## Long description

The TECH ST-293z v3 wired room thermostat in black is a two-state (on/off) wall-mounted temperature controller designed for 230V heating systems. With a glass front and flush-mounted design, the device provides a compact and discreet installation for indoor residential and commercial spaces. The thermostat operates by switching the heating load at the configured setpoint to maintain a stable room temperature and is intended for straightforward, reliable temperature control where basic on/off regulation is sufficient.
Advantages
The thermostat offers a clear glass front and a minimalist appearance that integrates into modern interiors. Its two-state switching mechanism is compatible with standard 230V heating circuits and provides simple, deterministic control without complex configuration. Flush-mounted construction ensures a neat installation flush with the wall surface, while solid mechanical components provide long-term reliability for basic heating applications.
Suitable for
Residential rooms such as living rooms, bedrooms and hallways
Small commercial spaces like offices, shops and waiting areas
Simple heating systems that require on/off temperature control
Retrofit projects where wall-mounted, flush installation is preferred
Key specifications
Control type: two-state (on/off) temperature control
Supply voltage: 230 V AC
Mounting: flush wall-mounted design
Front panel: glass finish in black
Intended use: indoor ambient temperature regulation for heating systems
How to use
Install the thermostat into a standard flush wall box and connect it to the 230V heating circuit following local electrical regulations and wiring diagrams. After mounting, set the desired temperature setpoint using the thermostat’s control interface. The device will switch the connected heating load on when room temperature falls below the setpoint and switch it off when the setpoint is reached. Regularly verify wiring and mechanical fastening during installation and after any maintenance.
Usage recommendations
Place the thermostat on an interior wall away from direct sunlight, drafts, or heat sources to ensure accurate temperature sensing. For safety and compliance, have a qualified electrician perform the electrical connection and follow local codes. Use the device for basic on/off heating control; if modulating or programmable control is required, consider a different thermostat model designed for that functionality.
