Vaillant TimeSWITCH 150 Plug In 24 Hour Analogue Timer

The Vaillant TimeSWITCH 150 Plug In 24 Hour Analogue Timer is a simple mechanical clock that plugs straight into the fascia of a Vaillant ecoTEC combi boiler. There is no wiring to run, so it is a quick way to add basic time control to the heating.

What the timeSWITCH 150 does

It is a single channel, 24 hour timer. You push in the segments round the dial for the times you want the heating on, and the same pattern repeats every day. An override switch lets you run the heating outside those times, or keep it off, without resetting the dial. For many homes that is all the control they need, and the dial is easy for anyone to read.

Common Questions

How do I install the Vaillant timeSWITCH 150? It plugs onto the connector in the control panel of a Vaillant ecoTEC combi boiler. Fitting means opening the boiler’s electrical box, so isolate the supply first and have a qualified installer do it.

Does the timeSWITCH 150 need wiring to connect it to the boiler? No, it takes its 24V supply straight from the boiler, so there’s no cable to run back to a wall. It’s made to suit Vaillant ecoTEC combi boilers.

How do I use the Vaillant timeSWITCH 150? Turn the dial to the right time of day, then push in the slides for the times you want the boiler on and leave the rest out. The switch lets you choose timed, permanently on or permanently off.

What happens to the timeSWITCH 150 in a power cut? There’s no battery backup, so the clock stops and you’ll need to turn the dial back to the right time. Your on and off slides stay just as you set them.

Do I still need a room thermostat with the timeSWITCH 150? Yes, because it only switches on time and doesn’t sense how warm the room is. Pair it with a room stat such as the Vaillant VRT 50 so the house doesn’t overheat.

Can I use the timeSWITCH 150 with a frost thermostat? Vaillant advise against fitting it with a separate external frost stat, as the ecoTEC boiler has its own frost protection built in.

Fitting and setting up, with help in Glasgow

Isolate the boiler electrics before you remove the blanking plate from the fascia. Plug the timer in as the boiler manual shows, refit the cover and switch back on. Set the time of day by turning the dial, then push the segments for your heating periods. If the property needs separate weekday and weekend times, look at the 7 day digital programmer instead.
