The controller calculates the temperature difference bet-
ween collector sensor S1 and tank sensor S2. If the diffe-
rence 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 mea-
surement 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).
