TECH R-8B is a room wireless two-state thermostat in white designed to provide simple and reliable control of heating systems via a binary (on/off) output. Intended for use as a standalone room temperature controller, the device communicates wirelessly and is compatible with the L-8 unit. The thermostat offers a compact wall-mounted design suitable for domestic and light commercial environments where basic temperature regulation and straightforward replacement of an existing thermostat are required.

Advantages

The thermostat delivers on/off control with a clear user interface and a neutral white housing that integrates into typical interiors. Wireless compatibility with the L-8 unit removes the need for complex wiring and allows flexible placement in rooms. The two-state operation simplifies installation and programming, and the device is designed for stable temperature regulation in heating systems that accept a binary control signal.

Suitable for

• Domestic central heating and radiators that use on/off control
• Light commercial premises requiring basic room temperature control
• Upgrading or replacing simple non-programmable thermostats
• Integration with compatible wireless heating controllers such as the L-8 unit

How to use

Mount the thermostat on an interior wall away from direct sunlight, drafts and heat sources to ensure accurate temperature sensing. Pair the device with the L-8 unit following the manufacturer's pairing procedure, then set the desired room temperature. The thermostat will switch the heating system on or off according to the measured room temperature and the two-state control logic. For replacement of an existing thermostat, remove the old device, install the R-8B in the same location, and complete the wireless pairing and testing steps.

Usage recommendations

Position the thermostat at eye level in a representative location for best temperature reading; avoid placing it near windows, doors, or heat-emitting appliances. Periodically verify wireless connection to the L-8 unit and test on/off response after installation or maintenance to ensure correct operation.
