Avansa 110 E

Product detailed description

The AVANSA 110 E is commonly used in residential and commercial boiler rooms to manage circulation pumps in heating systems. It is suitable for installations where temperature regulation of the boiler or heat source is required. Installers typically integrate it into systems with solid-fuel or gas boilers, where the pump should only operate when the boiler is active. This helps reduce unnecessary pump running and ensures energy efficiency. The device is installed in environments with ambient temperatures ranging from -10 to +50°C, making it suitable for both indoor and semi-outdoor conditions.

Its primary role is to optimise the operation of the pump by responding to temperature changes in the boiler room or heat source. When the boiler generates heat and the temperature rises beyond the set threshold, the thermostat triggers the pump to circulate the heated medium. Once the boiler stops and the temperature drops, the thermostat disconnects the pump. This prevents energy waste and mechanical wear on the pump. Additional functions such as anti-stop and freeze protection enhance long-term reliability in seasonal operation.

The AVANSA 110 E operates on 230V AC at 50Hz with a ±10% tolerance, making it compatible with standard domestic and industrial power supplies. Its switching current of 6A allows it to handle typical low-power pump motors found in heating systems. The temperature measurement range spans from 0 to 90°C, while the user can set the operating range between 5 and 80°C. These parameters are essential for ensuring correct sizing and compatibility with the pump and boiler system. The maximum sensor temperature of -10 to +120°C indicates the environmental limits within which the sensor remains functional.

Installation and connection

Installation involves mounting the thermostat in a dry, accessible location near the boiler or heat source. The sensor cable, 1.2 m in length, should be routed to a representative location for accurate temperature readings. Connect the thermostat to the pump motor using standard electrical wiring, ensuring all connections are secure and insulated. Check that the ambient temperature at the installation site falls within the specified -10 to +50°C range. Common installation errors include incorrect sensor placement, which can lead to inaccurate readings, or failure to account for voltage fluctuations beyond ±10%, potentially affecting performance.

Compatibility and accessories

The AVANSA 110 E is designed to work with standard single-phase AC pump motors rated for 6A or less. It is compatible with various boiler types, including gas, oil and solid fuel systems. For additional control options, installers may consider pairing it with external sensors or integrating it into a larger building management system. Related products such as the Euroster 11 E and the AVANSA TH 2A wall-mounted thermostat offer alternative configurations depending on the installation requirements.

Technical background for designers

The thermostat operates using a bimetallic or electronic sensing element that reacts to temperature changes. When the measured temperature reaches the set point, the internal relay closes the circuit to activate the pump. The materials used are selected for durability and resistance to thermal cycling. The integration into the system depends on the boiler’s control logic and the pump’s electrical characteristics. Proper ventilation and protection from direct heat sources are important for maintaining long-term accuracy and preventing premature failure. The anti-stop function and freeze protection add redundancy to the system, especially in unattended or seasonal installations.

Service and operation

Regular maintenance includes checking the integrity of electrical connections and verifying the accuracy of the temperature sensor. No scheduled service intervals are specified, but periodic inspections are recommended to ensure continued functionality. In cold climates, the freeze protection feature should be tested to confirm it activates the pump when temperatures drop below 5°C. If the pump fails to start despite the thermostat triggering, the issue may lie with the pump motor or wiring rather than the thermostat itself.

Frequently asked questions

Can the AVANSA 110 E be used with a three-phase pump motor?
No, it is designed for single-phase AC circuits with a maximum switching current of 6A. Three-phase motors require a different control solution.

Is it possible to adjust the temperature settings manually?
Yes, the thermostat allows manual adjustment of the temperature range from 5 to 80°C using the control dial or interface.

Does the thermostat have a digital display for monitoring temperature?
No, it does not include a digital display. Temperature monitoring must be done through external means or via the system’s overall performance.

How often does the anti-stop function activate the pump?
The anti-stop function switches the pump on for 15 seconds every 15 days to prevent mechanical lock-up during periods of inactivity.
