Chances are you have one in your toolkit or in the van. Now you can keep one in your phone for instant use!

We’re talking of course about the famous Horstmann Heating Programmer Replacement and Wiring Guide which is now available in APP format.

If you’re replacing or upgrading a central heating programmer why just fit what wasthere before when you could go one better and fit a modern Horstmann product with extra features and benefits for the customer?

• This user friendly APP gives you a range of invaluable information at your fingertips - time switches and programmers - they are all there.

• From straight forward electro-mechanical to an electronic 2 channel 7 day
programmer - when replacing or upgrading make a perfect match.

• Many Horstmann units are simple ‘plug in and replace’ - no rewiring.

• A simple 3 step selection process provides all the information you need - which replacement is recommended ... terminal positions in relation to the current back plate ... makes life easier when re-wiring is necessary.

Whichever Horstmann unit you select, you can be sure that its well designed, beautifully engineered, fully guaranteed and bang up to date with the latest spec. You won’t be replacing it in a hurry.

This APP is an invaluable tool for all professional installers working in the domestic heating field in the UK. We think you’ll agree.

Great app

I bought a house with an old tick tock timer central heating/hot water controller in the bedroom that was driving me crazy.
This app saved me having to get an electrician and meant I knew which model to order without having to do any rewiring.
Thanks - much appreciated (and no, I don't work for Horstmann!)
