VEMER - VE757500 - Olympo 230 Bianco electronic thermostat, wall-mounted, 230 Vac, knob control, setpoint limitation
The VEMER Olympo 230 Bianco (VE757500) is a wall-mounted electronic thermostat powered at 230 Vac, designed to regulate the temperature of heating or cooling systems in residential and public environments. Its essential design combines simplicity and practicality for everyday use.
Intuitive Control
The device features a convenient knob for easily setting the desired temperature, along with a dedicated selector to switch between operating modes — Summer (cooling) and Winter (heating). The setting range covers 5 to 35 °C with a fixed 0.3 °C differential and ON-OFF or proportional regulation.
Patented Setpoint Limitation
A patented setpoint limiting system prevents unauthorised users from modifying the temperature, making the Olympo 230 Bianco an ideal solution for installations in public places, offices and shared spaces.
