Vaillant ecoTEC Boiler Timer Switch Replacement

If you’re looking for a replacement timer for your Vaillant ecoTEC Boiler, be it due to a fault or other reason with the one currently in use, the Vaillant 0020116882 24 hour timeswitch 150 is a model known to compatible with practically all Vaillant ecoTEC models made from 2012 to the present time. With minimal controls and the classic analogue mechanical dial timer ring, the 150 is extremely simple to use. And the swap over in most cases is a quick and easy installation.

The time increments on the 150 are set in blocks of 15 minute intervals. This gives the user a lot of control and precision. So much so that it allows for up to a massive 48 heating on/off times. The 150 Timeswitch has 4 pins. If your boiler has 5 pins it does not necessarily mean it will not be compatible. Many people have reported it works just fine when replacing their present timer, which was 5 pin.

Also works with some Home and Pro models of Vaillant boilers, such as the 24 / 28 and some Vaillant models made before 2012. But do check compatibility details thoroughly before purchase, as it doesn’t work with all models.
