Page 3: Safety Requirements
Safety requirements: All installation and wiring work on the controller must only be carried out in a zero-volts state. The opening, connection and commissioning of the device may only be carried out by competent personnel. In so doing, all local security requirements must be adhered to. -
Page 4: Solar Thermal System
Solar thermal system function switch in position S+ (solar) pump The pump runs when sensor KS has a temperature of diff higher than sensor BS and BS has not exceeded the threshold max. Pump = KS > (BS + diff) & BS < max Collector excess temperature: if the collector temperature climbs above 130°C, the pump is switched off and only released again, if the temperature falls below 110°C. -
Page 5: Selection Of The Program And Sensor Type
The controller does not operate or operates incorrectly, if the incorrect sensor type is set. ALWAYS PULL THE MAINS PLUG BEFORE OPENING THE CASING! ANS 21 The selection occurs by means of a slide switch on the right border of the board. There is no access possible to the slide switch from outside. -
Page 6: Master - Slave - Function
Master – slave – function: Two ANS 21 controllers, can be connected via the data link. Consequently it is possible to charge two tanks, of which one tank is prioritised for charging by the "master". Both sensors are connected to the master. -
Page 7: Sensor Installation
Sensor installation: The sensors must be properly arranged and installed for the system to function correctly. Collector sensor (red or grey cable with connection box): Either insert the sensor in a pipe directly soldered or riveted to the absorber and extending out of the collector casing or screw the sensor onto a T piece on the end of the supply line’s collecting tube using an immersion sleeve. -
Page 8: Installing The Device
Sensor failures due to storms and static electricity are usually the result of improper grounding or overvoltage protection on the collector sensor. Pin configuration: Fuse 3.15 A 230V~ ANS 21 When using the master-slave function, the data link must be connected in-phase to both units (data to data, ground to ground). -
Page 9: Tips On Troubleshooting
Tips on troubleshooting: When the control system does not function properly on automatic mode, the function switch and the sensors should be checked. Version display: as the controller is connected, the version is temporarily displayed using the right tank LEDs (binary code - reading from the top down). A short-circuit or an interruption of a sensor are displayed directly on the control system. -
