The controller calculates the temperature difference between
collector sensor S1 and tank sensor S2. If the difference is
larger than or identical to the adjusted switch-on temperature
difference (DT O), the solar pump will be operated by relay 1,
and the tank will be loaded until the switch-off temperature
difference (DT F) or the maximum tank temperature (S MX)
is reached.

Sensors S3 and S4 can optionally be connected for
measurement purposes.
If energy metering (OHQM) is activated, sensor S4 has to be
connected as return sensor.
If the drainback option (ODB) is activated, relay 2 can be used
to operate a booster pump by activating the booster function
(OBST).
