Product information

Description

TECH ST-297V3 is a wall-mounted two-state room controller designed for on/off control of heating and HVAC equipment. The device features a 3 mm glass front panel in a black finish and provides a compact surface-mounted interface for simple binary switching of room temperature systems. Its minimalist appearance and flat glass surface suit domestic and commercial interiors where a discreet, easy-to-clean control panel is required.

Advantages

The glass front panel ensures a smooth touch surface that is resistant to wear and easy to maintain, while the two-state switching logic delivers straightforward on/off control without complex programming. Surface mounting simplifies installation on existing walls and reduces the need for recessed boxes. The black finish provides a neutral appearance that integrates with a variety of interior styles.

Suitable for

On/off control of radiators, convectors, or electric heaters

How to use

Install the controller on a suitable flat wall surface at a convenient height for occupants, following electrical safety standards and local regulations. Wire the unit to the heating or HVAC actuator according to the system wiring diagram provided by the installer or equipment manufacturer, ensuring power is disconnected before making connections.
