Keo-A LCD

VE558300

Flush-mounting thermostat with LCD display and 230 V AC power supply. The Keo-A LCD device is characterized by its ease of use. Vemer also provides Keo-B LCD with battery power supply. 

What is a thermostat 
A thermostat is a device designed to regulate the temperature of a heating or cooling system in a specific room. It works by sensing the current room temperature and, based on the temperature set by the user, turns the heating or air conditioning system on or off. 

Design of the thermostat
The device features two small physical buttons and a display with blue backlighting, providing the product with elegance and sobriety. In case you do not need the display and prefer to set the temperature via a handy knob, Vemer also provides Keo-A

Mounting tips and compatibility
It is possible to adapt the thermostat to the cover frames of the main switch and socket systems, thanks to:

  • white frames and faceplates included in the package
  • silver-colored “Fr.Keo-A LCD” faceplate, which can be purchased separately 

Keypad lock 
The “keypad lock” function with password, useful, for example, for installations in public places, prevents unauthorized people from changing settings
