## Long description

TECH ST-297V3 is a two-state (on/off) flush-mounted room thermostat with a 3 mm glass front in white finish. It provides straightforward temperature control for heating or cooling systems via a single switching output and is designed to fit standard recessed wall boxes. The compact, flat glass front and white frame make it suitable for residential and light commercial interiors where a simple, reliable thermostat is required.
Advantages
The thermostat offers clear on/off actuation for easy integration with valves, relays or simple actuators. Its 3 mm glass front ensures a smooth, easy-to-clean surface that resists scratches and maintains a consistent appearance. Flush mounting provides a low-profile installation that aligns with standard electrical boxes, reducing visual clutter on the wall. The unit’s basic two-state operation simplifies wiring and configuration compared with multi-stage or programmable controllers.
Suitable for
Basic room temperature control in apartments and houses
Small offices and light commercial spaces requiring simple on/off control
Control of heating systems such as boilers, electric heaters or radiator actuators
Simple cooling or ventilation circuits with on/off actuators
Key specifications
Control type: two-state (on/off) switching output
Mounting: flush-mounted for standard recessed wall boxes
Front material: 3 mm tempered glass, white finish
Frame colour: white
Operating environment: indoor use, residential and light commercial
How to use
Install the thermostat in a standard recessed wall box at an appropriate height (typically 1.2–1.5 m above floor level) away from direct sunlight, drafts and heat sources to ensure accurate ambient temperature measurement. Connect the switching output to the heating or cooling actuator following the wiring diagram supplied with the unit and local electrical regulations. After powering the device, set the desired switching point using the control on the unit. The thermostat will switch the connected actuator on or off when the room temperature crosses the setpoint.
Usage recommendations
For reliable operation, place the thermostat on an interior wall away from windows, doors and ventilation outlets. Use compatible on/off actuators or relays sized appropriately for the controlled load and install according to applicable electrical safety standards. Periodically clean the glass surface with a soft, damp cloth; avoid abrasive cleaners and excessive moisture.
