## Description

Product Description electronic 7 Legal Disclaimer 60.00

Review: Simple and easy to program. Precise time, ideal for Economy 7 or standard. - Cant quite believe how fantastic this product is. After looking at many different models I finally made my decision based on the review of desertcart1 who had attached photos and I was astounded my old timer was the same as their old timer. So I had no doubt it would fit perfectly. It looks like it might be tricky to program but it is so easy and takes seconds. Infact it is so much quicker and more efficient than trying to set the old mechanical style timer. It is extremely precise as you can program it to the exact minute as oppose to roughly guessing on an old dial style timer. A very simple efficient design and from what I have read the Horstmann series seem to be pretty much all interchangeable. The other great feature my old one didn't have is its ability to automatically switch between summer time and winter time. You must have it set to this feature if you need it. I do as I have Economy 7 but it depends on ones own system. As it has a battery back up the clock did not need setting and was telling the correct time as soon as it was given power. The boost button will heat your water for one hour before switching off should you need it. So easy to use I wouldn't consider anything else. Comes with full installation and user guides.
Review: Easy to install - I bought this after my old timer packed in. I read some reviews and decided that I would try this. I fitted it on my own - very easy to install - so there was no need to pay for an electrician. It was working within 30 minutes from start of install to the finish. The timer function is easy to operate and I like that it has summer and winter settings too. Would definitely recommend.

## Questions & Answers

**Q: is it simple plug in to quartz wall box**
A: Mine was replacing a mechanical Newlec timer which I believe is an older version of the Horstmann Quartz: for the Newlec the colour codes are identical, just unplug the old timer connectors and plug in the new ones. http://www.horstmann.co.uk/water-heating.php is your friend here - the installation guides for the Quartz and the Electronic 7 are on there and show identical pin-outs. Disclaimer: I am not an electrician: you should exercise due diligence before proceding!

**Q: Can this item replace an old 'horstmann e7 bx' unit?**
A: I used it as a direct replacement for an existing 30 year old Horstmann E7 unit but I can’t say whether it was a ‘bx’ unit.

**Q: Does anyone know if this unit will replace an old Electra tech control panel? I only need to use it for setting the hot water not radiators**
A: I don't know if it will replace 'an old Electra tech control panel' but you can certainly set this unit for water heating only for any chosen time period/duration with summer/winter auto time change.There is also a Boost selector for use at anytime outside your 'set' period. Hope it helps!!

**Q: Can i replace my old horstmann electronic 7 with this**
A: You can replace an old Horstmann electronic 7 with the new model. It fits directly into the existing backplate fittings.

### ⭐⭐⭐⭐⭐ Easy to install

### ⭐⭐⭐⭐⭐ Great and easy replacement for Analog unit
*by K***G on 19 July 2022*

I bought this to replace the old analog Horstmann unit I had fitted to my immersion tank which had a minimum time setting of 4.5 hours. This new digital control unit is great, allows me to set the time intervals easily which will save me a lot of money as I can heat the tank for only a couple hours a night, as opposed to the minimum 4.5 hour minimum on the analog unit. Fitting took less than 5 minutes. Plug and play after removing the base plate, all the connections are easily labelled and the existing mounting plate didn’t need to be change. £70 is quite steep for what this is, but there’s no easy alternatives.
