Function overview controller - SC3.10

Solar thermal systems

Controller SC3.10 for solar stations

The solar controller SC3.10 is completely mounted and preset so that only

the collector field sensor and the storage tank sensor must be installed and

connected.

The graphically animated LC display gives a quick and simple overview

on the solar installation and the operating conditions. Icons facilitate

programming the controller.

The controller comprises 17 preset systems and can be used in solar

installations with up to two collector fields or up to two domestic hot water

or buffer storage tanks. It is possible to use a solar transfer station with an

external heat exchanger and a tank for potable water or a buffer tank with

two loading areas.

The third relay output and a potential-free switch output for safety extra-low

voltage allow additionally individual control and alarm functions.

Not only temperature measurement, but also heat quantity balancing based

on flow calculation is possible by means of the sensors.With demanding

requirements, a pulse sensor or PAW FlowRotor can be connected for heat

quantity balancing.
