Operating and Installation Manual for Solar Module VR 68 0020054784_0026
Temperature increases in the collector are therefore
detected more quickly and thermal energy is transferred
to the solar cylinder earlier by the solar pump if
necessary.
Time window
Three time windows can be programmed each day for
the heating, hot water generation and circulation pump
(see operating manual for VRC430/VRC 430f
Section 4.7.1).
A target value is allocated to each time window
programmed for the heating.
In the case of hot water generation the hot water target
temperature applies for all time windows (Screen
10
"Hot water parameters").
In the case of the circulation pump the time windows
determine the operating times.
In automatic mode the system is controlled is in
accordance with the specified values in the time
windows.
Circulation pump
Depending on the length of the pipe, there may be a
brief delay before hot water flows when the hot water
cock is opened. A circulation pump circulates hot water
via your hot water pipe. This means that hot water is
available instantly when the water cock is opened. Time
windows can be programmed for the circulation pump.
