The S-150 controller is designed to control the circulation of the central heating water. Its role is to start the pump if the temperature exceeds the set value and to stop it when the temperature drops below the standby level. This prevents unnecessary operation of the pump, allowing energy savings and extending the pump's lifespan.

Key features of the controller include:

• Adjustable operating temperature: 0°C–99°C
• Thermostat function: Allows setting temperature for stopping and restarting controlled devices.
• ANTI-FREEZE function: Activates the pump when the ambient temperature drops below 5°C.
• Features 2 LED displays: The upper display shows the current temperature, while the lower display shows the standby temperature.

Technical specifications:

• Power supply voltage: 230 V / 50 Hz ± 10%
• Power consumption: Operating temperature: -10°C–40°C
• Sensor type: Robust
• Sensor cable length: ~ 1 m
• Power cable length: ~ 1 m
• Pump cable length: ~ 1 m
• Output: 230V/50Hz
• Maximum output current: pump 1A (resistive load)
