Menus 0, 1 and 7 are Viewing Menus: they only allow the information displayed to be
read, and not modifi ed. Via menu 0 it is possible to view the appliance operating data as
detected by the board in real time; Menu 1 shows the parameters that characterise the
operation of the appliance and their current values.
Menu 7 pertains exclusively to Potterton's Commercial Engineers.
To view the information contained in these menus, proceed as illustrated in the paragraph
"How to access the menus".
Menu 2 is an execution menu: it is used to reset the fl ame controller, reset errors and
manual defrosting control.
To perform these procedures, see Section 3.3 RESET OPERATIONS AND MANUAL
DEFROSTING on page 19.
Menu 3 is a settings menu: it allows the values displayed to be set. The correct values
of these parameters, for optimum performance of the appliance with the plant to
be used connected, have already been set during installation. In any case, to set
new values for the parameters, see Section 4.8 PROGRAMMING OF HYDRAULIC
PARAMETERS on page 34.
Menus 4, 5, 6 and 7 exclusively concern the installation technician and Potterton
Commercial Engineer.
Menu 8 may currently be selected, but not used.
Display and knob
The controller’s display can be viewed through the glass of the viewing hole on the front
panel of the appliance.
Upon activation, all of the LEDs of the display light up for approximately three seconds,
and then the name of the board, S61, appears. After around 15 seconds after the appliance
powers up, the appliance starts running if the required consent is available.
During correct operation the display shows, alternately, the following information: outlet
water temperature, inlet water temperature, and the diff erence between the two water
temperatures (see Table 3.2 Operating information on page 18).

If there are operating problems, the display shows, sequentially, the operating codes
corresponding to the problem detected. A list of these codes with their description and
the procedure to follow to bring the appliance back to correct operation is provided in
Section 8.1 MACHINE OPERATING CODES on page 67.
The knob is used to display or set parameters, or to execute actions/commands (e.g.: a
function or reset), when permitted.
