The advanced Diamond ST-03 controller is an intelligent device designed for precise management of pump operation in central heating (CH) and domestic hot water (DHW) systems. Thanks to the use of a modern microprocessor, the controller optimizes energy consumption and extends the service life of the pumps by eliminating unnecessary operation. The device is equipped with a clear LED display that informs the user about the current temperature parameters in the system in real time.
A key advantage of the ST-03 model is its dual functionality. The CH pump is activated automatically when the boiler temperature exceeds a user-defined threshold, which prevents the house from cooling down when the boiler is extinguished. In turn, the DHW pump operates based on an intelligent temperature difference algorithm (hysteresis). This means that domestic water is reheated only when the boiler has a higher temperature than the tank, which guarantees maximum heat exchange efficiency.
Installation safety is a priority, which is why the Diamond ST-03 controller has a built-in anti-freeze protection system. If the temperature drops below 5°C, the pump is started permanently, protecting the pipes from bursting. Additionally, the device has an audible alarm that immediately warns household members about dangerous boiler overheating (above 90°C). This is a comprehensive solution for every modern heating system, combining savings, convenience, and full control over home hydraulics.
The intuitive control panel allows for quick changes to settings, and the solid housing guarantees trouble-free operation for many years. By choosing the Diamond ST-03 controller, you are investing in the thermal stability of your home and a real reduction in boiler room operating costs.

Specification
Power supply
230V / 50Hz +/- 10% - standard mains voltage allowing for direct connection to the electrical installation.
Power consumption
2W - very low energy consumption in standby and controller self-operation mode.
Ambient temperature
From -10°C to 50°C - allows for installation of the device in unheated boiler rooms and technical rooms.
Pump output load
Maximum 6A for CH and DHW outputs - enables control of even powerful circulation pumps.
Temperature measurement range
From 0°C to 99°C - precise temperature reading in a wide spectrum of system operation.
CH temperature setting range
From 5°C to 88°C - flexibility in adjusting the moment of switching on the heating circuit.
DHW temperature setting range
From 20°C to 80°C - optimal management of domestic water temperature in the tank.
Sensor temperature resistance
From -10°C to 120°C - sensors resistant to extreme conditions prevailing directly at the boiler.
Sensor cable length
CH sensor: 1.2 meters, DHW sensor: 3 meters - ensures freedom of placement of measuring elements in the boiler room.
Adjustable tank hysteresis
From 10°C to 30°C - allows avoiding too frequent switching on of the DHW pump, which protects the device and saves energy.
User interface
The device is equipped with a digital interface with a high-contrast LED display, which allows for easy temperature reading even in poorly lit rooms. The control panel consists of function buttons allowing access to the configuration menu, changing set temperatures, and setting hysteresis. The controller software continuously analyzes data from two sensors (boiler and tank), automatically making decisions about starting the appropriate current outputs. The system has built-in priority and safety logic that operate independently of user settings (e.g., anti-freeze protection).
Additional functions
Audible alarm (buzzer) activating at 90°C, anti-stop function preventing pump seizure outside the heating season, LED signaling diodes informing about the operation of a specific pump.
