• Manual operating mode: yes
• Control based on floor temperature: yes, when a floor temperature sensor is used
• Communication: wired
• Built-in sensor: room temperature sensor
• Display: with temporary backlighting
• Power supply: 2 × AAA 1.5V

Precise Temperature Regulation

TECH ST-295 v3 enables room temperature control with an accuracy of 0.1°C. This allows the desired temperature to be set precisely and provides convenient control of room conditions.

Day/Night Mode

The thermostat features a day/night mode, allowing different temperature settings to be used depending on the time of day.

Manual Operating Mode

ST-295 v3 also offers a manual operating mode. In this mode, the temperature settings can be changed directly using the thermostat.

Control Based on Floor Temperature

The thermostat can control the temperature based on the measured floor temperature. This function is available when a floor temperature sensor is used.

Adjustable Hysteresis

The device allows the hysteresis to be set within a range of 0.2°C–8°C. This makes it possible to adapt the thermostat's operation to the requirements of a specific installation.

Display with Temporary Backlighting

TECH ST-295 v3 features a display with temporary backlighting, making it easier to read the displayed parameters in low-light conditions.

Wired Communication

ST-295 v3 uses wired communication with the controlled device. The thermostat is a wired, two-state room thermostat.

Battery Power Supply

The thermostat is powered by 2 × AAA 1.5V batteries. This solution allows the control unit to operate without the need for a mains power supply at the thermostat.

Technical Specifications

Application

TECH ST-295 v3 is designed for wired room temperature control. Thanks to the built-in sensor, it can control the air temperature in the room, while the use of a floor temperature sensor also allows control based on floor temperature. The thermostat offers day/night mode and manual operating mode.

Can the TECH ST-295 v3 control the temperature based on floor temperature?

Yes. ST-295 v3 allows control based on floor temperature when a suitable floor temperature sensor is used. Without an additional sensor, the thermostat uses its built-in room temperature sensor.
