12 Service program
12.1 Introduction
The service program is used by the installation
engineer or service and maintenance engineer for:
Setting the hysteresis;
Displaying the error history;
Displaying the appliance history
;
Display the selected appliance
;
Switching the pump on or off;
Setting the service interval
;
Setting the display contrast
;
Setting the display backlight time;
Setting the display scroll speed
.
These sub-menus are briefly described in the
following paragraphs. If you are not familiar in general
with how to use the displays and menus, first read the
relevant section (7 "The control panel")
.
Note
The notation convention for the service menu is
identical to that of the main menu (11.1 "Notational
convention for menu-related instructions"). The
difference is, you use to bring up the service
program, instead of which brings up the main
menu.
12.2 Setting the hysteresis
If the preset temperature (SETPOINT) is higher than
the current water temperature, then the appliance
might not immediately start the heating
cycle (9.2 "The appliance's heating cycle")
. To prevent
excessively frequent switching on and off, there is a
heating margin. We refer to this margin as the
hysteresis. The standard setting for this margin is
2 °C. The heating cycle starts if the water temperature
drops to 2 °C below the SETPOINT and ends when
the water reaches 2 °C above the SETPOINT.
Set the hysteresis via:
:
HYSTERESE UP
The figure shows an example
Set the hysteresis via:
:
HYSTERESE DOWN
12.3 Displaying the error history
Display the error history as follows:
:
HISTORY OF ERRORS
The controller will display an overview of "Blocking
errors" and "Lock out errors". In both cases, the
electronic controller reserves 15 lines for the last 15
error messages. If there are fewer than 15 error
messages, an ellipsis (...) is displayed. The display
first shows the "Blocking errors". When is
pressed, the "Lock out errors" are then displayed.
The figure shows an example of "Blocking errors". In
this case, the text
HISTORY OF ERRORS
is followed
by
(B)
.
The figure shows an example of "Lock out errors". In
this case, the text
HISTORY OF ERRORS
is followed
by
(L)
.
Note
For an overview of all errors and the possible
causes, please refer to the relevant
chapter (13 "Troubleshooting").
