The SR501 Solar Controller User Manual provides clear instructions for setup, operation, and maintenance, covering all features, safety functions, and troubleshooting tips for un-pressurized solar water heaters.
How the SR501 Solar Controller Works
The SR501 Solar Controller manages the operation of un-pressurized solar water heaters by intelligently monitoring temperature, water level, and system conditions. It uses its built-in microcontroller and LCD display to:
Measure Tank and Collector Temperatures
– Monitors water and collector tube temperatures with ±2℃ accuracy.
Control Water Loading
– Automatically fills the tank based on preset schedules or temperature requirements.
Manage Heating
– Activates the heating element or backup heater to maintain constant water temperature.
Protect the System
– Provides anti-freezing, high-temperature, overflow, and low-pressure protection to ensure safe operation.
Enable Recirculation & Thermal Disinfection
– Controls water circulation and periodic disinfection to maintain hygiene.
Alert & Display Errors
– Uses beeper warnings and error codes to notify users of system issues.
With these features, the SR501 ensures your solar water heater operates efficiently, safely, and reliably, delivering hot water whenever needed.
