Avansa 110 Z

Product detailed description

The AVANSA 110Z is typically installed in central heating systems where separate control of heating and domestic hot water (DHW) circuits is required. It is commonly used in residential and commercial boiler rooms, especially in systems with storage tanks for DHW. The thermostat integrates into systems where the heating pump activates based on boiler temperature, while the DHW pump operates based on the temperature difference between the boiler and the storage tank. This device is particularly useful in systems where energy efficiency and sequential activation of circuits are important.

Installers working on multi-circuit boilers, heat pump systems, or systems with DHW storage will find this thermostat suitable for managing load prioritisation and preventing simultaneous operation of multiple pumps. The thermostat is designed for environments with fluctuating ambient temperatures and where accurate temperature-based control is essential for maintaining system efficiency and protecting components from overheating.

The AVANSA 110Z is rated for 230V 50Hz power supply with ±10% tolerance, making it compatible with standard European electrical systems. The adjustable hysteresis of 10–30 °C allows for fine-tuning the temperature difference at which the DHW pump activates. The switching current of 6A ensures it can handle typical heating and circulation pump loads. These parameters are essential for correct sizing and integration into existing systems.

Installation and connection

To install the AVANSA 110Z, begin by ensuring the electrical supply is disconnected and verify that the wiring corresponds to the system’s configuration. The thermostat requires a 230V AC supply and is connected to the heating and DHW pump circuits via standard relay contacts. Connect the boiler temperature sensor to the designated input and ensure the DHW storage tank sensor is correctly positioned within the tank for accurate readings. Check the polarity of the supply voltage and ensure all connections are secure and insulated. A common mistake during installation is incorrect sensor placement, which can lead to inaccurate readings and improper pump activation. Another frequent error is failing to configure the priority function correctly, which can result in inefficient operation. Always confirm the ambient temperature range (-10 to +50 °C) is suitable for the installation location to avoid performance issues.

Compatibility and accessories

The AVANSA 110Z is compatible with most standard heating and DHW pump systems that operate on 230V AC. It works well with conventional boilers, heat pumps and systems using storage tanks for DHW. For systems requiring additional temperature monitoring or control points, supplementary sensors may need to be installed. It is often used alongside the Euroster 11 E and the wall-mounted AVANSA TH 2A thermostat for extended control options. When ordering, ensure the correct mounting hardware and sensors are included. Additional sensors are required for DHW storage tank monitoring and should be specified separately. Installers may also need to order terminal blocks or extension cables depending on the system layout.

Technical background for designers

The AVANSA 110Z operates using a bimetallic or electronic temperature sensing mechanism, measuring the boiler and DHW tank temperatures and comparing them to user-defined thresholds. The thermostat compares the boiler temperature to the set point for heating and activates the corresponding pump when the threshold is exceeded. For DHW, the thermostat activates the pump when the boiler temperature exceeds the tank temperature by the set hysteresis value. The device is constructed using durable, temperature-resistant materials to ensure long-term reliability in fluctuating conditions. Its design allows for integration into both new and retrofit systems. System efficiency is influenced by the accuracy of the sensors, the hysteresis setting and the priority function configuration. Poor sensor placement or incorrect hysteresis settings can lead to unnecessary pump cycling and increased wear.

Service and operation

Routine service for the AVANSA 110Z involves checking the integrity of the wiring, verifying sensor connections and confirming the priority function is set according to system requirements. While the device does not require scheduled service intervals, any signs of erratic pump operation or incorrect temperature readings should prompt an inspection. Key checkpoints include testing the switching functionality of the relay contacts and verifying the display shows accurate temperature readings. If the thermostat fails to respond to temperature changes, the sensor or internal electronics may need to be inspected. No specific maintenance schedule is provided in the technical documentation, so service should be performed as needed based on system performance.

Frequently asked questions

Can the priority function be changed during operation?
Yes, the priority function can be toggled between ON and OFF during normal operation by pressing and holding the MENU button and using the arrow keys to select the desired setting.

Is the thermostat suitable for outdoor installation?
No, the AVANSA 110Z is designed for indoor use only due to its ambient temperature range of -10 to +50 °C and lack of weatherproof housing.

Can the thermostat control more than two pumps simultaneously?
No, the AVANSA 110Z is designed to control two separate circuits—heating and DHW—via two independent relays. Additional circuits require a separate thermostat or controller.

How is the hysteresis value adjusted?
The hysteresis value is adjusted through the thermostat’s menu interface after entering the setup mode. Use the arrow keys to navigate to the hysteresis setting and adjust the value within the 10–30 °C range.
