Page 3: Application Area / Device Features
1.1 Application area SDC 307 controllers are high-performance microprocessor-controlled units for controlling the functions of solar thermal systems. The SDC 307 perfectly controls solar power systems equipped with up to two collectors or two storage tanks and can be used for numerous system types. The controllers are designed for use in dry rooms as well as residential, business and commercial applications. -

The upper part of the housing is locked to the lower part using two latches. -
Page 5: Connections
3.3 Connections The following points must be followed for the 230V connections: ■ In case of a fixed mains connection, there must be a switch installed outside the controller that can disconnect the device from the mains power supply. This switch is not required if the mains supply is connected using a cable and an earthed mains plug. -

Page 15: Controller Functions
Controller functions 7.1 General controller functions The controller compares the temperatures of the various measuring points and optimally charges the storage tank. If the collector temperature exceeds the storage tank temperature, the solar circuit pump is switched on. Monitoring and protection functions ensure safe operation. -

7.1.3 Independent controller This function is reserved for output 3 and can be allocated the following functions: ■ Cooling ■ Heating ■ Difference controller The temperature sensor for the temperature source can be selected as required. Cooling If the measured temperature exceeds the target value, output A3 is switched on until the measured temperature falls below the target value hysteresis. - Page 17 "Programming" menu Display Meaning Typical set- Value range ting Switch-on temperature of the 20 – 90°C 40°C min 40°C heating function Heating function hysteresis 1 – 30K dT 10K min 0:00 Time frame 1(2,3): 0:00 – 23:59 0:00 1(2,3) Start max 23:59 Time frame 1(2,3): 0:00 –...

Page 18: Tube Collector Or Start Function
7.1.4 Tube collector or start function If this function is activated, the solar circuit pump is started for the entered time frame regardless of the actual collector temperature. This allows the medium to reach the measuring point to determine the collector temperature. "Basic Setup"... -
Page 19: System Protection
7.2.3 System protection If the collector temperature exceeds the collector protection temperature (see 7.2.2) by 10K, the solar circuit pump is switched off to protect the system compo- nents. If the collector temperature drops below the collector protection temperature, the solar circuit pump is switched on. The function is always activated. -
Page 20: System Monitoring
System monitoring If an error occurs, the flashing symbol is generally displayed. 8.1 Sensor monitoring The connected sensors and sensor cables are monitored for interruptions and short-circuits. Errors are indicated by the symbol. You can find the error source by scrolling up or down the Info menu. 8.2 Flow monitoring The controller is programmed to display a message if the flow is interrupted, e.g. -
