Charging pump controller
Single circuit solar controller as PV version The ANS21 or ANS21-L unit is a solar controller which has been kept deliberately simple when it comes to installation and operation. Both the collector and the tank temperature are indicated using light bars. The smooth changeover between the signal bulbs ensures precise reading of the temperature. The ANS21-PV is suitable for use in 12V or 24V direct current networks. Moreover, changeover to a charging pump scheme is possible. Features:
- Adjustable di erential temperature
- Overtemperature protection for the tank or minimumthreshold for boiler
- Separate display for collector or boiler and tank temperature
- 1 relay output
- Suitable for KTY and PT1000 sensors
- Sensor short circuit and open circuit detection
- Overvoltage protection at all inputs
- Collector overtemperature switch-o
- Cascade switching of two devices for a two tank solar system is possible
