Avansa 2007

Product detailed description

The Avansa 2007 programmable room thermostat is commonly used in residential and commercial buildings for temperature control in heating and cooling systems. It is suitable for integration with radiators, underfloor heating, and HVAC units. Installers typically work with systems operating between 24V and 250V AC/DC, and the thermostat is designed for environments where precise temperature regulation is required. It supports both heating and cooling functions, allowing users to set different temperature levels for up to six daily intervals. The device is compact and lightweight, making it suitable for installation in standard wall enclosures without requiring extensive modifications to existing systems.

Its low power consumption and battery operation make it ideal for installations where wired power sources are not readily available. The thermostat is also equipped with a built-in pump protection function, ensuring that the boiler or pump is activated at least once daily to prevent system stagnation. This is particularly useful in systems that may remain inactive for extended periods, such as seasonal properties or unoccupied spaces.

The technical parameters of the Avansa 2007 are essential for proper system integration and sizing. The 8A switching capacity allows it to control a wide range of heating and cooling loads. The 24V-250V compatibility ensures it can be used with various types of HVAC equipment. The temperature range of 7–35°C in 0.5°C increments provides flexibility for different climate zones and user preferences. The IP30 rating means it is suitable for indoor use and not for outdoor or high-moisture environments. The NTC 10KΩ temperature sensor ensures accurate and stable readings, which are critical for maintaining consistent room temperatures.

Installation and connection

To install the Avansa 2007, first ensure that the power supply is disconnected. The thermostat is connected to the heating or cooling system using standard electrical wiring. The connection voltage must be between 24V and 250V AC/DC, and the current rating must not exceed 8A. It is important to verify that the system's wiring is compatible with the thermostat's input requirements. The device uses two LR6 (AA) batteries for internal operation and should be installed in a location free from direct sunlight or heat sources to avoid sensor inaccuracies. Common installation mistakes include incorrect wiring of the control circuit, which can lead to improper system activation or failure. Another issue is improper placement, such as near windows, doors, or heat-emitting appliances, which can affect the accuracy of temperature readings. Always follow the manufacturer's guidelines for mounting height and orientation to ensure optimal performance.

Compatibility and accessories

The Avansa 2007 is compatible with most boilers and HVAC systems that operate within the 24V-250V range. It works well with both radiator-based heating and underfloor heating systems. For optimal performance, it is recommended to pair it with compatible accessories such as wall mounting brackets and electrical junction boxes. Related products include the Euroster Q7 and Saswell SAS 908 7, which offer similar functionality and can be used as alternatives depending on the specific system requirements.

Technical background for designers

The Avansa 2007 operates using a NTC 10KΩ temperature sensor, which provides accurate and stable readings. The sensor's resistance changes with temperature, and this change is converted into a digital signal for display and control. The thermostat uses this signal to compare the current room temperature with the user-defined setpoint and activates the heating or cooling system accordingly. The device is designed to integrate seamlessly into existing HVAC systems and can be used with both single-stage and multi-stage systems. The IP30 rating indicates that the device is protected against solid objects larger than 1 mm but not against water or dust. This makes it suitable for indoor use in dry environments. The low power consumption of 1.3 mW ensures that the device does not place a significant load on the system's power supply. The use of LR6 batteries for internal operation allows for easy replacement and ensures that the device remains functional even during power outages.

Service and operation

The Avansa 2007 requires minimal maintenance due to its robust design and low power consumption. The batteries should be replaced when the device indicates low power, typically after several years of use. The thermostat should be checked periodically to ensure that the wiring connections are secure and that the temperature readings are accurate. If the device is not functioning correctly, it should be disconnected from the power supply and inspected for any signs of damage or wear. The pump protection function ensures that the boiler or pump is activated at least once daily to prevent system stagnation. This function is particularly important in systems that may remain inactive for extended periods. If the system is not used for more than 24 hours, the thermostat will activate the boiler for one minute at 12:00 PM to maintain system integrity.

Frequently asked questions

Can the Avansa 2007 be used with underfloor heating systems?
Yes, the thermostat is compatible with underfloor heating systems. It features a sensitivity setting of +0/-0.2°C specifically for underfloor heating, ensuring precise temperature control.

Is it possible to set different temperatures for different times of the day?
Yes, the thermostat allows for up to six daily temperature settings. Each setting can be configured with a different temperature in 0.5°C increments, making it suitable for both heating and cooling applications.

What type of power supply does the Avansa 2007 require?
The thermostat operates with a 24V AC/DC or 250V AC power supply at 50 Hz. It also requires two LR6 (AA) batteries for internal operation and memory retention.

How accurate is the temperature measurement?
The thermostat has a temperature measurement accuracy of ±0.5°C. This ensures reliable and consistent temperature control in most indoor environments.
