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.
Sensor S3 is used for a thermostatic function, which ope-

rates relay 2 for backup heating or heat dump purposes,
when the adjusted thermostat switch-on temperature
(AH O) is reached. This function can optionally be com-
bined with up to three adjustable time frames.
Sensor S3 can also be optionally used as a reference sensor
for the thermal disinfection function OTD.
Sensor S4 can optionally be connected for measurement
purposes. If energy metering (OHQM) is activated, sensor
S4 has to be connected as return sensor.
