Room wireless thermostat TECH ST293V2 two-state controller with glass front panel, white

Room wireless thermostat TECH ST293V2 is a two-state on/off controller designed for basic temperature regulation in residential and commercial interiors. Featuring a white glass front panel and a compact wall-mounted form factor, this thermostat provides straightforward control of heating or cooling equipment through wireless communication with a compatible relay or receiver. The unit is intended for applications where simple, reliable switching between active and inactive states is required.

Advantages

The glass front panel offers easy cleaning and a modern appearance while the two-state control logic simplifies installation and operation. Wireless connectivity removes the need for extensive wiring and enables flexible placement on interior walls. The thermostat’s clear temperature setpoint interface and stable on/off switching reduce overshoot and cycling when paired with appropriate actuators and system settings.

Suitable for

• Basic temperature control of domestic or small commercial boilers
• On/off control of electric convectors and portable heaters
• Temperature zoning in simple HVAC setups with wireless relays
• Replacement of analog or wired thermostats where wireless operation is preferred

Key specifications

• Control type: two-state (on/off) thermostat
• User interface: glass front panel, white finish
• Mounting: wall-mounted room thermostat
• Suitable loads: boilers, electric heaters, HVAC actuators via relay/receiver
• Operation: wireless communication to compatible receiver/relay
• Setpoint adjustment: manual temperature setpoint selection

How to use

Mount the thermostat on an interior wall away from direct sunlight, drafts and heat sources for accurate ambient measurement. Pair the thermostat with the compatible wireless receiver or relay according to the manufacturer's pairing procedure, then configure the receiver to switch the heating or cooling device in response to the thermostat’s on/off signals. Set the desired temperature setpoint using the front control interface; the thermostat will switch the controlled device on when the room temperature falls below the setpoint and off when it rises above it.

Usage recommendations

For stable temperature control, place the thermostat at typical room occupancy height and avoid mounting near doors, windows or heat-emitting appliances. Use with an appropriate relay or receiver rated for the connected load and follow electrical safety standards during installation. For zoned systems, combine multiple thermostats with dedicated wireless receivers to achieve independent control across areas.
