Electrical connection

• Connect the boiler to the fused (3 amp) switch spur unit
adjacent to the boiler.
• The switch unit must always be accessible.

When the switch spur is on the following components of this
appliance can be live (230 V):
• electrical connection gas combination block;
• most parts of the control unit;
• ignition transformer;
• X1, X2, X4, X5, X6 and X7 terminal strip;
• 230 V supply cable connection.
2.6.1 The control unit
The Remeha Avanta 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
59970LTGBW7H011
controls and protects the boiler.
The maximum rated input of the boiler is 150 W. 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 ter-
minal). 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 03.
