The controller calculates the temperature difference
between collector sensor S1 and store 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 store will be loaded until the
switch-off temperature difference (DT F) or the maximum
store temperature (S MX) is reached.

Sensors S3 and S4 can optionally be connected for mea-
surement purposes. S3 can optionally be used as reference
sensor for the store emergency shutdown option (OSEM).
If heat quantity measurement (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).
