Wired room controller Tech ST-294V1 (model ST294V1BK) – wall-mounted wired room controller

The Tech ST-294V1 wired room controller (model ST294V1BK) is a wall-mounted interface designed for centralized control of room systems. As a hard-wired controller, it provides a stable connection to compatible automation equipment and building control systems, allowing management of temperature setpoints, operating modes and basic scene selection depending on system integration. The device is intended for both residential and commercial installations where a reliable, fixed control point is required.

Advantages

The wired connection ensures consistent communication and reduces interference compared with wireless alternatives. The wall-mounted format provides a permanent, easy-to-locate control point for occupants and maintenance staff. Its design focuses on integration with HVAC and building automation platforms, enabling straightforward control of temperature and modes through an established wiring topology. The controller’s simple interface supports everyday use without frequent recalibration or battery changes.

Suitable for

• Individual room temperature control in homes and apartments
• Zone control in commercial buildings, offices, and hotels
• Integration with HVAC systems and building automation panels
• Projects requiring a hard-wired, tamper-resistant control point

Key specifications

• Mounting: Wall-mounted design for fixed installation
• Connection type: Wired interface for integration with automation equipment
• Control functions: Temperature setpoint adjustment, mode selection, basic scene control depending on system support
• Intended environments: Residential and commercial indoor use
• User interface: Fixed physical controls suitable for daily operation

How to use

Install the controller in a suitable indoor location on a standard electrical box or mounting surface and connect wiring to the compatible automation or HVAC control bus following the system integrator’s wiring diagram. Once connected and powered through the building control network, set the preferred temperature setpoint and choose operating modes or scenes as supported by the integrated system. Use the physical controls to make adjustments and rely on the hard-wired connection for uninterrupted operation.

Recommendations

Position the controller at a comfortable height away from direct sunlight, drafts, or heat sources to ensure accurate temperature sensing. Coordinate installation and configuration with the building automation integrator to confirm compatibility and proper wiring. For areas with frequent access by different occupants, consider labeling or documenting mode presets to prevent unintentional changes.
