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.
If the maximum collector temperature (CMX) is reached, the
solar pump will be operated by relay 1 and the 3-way-valve

will be operated by relay 2 in order to direct the surplus
energy to a heat dump. For security purpose this will be
carried out only if the tank temperature is below the non-
adjustable emergency shutdown of 200 °F.
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.
