N322S RS485 24V Differential Temperature controller Solar Heating The N322S is an advanced differential temperature controller specifically engineered for solar water heating systems, optimizing energy efficiency by activating water circulation based on the temperature difference between solar collectors and storage tanks or swimming pools. Equipped with two integrated NTC temperature sensors, this controller features dual relay outputs—a main SPDT relay for pump control (16A resistive) and an auxiliary SPST relay for booster functions—providing comprehensive system management. A key benefit is its proactive protection system, which includes programmable setpoints to prevent both pipe freezing during cold conditions and dangerous overheating, ensuring system longevity and safety. With its bright 3½-digit LED display, adjustable hysteresis, and sensor offset calibration, the N322S delivers precise control tailored to specific installation requirements. Available in standard, 24V DC, and RS485 Modbus communication models, this robust controller features an IP65 front panel for reliable operation in diverse environmental conditions.
