Euroster 11 E

Product detailed description

The Euroster 11 E is commonly used in residential and commercial buildings to regulate circulation pumps in central heating and domestic hot water systems. It is typically installed in mechanical rooms, boiler houses or utility areas where access to electrical and hydraulic systems is required. Installers working on low-pressure heating circuits benefit from its programmable settings and anti-stop feature, which prevents unnecessary pump cycling. This unit is ideal for systems requiring precise temperature control and reliable pump operation under varying load conditions.

Correct installation ensures stable system performance and minimises the risk of overheating or underperformance. The device should be mounted in a location free from direct sunlight and moisture, with ambient temperatures within the operational range. It is essential to verify the compatibility of the connected pump and ensure that the electrical supply matches the unit’s requirements.

Technical parameters

The nominal load of 3 A at 230 V allows the thermostat to control standard circulation pumps used in heating applications. The temperature regulation range of 10°C to 80°C makes it suitable for both space heating and domestic hot water systems. The 1°C accuracy and 2–10°C hysteresis ensure stable operation and reduce unnecessary switching. These parameters are critical when selecting the device for specific system configurations and pump capacities.

Installation and connection

Mounting is performed using wall-fixing brackets provided in the package. A mounting template is included for accurate alignment. The device requires a 230 V AC supply at 50 Hz and must be connected via a dedicated circuit. The input and output wiring must be verified for correct polarity and secure connections. A common mistake during installation is incorrect positioning of the temperature sensor, which can lead to inaccurate readings. Always check the sensor placement and ensure it is in contact with the pipe or fluid being monitored.

Compatibility and accessories

The Euroster 11 E is compatible with standard central heating and hot water circulation pumps. It requires a separate temperature sensor and mounting hardware, both included in the package. Additional components such as external controllers or expansion modules are not required for basic operation. For alternative solutions, consider the AVANSA TH 2A thermostat, which offers similar functionality in a clamp-on design.

Technical background for designers

The Euroster 11 E operates using a microprocessor-based control system that processes temperature inputs and activates the pump accordingly. The anti-stop function prevents the pump from stopping due to minor fluctuations in demand, maintaining a minimum flow rate. The housing is made of durable plastic with an IP40 rating, suitable for dry indoor environments. The integration into the system depends on the correct configuration of the pump curve and the thermal characteristics of the installation. Long-term efficiency is affected by the stability of the power supply and the accuracy of the temperature sensor.

Service and operation

Periodic inspection of the wiring and sensor connections is recommended to ensure continued performance. Check for signs of overheating, especially at the terminal block. No scheduled service intervals are specified in the documentation. In the event of erratic operation, verify the sensor placement and recalibrate if necessary. The device does not require routine maintenance beyond visual inspection and cleaning of the display area.

Frequently asked questions

Can the Euroster 11 E be used with a three-phase circulation pump?
No, the device is designed for single-phase 230 V AC systems. Three-phase pumps require a different control solution.

Is the temperature sensor included in the package?
Yes, the thermostat is supplied with a temperature sensor, mounting hardware and instructions.

Can the Euroster 11 E be programmed for different time schedules?
Yes, the programmable function allows setting different temperature and operation profiles depending on the system requirements.

Does the device support remote monitoring or control?
No, the Euroster 11 E is a local control unit without remote communication capabilities.
