The boiler display
Two boiler displays, “Good or Technical” see below.
Good
or standard read out.
During this reading the display will only show what
is necessary. Under normal circumstances the
display will give a Good reading. In case of a
fault this will be shown with, alternate display of
Good, with an E or BL code. See further "Errors,
maintenance and warranty" .
Technical
The second way is a technical read out. In normal
situations the following will be shown:
• on the left the status in which the boiler is active
(see bottom of this page);
• on the right the supply temperature in °F;
• the water pressure in the installation in PSI.
When a message ( E or BL code) is necessary this
will be shown instead of the technical read out.
To switch over from the Good-state to the
Technical read out (and vice versa):
- Press 5 sec. on the STEP-button.
