VEMER - VE757800 - Olympo LCD Nero electronic thermostat
The VEMER Olympo LCD Nero is a wall-mounted electronic thermostat designed to regulate the temperature of heating or cooling systems in a specific room. It combines elegant aesthetics with practical functionality, making it suitable for both residential and commercial installations.
The device features a convenient rotary knob for easily setting the desired temperature, and a selector to choose between heating (winter) and cooling (summer) operating modes. The LCD display shows the measured room temperature alongside the setpoint value.
