Digital room thermostat - 2Ax1; +5 °C to +40 °C IVAR.TAD B

Product detailed description

This digital room thermostat is suitable for installation in residential and commercial buildings where accurate temperature regulation is required. It integrates into conventional heating and ventilation systems, allowing installers to maintain consistent indoor climate conditions. The device is intended for use in environments with stable power supply and moderate humidity levels, ensuring reliable performance over time.

The unit is commonly used in rooms requiring individual temperature settings, such as offices, living areas, or service rooms. It connects to HVAC systems via standard wiring and requires minimal configuration during installation. The operating range allows for use in most indoor environments, excluding extreme temperature conditions.

Technical parameters

Installation and connection

Installation involves mounting the device on a flat surface and connecting it to the HVAC system according to the manufacturer’s guidelines. The wiring should be checked for correct polarity and continuity before finalising the setup. Common mistakes include incorrect sensor placement or poor contact between terminals, which can lead to inaccurate readings or system malfunction.

Ensure the device is positioned away from direct heat sources or drafts to avoid false readings. Verify that the NTC sensor is properly connected and shielded from external influences. During commissioning, test the response time and accuracy of the thermostat to confirm proper operation.

Compatibility and accessories

This thermostat is compatible with standard HVAC systems using 2-wire configurations. It does not require additional accessories for basic operation. However, for extended functionality, consider pairing it with compatible control panels or monitoring systems. No related products are available for this model.

Technical background for designers

The operating principle relies on resistance changes in the NTC sensor, which correspond to temperature variations. This analog signal is processed digitally to provide precise control over the connected system. The housing is designed to protect internal components from dust and moisture, while the low-power design ensures long operational life. System integration is straightforward, with minimal impact on overall energy consumption.

The service life is influenced by environmental factors such as humidity and exposure to corrosive substances. Proper installation and regular inspection help maintain efficiency and prolong the device’s functional lifespan.

Service and operation

No scheduled service intervals are required for this device. Routine checks should focus on verifying battery condition and ensuring all connections remain secure. Replace batteries when the device indicates low power or when readings become inconsistent. Avoid exposing the unit to excessive moisture or physical damage to prevent internal faults.

Frequently asked questions

Can the thermostat be used with radiant heating systems?
Yes, provided the system operates within the specified temperature range and uses a compatible 2-wire connection.

Is it possible to integrate this thermostat with a building management system?
Integration depends on the system’s compatibility with 2-wire thermostats and the availability of appropriate interfaces.

How does the NTC sensor affect accuracy?
The NTC sensor provides linear resistance changes with temperature, enabling precise control. Ensure it is placed correctly to avoid interference from external heat sources.

What should be done if the display becomes unresponsive?
Check the battery condition and re-establish all electrical connections. If the issue persists, consult the technical documentation or replace the unit.
