## Long description

Wired dual-state room thermostat ST-297z v3 Tech Controllers — Flush-Mounted, Black is a compact, wall-recessed temperature control device designed for simple room-level heating regulation. The thermostat operates as a two-state (on/off) controller with a binary output for direct switching of heating equipment or interfacing with relay modules. Its flush-mounted design and black finish are intended for concealed installation in standard wall boxes, providing discrete control in residential and light-commercial interiors.
Advantages
The thermostat offers straightforward operation and a clear setpoint interface for reliable temperature control without complex configuration. Its wired connection provides stable communication and power, avoiding wireless interference or battery replacement. The flush-mounted form factor reduces protrusion from the wall for a neat appearance, while the black color integrates with modern interior finishes. The two-state output simplifies integration with boilers, electric heaters or actuator relays for on/off control.
Suitable for
Residential room heating control where simple on/off regulation is required
Light-commercial spaces such as offices or small retail units with centralized boilers or electric heating
Installations that require flush-mounted, low-profile thermostat devices
Systems using relay modules or actuators for binary heating control
Key specifications
Control mode: two-state (on/off) room thermostat
Mounting type: flush-mounted for standard in-wall installation
Finish and color: black front plate
Output: binary switching output suitable for direct relay or actuator control
Application: room-level temperature regulation for residential and light-commercial environments
How to use
Install the thermostat into a compatible recessed wall box and connect the wiring to the heating control circuit according to local electrical standards and the device wiring diagram. Set the desired temperature setpoint using the thermostat controls; the device will switch its binary output to activate or deactivate the connected heating equipment when the measured room temperature crosses the setpoint. Ensure installation and wiring are performed by a qualified electrician or technician familiar with heating system controls.
Usage recommendations
Locate the thermostat on an interior wall away from direct sunlight, drafts, or heat sources to ensure accurate room temperature measurement. Use compatible relays or actuator modules when controlling high-power heating loads. Regularly verify wiring connections and setpoints during commissioning to confirm correct on/off switching behaviour.
