event of a power failure occurring, the clock must be reset. An unsuitable setting or a clock error can cause data to
be deleted, recorded incorrectly, or overwritten.
2.1 Hours operation
Shows the total hours that the solar circuit pump connected to the controller has been in operation; various time ranges
are available (day…year).
2.2 Accounting
Metering of heat produced by the system.
2.3 Graphic overview
Provides a clear overview of the data listed under heading 2.1-2.2 in the form of a bar graph. Various time ranges are
available to allow comparison. Use the two keys on the left to scroll through the data.
2.4 Message log
Shows the last 20 events recorded by the system, indicating the date and time.
2.5 Reset/clear
Resets and deletes single analyses. The “all statistics” function clears all information except for error messages.
3. OPERATING MODES
Menu “3. Operating mode” allows selection of the desired
mode of operation:
automatic, off, or manual.
To quit the menu, press “esc” or select “Exit operating
mode”.
3.1 Automatic
Automatic is the normal operating mode of the controller.
Only automatic mode guarantees correct operation of the
system, taking account of the current temperatures and
the selected parameter settings! When restarted following a mains power failure, the controller will revert automatically
to the operating mode last selected!
3.2 Manual
The relay — and the component connected to the relay contacts — are switched on or off by pressing a key, regardless
of current temperatures and parameter settings. Measured temperatures are also displayed on the screen, for monitoring
and control purposes.
b
When “Manual" mode is activated, current temperatures and parameter settings are ignored by the controller. In this
situation, the system is liable to overheat and suffer serious damage. “Manual” operating mode must be used only
by an expert for conducting functional tests of short duration, or when setting up the controller!
3.3 Off
b
Selecting “Off” mode, all functions of the controller will be deactivated. This should be avoided normally, as it could
cause the solar collector or other system components to overheat, for example. Measured temperatures continue
to be displayed so that the overview remains available.
3.4 Fill system
b
This special operating mode is intended only for filling purposes when using a special “Drain Master System”, which
employs a fill level contact wired in parallel to collector sensor S1. Follow the instructions on the display when filling
the system. Be sure to deselect the Drain Master System once the fill is completed!
4. SETTINGS
The parameters essential to normal operation of the con-
troller are presented in menu “4. Settings”.
To quit the menu, press “esc” or select “Exit settings”.
