be seen after the black covering cap is removed.

check the 24 Volt

connection

remove all plugs with 24 Volt connections such as: fan, pump, any three-port valve and 24 Volt plug to the connecting block.

check the

disconnected

components for short-circuiting

switch on power again to the control unit with the components disconnected. Reconnect the components, which have been checked and are working.

rectify the short- circuit or replace the short-circuited component
