## Long description

TECH ST-294V2 Black is a room wireless two-state (on/off) thermostat designed to maintain target temperature by switching heating circuits or electric heaters between two states. The compact black device measures ambient room temperature and transmits control signals to compatible wireless receivers, enabling simple on/off regulation suitable for residential and commercial indoor spaces. The thermostat focuses on straightforward temperature control without complex modulation, providing a reliable means to manage heating equipment through wireless pairings.
Advantages
The thermostat provides wireless operation for flexible placement and easy installation where running control wiring is impractical. Its two-state output ensures predictable on/off switching behavior that is compatible with standard electric heaters, boiler zone valves, or relay-based controllers. The black housing offers a neutral, modern appearance that fits typical interiors, while the device’s basic control logic simplifies setup and operation for users and installers.
Suitable for
Controlling electric panel heaters or convectors in single rooms
Managing heating circuits via wireless receivers in residential apartments
Temperature control of office or commercial spaces with on/off heating systems
Integration with relay-based boiler zone controls that accept simple on/off commands
Key specifications
Operating mode: two-state (on/off) thermostat
Mounting: wall-mounted room thermostat design for indoor use
Control method: wireless transmission to compatible receivers
Color: black finish suitable for modern interiors
Intended application: control of heating circuits and electric heaters
How to use
Mount the thermostat on an interior wall away from direct sunlight, drafts and heat sources to ensure accurate ambient temperature measurement. Pair the device with a compatible wireless receiver according to the receiver’s pairing procedure, then set the desired target temperature. The thermostat will switch its output to the paired receiver when the measured room temperature crosses the setpoint to perform on/off control of the connected heating equipment.
Usage recommendations
Place the thermostat at typical room height (about 1.2–1.5 m) on an interior wall and avoid locations near windows, doors, radiators or kitchen heat sources. Use with receivers and heating equipment that support on/off control and comply with local electrical installation rules; consult a qualified installer for wiring and compatibility verification.
