Step into a world where solar water heating is simplified, streamlined, and smart. The SR868C8 Solar System Controller is the quintessential device for those looking to take full control of their solar heating system with minimal effort and maximum efficiency. This isn't just an accessory; it's an indispensable ally in your quest for a sustainable and intelligent home.

Quick Read: What's the difference between the SR510 and the SR868C8?

Why the SR868C8 Stands Out:

  • Precision Temperature Management: Our controller goes beyond mere adjustments; it ensures your water is precisely heated, providing you with the exact temperature you need for your daily comfort.
  • Adaptive System Settings: Tailor your solar heating to match the season. The SR868C8 adapts to your unique needs, offering custom settings for that just-right level of warmth, regardless of the weather outside.
  • Proactive System Safeguards: With the SR868C8, you won't have to worry about system overloads or weather woes. Our controller preemptively manages your system’s safety features, keeping everything running smoothly and securely.
  • Robust Construction for Every Climate: Engineered to endure, the SR868C8 controller is your all-season safeguard against the unpredictability of nature, ensuring your system's longevity.
  • Economical Operation: Dive into energy savings as the SR868C8 optimises the efficiency of your solar heating system. Enjoy the dual benefits of lower energy consumption and reduced utility costs, while basking in the reliability of continuous solar energy.

In the box, you'll find everything you need to get started, including a comprehensive installation guide. Whether you’re a seasoned eco-warrior or just beginning your sustainable journey, our Solar Water Heater Controller is the upgrade your system deserves.

Technical Data

  • Model: SR868C8
  • Dimensions of Controller: 120mm x 120mm x 18mm
  • Power Supply: AC230V±10%
  • Power Consumption: < 3W

  • Suitable Power of Pump: 3Λ, ≤ 600W
  • Suitable Power of Electrical Heater: 1Λ, ≤ 1500W
  • Inputs:
    • 1 x Pt1000 sensor (<500°C) for collector (silicon cables≤280°C),
    • 2 x NTC10K, B3950 sensor (≤ 135°C) for tank, (PVC cable ≤105°C),

  • Outputs:
    • 1 relay for electrical heater
  • Ambient Temperature: -10~50 °C
  • Water Proof Grade: IP40

Main Functions

  1. Temperature Difference Function (DT O & DT F): Activates the solar circuit pump when the temperature difference between the collector and the tank reaches the switch-on threshold and deactivates when it drops to the switch-off threshold.

  2. Timing Heating (THET): Allows for the automatic integration of backup heating at predetermined times, maintaining a consistent water temperature.

  3. Temperature Protection and Regulation Functions:

    • EM Emergency Collector Temperature: Engages to stop the solar circulation pump if the collector temperature exceeds the safety threshold, reactivating when the temperature decreases.
    • CMX Maximum Limited Collector Temperature: Prevents overheating by controlling the collector temperature, deactivating the solar pump when the collector temperature is too high.
    • CFR Frost Protection of Collector: Protects against frost damage by activating the solar pump and additional heating when necessary.
    • SMX Maximum Temperature of Tank: Controls the maximum water temperature in the tank, preventing overheating.
    • REC Tank Re-cooling Function: Lowers the tank temperature by reversing the circulation when the maximum temperature is exceeded.
  4. Manual Heating: Allows for the activation of backup heating devices when the top tank temperature falls below the preset temperature, maintaining a consistent temperature.

  5. BYPA High-Temperature By-pass Function: Facilitates the transfer of excess thermal energy to other applications, maintaining a constant tank temperature and preventing overheating by using an additional pump or valve.
