## Long description

The TECH ST-293z v3 wired room thermostat is a flush-mounted, two-position (on/off) temperature controller in a white glass design, powered by 230V. Intended for regulation of room temperature in heating or cooling circuits, the thermostat provides straightforward on/off control via a clean glass front and compact body that fits standard wall boxes. The device is suitable for use in residential and light commercial interiors where simple temperature regulation and unobtrusive appearance are required.
Advantages
The thermostat combines a minimalist glass finish with a standard two-position relay control, offering reliable switching of heating or cooling equipment at mains voltage. Installation in a flush-mounted wall box ensures a discreet profile, while the glass front is easy to clean and integrates well with modern interiors. Designed for clear on/off operation, the unit reduces setup complexity compared with modulating controllers.
Suitable for
Room temperature control for radiators and boiler systems that use on/off switching
Control of electric heaters or convectors operating at mains voltage (230V)
Simple cooling circuit control where two-position switching is acceptable
Residential rooms, apartments, offices, hotel rooms, and small commercial spaces
Key specifications
Mounting type: flush-mounted, compatible with standard wall boxes
Control type: two-position (on/off) thermostat
Supply voltage: 230 V AC
Front material: glass, white finish
User interface: single control element for setting temperature (mechanical or simple electronic dial/button)
Application: room-level temperature regulation for heating or cooling circuits
How to use
Install the thermostat into a suitable flush-mounted wall box following local electrical regulations and ensuring power is disconnected during wiring. Wire the line and load conductors to the designated terminals and secure the device to the box; restore power and set the desired temperature using the control on the glass front. When the ambient temperature falls below the setpoint, the thermostat closes the internal relay to activate heating; when the temperature rises above the setpoint, the relay opens to stop heating or enable cooling circuits depending on installation.
Usage recommendations
Mount the thermostat on an interior wall at a representative height (typically about 1.5 m) away from direct sunlight, drafts, or heat sources to ensure accurate ambient temperature measurement. Use the unit for systems designed for two-position control and verify compatibility with the connected heating or cooling equipment and mains voltage before installation.
