QAD 2012 contact temperature sensor
When the temperature at the cylinder temperature sensor falls below
the set value, the circulation pump for cylinder heating starts and the
DHW cylinder is heated.
The flow rate of the heating water is controlled via the return temper-
ature (flow control). This results in optimum stratification of the buffer
cylinder with sustained high temperature at the cylinder flow. The
heating periods (individual day and seven-day program) can be adjus-
ted via the integrated time switch.
