Tax included
The ST-02 controller is an advanced electronic device designed for precise control of the water circulation pump in central heating (CH) systems. The main task of this modern regulator is to automatically manage pump operation based on the current temperature of the heating medium. The device switches the pump on when the temperature exceeds the user-defined value and switches it off immediately after the boiler cools down, which usually happens after it is extinguished.
Using the Diamond ST-02 controller brings measurable economic and operational benefits. Thanks to intelligent management of duty cycles, the device prevents unnecessary pump operation, which translates into significant electricity savings. Depending on the intensity of boiler use, these savings can reach up to 60%. Furthermore, limiting the pump's operating time directly extends its service life, increasing the reliability of the entire heating system and reducing maintenance costs.
The product is equipped with a range of safety features that ensure the installation's security throughout the year. The Antistop system protects the pump from seizing during the summer by starting it periodically every 15 days for a short time. Meanwhile, the Antifreeze function protects the system from damage at low temperatures by forcing continuous pump operation when the temperature drops below 5°C. An additional advantage is the built-in audible alarm, which instantly informs household members of a dangerous temperature rise in the boiler above 90°C, allowing for a quick reaction and avoiding failure.

Specification
Supply voltage
230V AC / 50Hz +/- 10%
Power consumption
2 W (very low power consumption in standby and operating mode)
Temperature adjustment range
5°C - 80°C (possibility of precise adjustment of the pump activation point)
Temperature measurement range
0°C - 99°C (wide range of boiler status monitoring)
Hysteresis
2°C (constant temperature difference preventing overly frequent device switching)
Device operating temperature
-10°C to 50°C (stable operation in boiler room conditions)
Sensor temperature resistance
-10°C to 120°C (high-quality sensor resistant to extreme conditions)
Protection rating
IP-20 (protection against access to hazardous parts with a finger and against foreign objects with a diameter > 12.5 mm)
Sensor cable length
1.2 m (allows for free installation of the controller in a convenient location)
Antistop function
Yes; automatic pump activation every 15 days for 15 seconds to protect against limescale build-up and rotor seizure.
Antifreeze function
Yes; automatic pump activation in continuous mode after the temperature drops below 5°C, which prevents water from freezing in the pipes.
Alarm signalling
Audible alarm activated when the temperature on the sensor exceeds 90°C, protecting the boiler from water boiling.
User interface
LED display indicating the current temperature and function buttons for setting operating parameters. The intuitive menu allows for quick changes to the set temperature without the need for specialist knowledge.
Software and control
The built-in microprocessor control algorithm ensures setting stability and high repeatability of duty cycles. The system monitors the status of the temperature sensor and, in the event of its damage or disconnection, switches to emergency mode (depending on configuration) or signals an error. The software has been optimised to maximise energy savings while maintaining full thermal comfort in the building. The LED visual interface allows for real-time monitoring of the water temperature in the circuit, which facilitates boiler operation diagnostics.
