Avansa 110 R

Product detailed description

The AVANSA 110 R is commonly used in central heating systems, particularly in multi-circuit applications such as boiler rooms, heat pump installations and district heating systems. It supports the automation of circulation pumps in response to temperature changes within the system, ensuring efficient operation and energy conservation. Installers typically encounter this device in domestic and commercial buildings where precise pump control is required to manage multiple heating circuits separately. The thermostat is suitable for environments where ambient temperatures vary significantly, making it appropriate for both indoor and semi-outdoor installations.

In typical installations, the thermostat is mounted near the boiler or heat exchanger and connected to the pump motors via standard electrical wiring. The device operates by monitoring the temperature of the heating medium and activating the corresponding pump when the set threshold is reached. This helps maintain stable system performance while reducing unnecessary motor runtime, which in turn lowers energy consumption and extends the mechanical life of the pump components.

The temperature measurement range of 0 to 90°C ensures accurate readings across most heating fluid temperatures. The pump temperature settings allow independent control of two circuits, with setting I from 5 to 80°C and setting II from 10 to 80°C. The maximum sensor temperature of -10 to 120°C ensures durability under extreme conditions. These parameters help determine correct application and prevent overloading or incorrect operation due to mismatched system requirements.

Installation and connection

To install the AVANSA 110 R, locate it close to the controlled equipment and ensure it is mounted vertically to avoid interference with internal components. Connect the power supply using a 230 V AC line with a tolerance of ±10%. Verify that the switching current does not exceed 6 A per circuit. Use standard electrical conduits and connectors rated for the specified voltage and current levels. Ensure all connections are secured and insulated against mechanical strain and environmental exposure. Common installation errors include incorrect polarity of the control wiring, improper mounting orientation, and failure to verify ambient temperature limits during site assessment. Always confirm that the installation location does not exceed the -10 to +50°C operating range to prevent damage to the internal electronics.

Compatibility and accessories

This thermostat is compatible with single-phase AC pumps and boiler controls operating at 230 V 50 Hz. It works well with the Euroster 11 E and the wall-mounted AVANSA TH 2A thermostat as supplementary devices. When integrating the AVANSA 110 R into a larger system, ensure that all connected components are rated for the same voltage and current specifications. Additional accessories such as junction boxes and mounting brackets should be selected according to the installation environment and local regulations.

Technical background for designers

The AVANSA 110 R operates by comparing the sensed temperature with the pre-set thresholds and triggering the pump motor accordingly. The device uses a solid-state switching mechanism that minimises contact wear and ensures consistent performance over time. The housing is constructed from durable thermoplastic materials suitable for long-term use in industrial and residential heating systems. To integrate the thermostat into a heating system, designers should account for the thermal inertia of the system and adjust the hysteresis accordingly. System efficiency is influenced by the accuracy of the temperature sensor and the responsiveness of the pump activation. Regular verification of the control logic and sensor calibration is essential to maintain performance.

Service and operation

Routine maintenance involves checking the integrity of the electrical connections and verifying the functionality of the temperature sensor. No scheduled service intervals are specified in the provided data. During operation, ensure that the thermostat remains unobstructed and free from condensation or dust accumulation. In case of irregular pump operation, verify the set temperature thresholds and inspect the wiring for faults.

Frequently asked questions

Can the AVANSA 110 R be used with three-phase pumps?
No, the thermostat is designed for single-phase 230 V AC systems only. Three-phase equipment requires a different controller.

Is it possible to adjust the hysteresis between on and off temperatures?
No, the hysteresis is fixed internally and cannot be modified by the user.

Can this thermostat be used outdoors?
No, the device is intended for indoor use only due to the specified ambient temperature range and lack of waterproof enclosure.

Does the thermostat support remote monitoring or digital interfaces?
No, the AVANSA 110 R is a basic mechanical thermostat with no provision for remote communication or digital feedback.
