eration is then blocked for two minutes. This test is repeated
automatically when the unit is switched on again, provided
that the unit has not been in burner mode for 10 minutes.

Tips/hints for the new ecoTEC/1-5
Electronic heat engine
–
You don't need any tools, just use the relevant diagnostic
points, e.g. D.000, D.085, D.146 - D.147, D.156 - D.157,
D.164.
Intelligent hydraulics
–
Yes, there is a bypass, but it has a different task. Use the
properties of the pump with D.170 and D.171 bis D.175.
User interface
–
Use the new possibilities of the interface, e.g. for the ex-
haust gas analysis use the new chimney sweep function.
