6.4.3 Outdoor temperature for continuous rated operation (day)
If a heating circuit is in reduced operation (automatic mode), the circuit is automatically
switched to rated operation (day mode) when the outdoor temperature falls below 'Outdoor
temperature for continuous rated operation (day)'. When the limit value is exceeded (plus
0.5 °C hysteresis), reduced operation is restarted.
This function is activated at very low temperatures to avoid the building cooling down exces-
sively outside the times-of-use when outdoor temperatures are low.

6.4.4 Summer mode
Summer mode is activated depending on the mean daytime temperature (measured between
7.00 h and 22.00 h) during the desired period ('Earliest start date for summer mode' to 'Latest
stop date for summer mode').
If the mean daytime temperature exceeds the limit entered in 'Outdoor temperature for summer
mode' on the number of successive days determined in 'Delay of summer mode active' parame-
ter, summer mode is activated on the following day: the valves of all heating circuits are closed
and the heating pumps are switched off after t = 2 x valve transit time.
If the mean daytime temperature remains below the limit entered in 'Outdoor temperature for
summer mode' on the number of successive days determined in 'Delay of heating mode active',
summer mode is deactivated on the following day.
