appears).
By using the “UP” and “DOWN” buttons
you can scroll through the other folders in
the menu: the folders are indicated below
in the order they appear:
-SP1: Set point 1 setting folder or
-AL: alarm folder (if alarms present, with
exception of faulty probes/probe errors);
-SP2: Set point 2 setting folder.
-Pb1: probe 1 value folder;
-Pb2: probe 2 value folder;
The folders are present according to
the presence and configuration of the
associated resource.
