The N321S is a controller for solar heating applications. It drives a water circulation pump based on the temperature differential between the solar collector and the thermal tank (or pools).
The instrument has two NTC temperature sensor inputs and one control output to drive the water circulation pump. It also has functions that prevent pipe damage in winter and prevent overheating, avoiding pipe damage and thermal discomfort.
– Sensor input
– NTC thermistor, type 10 k @ 25 °C; measuring range: -30 to +105 °C
– Measurement accuracy: 0.6 °C
– Maximum error when swapping original NTC sensors: 0.75 °C. This error can be eliminated with the controller’s offset parameter
– Note: sensors are included with the controller, with 3-meter cables, 2x 0.5 mm², which can be extended up to 200 meters
– Measurement resolution: 0.1° in the –19.9 to 119.9° range, 1° in the rest of the range
– Output (OUTPUT1): SPDT relay; 1 HP 250 Vac / 1/3 HP 125 Vac (16 A res.)
