Flow temperature during the last 28 days

In the graphical overview the characteristics of the outdoor and flow temperature during the last 28 days is shown. The right but-
ton changes the unit of time (days) and the two left buttons scroll through the diagram.

Operating hours

Here the operating hours of the heating circuit and other switch or signal outputs are displayed. This is the entire time the heating
circuit pump and other switch or signal outputs were active. The displayed date in this menu is the date of the last deletion. From
this date on the current count is added.

Error messages

Display of the last 15 errors in the system with indication of date and time.

Reset / Clear

Resetting and clearing the selected statistics. Selecting ‚all statistics‘ clears everything except the error log.

3. Times

Settings for time, date and operating times for the heating circuit.

The associated temperature reference values are
specified in Menu 5, ‚Settings‘.

Time & Date

Serve to set the current time and date.

For system data statistics it is essential for the time to be set accurately on the controller. Please note that the clock
continues to run for about 24 hours if the mains voltage is interrupted, and afterward must be reset. Improper oper-
ation or an incorrect time may result in data being cleared, recorded incorrectly or overwritten. The manufacturer
accepts no liability for the recorded data!

Daylight saving time

If this function is activated, the controller automatically changes to winter time or summer time (DST, Daylight Savings Time).

Heating Circuit (Day)

This menu is used to select the daytime mode times for the heating circuit; three time periods can be specified for each weekday
and copied to the following days.

Unspecified times are automatically considered to be night-time mode. The set times are only taken into account in the
‚Automatic‘ heating circuit operating mode.

Heating Circuit Comfort

This menu can be used to select three time ranges for each day of the week in which the heating circuit is supplied with an
increased comfort temperature, e.g. for quick heating in the morning.
