S2
Standard solar system with 1 store, 1 pump
and 3 sensors. When the OHQM function has
been activated, sensor S3 (top tank) has to be
used as a solar fl ow sensor. This sensor must be
mounted on the solar fl ow line as close as possi-
ble to the tank. This allows a more precise heat
quantity balancing. Solar return sensor S4 and
solar fl ow sensor S3 are used now as reference
sensors.
