## Long description

The TECH F-12B wired room thermostat is a wall-mounted temperature controller designed for installation on L-X and L-12 rails and compatible with standard 55 mm frame systems. Finished in white, the device offers a wired connection for HVAC or heating circuits and is intended for indoor climate regulation in residential and light commercial settings where a rail-mounted, fixed installation is required. The form factor and mounting method make it suitable for integration with modular electrical frames and existing rail infrastructure.
Advantages

How to use
Install the TECH F-12B thermostat onto the appropriate L-X or L-12 rail according to the mounting instructions and secure it within a compatible 55 mm frame. Connect the device wiring to the heating or HVAC control circuit following the system wiring diagram and safety rules.
