Product information

Description

TECH ST-293v3 black is a flush-mounted room controller with a glass front designed for two-state (on/off) operation. Intended for simple control of heating or ventilation circuits that accept binary commands, the unit installs under plaster for a discreet appearance. The device provides a clear touch interface suitable for residential and light-commercial interiors where straightforward switching of loads or calling preset HVAC setpoints is required.

Advantages

The controller combines a sleek black glass front with a compact flush-mounted design that minimizes visual impact on interior décor. Two-state operation ensures compatible and reliable switching of binary-controlled actuators, relays or contactors. The glass surface supports intuitive touch or press interaction and is easy to clean, while flush mounting offers protection and a low-profile finish. The unit is engineered for straightforward integration into standard wall-box installations and for consistent performance in typical indoor environments.

How to use

Install the controller into a compatible in-wall box and connect to the controlled circuit following applicable electrical codes and wiring diagrams.
