2.6.1 The control unit
The Remeha Avanta Plus has an electronic regulation and
control unit with an integrated ionisation flame detector. The
heart of the boiler control unit is a microprocessor, the 'abc ,
®'
which controls and protects the boiler.
The boiler is not phase sensitive. The maximum rated input is
between 115 and 180 W (depending on boiler type).
The boiler is fully pre-wired internally, all external connections
can be made using the terminal strips X5 - X7 - X9 and 230
V input (X2 terminal). See the diagram for the position of the
connectors and fuse (F2) on the control unit.
The most important properties of the control unit are summa-
rized in table 04.
