What can I use this timer with?
Set your immersion heating to come on when you want it to, and save time and power in the process. This timer can be used to control your heating and other hard wired appliances up to 13A. Choose when the heating comes on with a 24-hour control surface that can be set in 15 minute intervals. With the convenient LED power indicator, you can see at a glance whether the heating is on. Helpfully, the override function lets you switch the heating on any time you need, whether it is set to start or not.

Rated 1 out of 5 by from Terrible instructions Bought this product just before Christmas' wired it up with difficulty as fixing screws get in the way. No matter how many times we tried to get the clock to work, even going on line and watching various instruction videos, no way could we get it to work. I realise it is cheap, but not if it doesn't do the job!

Rated 1 out of 5 by from Doesn't work I bought ths timer today to replace my existing one where the clock function has stopped working. Got a friend to fit it only to find, guess what? the clock function doesn't work! It was the only one in stock so makes me suspicious it might have been returned previously as non working
