Vaillant have been setting standards within the heating market for more than 140 years.  They are passionate in developing systems which utilise sustainable energy sources to enable their customers to enjoy simple, healthy and energy saving solutions for your heating and hot water requirements.

The VRT350F can be programmed to three independent time settings each day. These can be altered manually and set in advance, making the VRT350F one of the most flexible thermostats on the market today.


  • Wireless control
  • Fits into the fascia of Vaillant ecoTEC boilers from 2012 to present (extra controls required for System & Open Vent boilers)
  • 3 independent time settings per day
  • Blue backlit display
  • 2 push buttons & 1 rotary knob
  • Holiday set-back function
  • Calendar function
  • Automatic summer/winter change over
  • Advanced override setting 

The VRT350F also monitors the room temperature and actively adapts boiler output to match the temperature set, helping you to optimise your heating's performance.

With its fully backlit blue screen and plain black text, the VRT350F allows you to get a clear understanding of the information presented, allowing you to get your central heating working exactly the way you want it to. Programming your thermostat is simple too, thanks to the easy-to-use rotary knob and two push button interface.

The holiday set-back function not only allows you to turn your heating off while you are away but you can also set it so that it is nice and warm for when you return.  In addition to this there is also a calendar function with support for automatic summer/winter changeover - so you shouldn't get caught out when the clock goes back or forward.


The great thing about the VRT350F is that is works with all Vaillant EcoTEC boilers from 2012 to present.

Receiver pins may need removal prior to installation, depending on the age of your boiler. Watch our video to see how this works. 


Additional controls and wiring may be required to use the VRT350F with System & Open Vented boilers. 

For more information we advise that you refer to the installation manual at the bottom of this page or consult a heating engineer.
