Room wireless two‑stage battery thermostat TECH T-3.2 (surface mount), white

Wireless room thermostat TECH T-3.2 (surface mount) is a battery-powered, two-stage temperature control device designed for simple on/off regulation of heating or cooling equipment. Its compact white housing and surface-mount design allow installation on interior walls without recessed wiring. The thermostat communicates wirelessly with compatible receivers and provides reliable basic temperature control for residential and light commercial spaces where straightforward, low-maintenance regulation is required.

Advantages

The TECH T-3.2 offers two separate output stages that enable independent control of two circuits or staged control of a single system, reducing installation complexity compared with multi-wire thermostats. Battery power removes the need for mains wiring at the mounting point, simplifying retrofits. The surface-mount enclosure provides a neat appearance on standard interior walls while allowing easy access for battery replacement. Wireless operation reduces cable runs and supports flexible placement in rooms where sensor accuracy matters.

Suitable for

• Basic on/off control of single-stage or two-stage heating systems
• Control of electric heaters, boiler zones with relay receivers, or simple cooling equipment
• Retrofit applications in apartments, houses, offices, and light commercial spaces
• Locations where cable routing is difficult or surface mounting is preferred

Key specifications

• Power supply: battery-operated (replaceable batteries)
• Control type: two-stage on/off outputs
• Mounting: surface mount for interior walls
• Housing color: white; compact form factor suitable for standard rooms
• Communication: wireless connection to compatible receivers
• Application environment: indoor use for residential and light commercial spaces

How to use

Mount the thermostat on a vertical interior wall away from direct sunlight, draft sources, or heat-producing appliances to ensure accurate temperature sensing. Install batteries according to the polarity indications and pair the thermostat with a compatible receiver following the manufacturer pairing procedure. Set the desired temperature and configure the two-stage outputs according to the heating or cooling strategy—either controlling two separate circuits or staging a single system. Replace batteries as needed and perform periodic checks to confirm wireless connectivity and correct operation of the controlled equipment.

Usage recommendations

For reliable temperature measurement, position the thermostat at typical room height (about 1.2–1.5 m above the floor) and avoid mounting near windows, doors, or heat sources. Use compatible wireless receivers rated for the connected equipment and follow local electrical safety standards during installation and wiring of receivers. Regularly check battery level and replace batteries before low-power operation affects control performance.
