VEMER - VN170700 - KEO-B electronic flush-mounted thermostat with battery operation

The VEMER KEO-B (code VN170700) is an electronic flush-mounted thermostat with battery operation, designed to regulate the temperature of heating or cooling systems in residential and commercial rooms. It is characterised by its extreme ease of use.

Design and controls

• Front knob to set the desired temperature
• Selector switch for operating mode: cooling, off or heating
• White and anthracite grey frames and front panels included
• Optional silver "Fr.Keo-B" front panel available separately

Configurable digital input

The digital input allows the connection of an external temperature probe X.Temp (code VN883500) or a device that can reduce the setpoint by 3 °C.

Setpoint limitation

The patented setpoint limiting system is useful for installations in public places, preventing unauthorised people from changing the temperature.
