If your heating system has developed a fault, it will be displayed and indicated
by the flashing red fault indicator A.
You can check the fault code on the display and then notify your heating con-
tractor accordingly. This allows your contractor to better prepare for the service
call and may save additional travelling costs.
Press the following keys:
1. a/b to display further faults, if
several faults exist.
2. d to acknowledge the fault.
The fault message will be displayed

not been rectified. The red fault indi-
cator flashes until the fault has been
rectified.
