The EUROSTER 11/11C is an electronic controller designed for central heating (CH) systems, specifically to manage the operation of a circulation pump. It automatically turns the CH system circulation pump ON or OFF based on the water temperature in the CH system. This device is suitable for systems heated by either coal-fired or gas-fired boilers. The water temperature is monitored by a sensor strategically placed at the CH system inlet.
The primary function of the EUROSTER 11/11C is to optimize the operation of the CH pump. When the CH system water temperature rises above a user-defined set point, the controller activates the pump to circulate the heated water. Conversely, when the temperature drops below the set point, the pump is turned off. This intelligent control prevents unnecessary circulation of unheated water, which can lead to energy waste and faster cooling of the boiler water, especially in coal-fired systems where chimney air draft can accelerate heat loss.
A key feature for coal-fired boilers is the controller's ability to turn the pump OFF as soon as the boiler flame is extinguished. This prevents the circulation of unheated water, which would otherwise cool down the boiler more rapidly than the radiator water.
The controller is equipped with a knob for presetting the optimum CH system water temperature, typically around 40°C. For systems with gas-fired boilers, it is crucial to set the controller's set point lower than the boiler thermostat's set point. Additionally, the controller's set point should be set higher than the dew point to prevent boiler "sweat" (condensation) during the heating process.
The EUROSTER 11/11C also incorporates an "ANTY STOP" function. This preventative measure is designed to protect idle pump rotors and valves from seizing due to prolonged inactivity. After the heating season concludes, this function automatically activates the pumps and valves for 30 seconds every 14 days. For this feature to work, the controller must remain powered up.
The controller offers both automatic and manual operation modes.
Installation of the EUROSTER 11/11C requires careful attention to safety and should only be performed by qualified technicians due to the presence of hazardous voltages.
Important Installation Note: The controller must not be installed in locations where the ambient temperature exceeds 40°C.
The EUROSTER 11/11C controller complies with all requirements of the EMC and LVD EU Directives. The CE Conformity Declaration is available on the manufacturer's website.
The manufacturer encourages responsible disposal of the device at an electronic waste management facility when it no longer meets requirements. Electronic waste is collected free of charge by local distributors. Inappropriate disposal can lead to environmental pollution. Cardboard packaging should be disposed of at a paper recycling facility.
The device comes with a 24-month warranty from the sale date. Claims require the controller and warranty certificate to be supplied to the seller and are processed within 14 business days. Repairs must be performed by the manufacturer or authorized parties. The warranty is invalidated by mechanical damage, incorrect operation, or unauthorized repairs.
