10.3 LEARNING LOOPS
The management of the delay time in “Automatic” mode is not ad-
justable. It is calculated using a learning loop that averages the last 5
switch-ons.
An increasing delay time is the symptom of a drop in output ow and
may therefore indicate a fault in the discharge installation (clogging, etc.).
11. GUARANTEE
Smart Control Box is guaranteed for 2 years for parts and labour, sub-
ject to correct installation, use and maintenance of the unit.
