We inherited an older one of the same model which I found very difficult to use: the buttons took a very long time to react, and every time there was a tiny power cut or surge the device would lose the programming which had taken me ages to enter. Eventually I realised that the internal battery, which is non-replaceable, must be dead, because it was supposed to be able to keep its programming during power cuts. To replace it with the new programmer was simple as the existing backplate with the wiring simply plugs into the back of the new one. It is a very strong fit, so you need to apply a fair amount of leverage to get the old one off and need to press the new one on firmly until it has fully engaged. Like most multi function devices these days the ability to write clear unambiguous instruction booklets lags some way behind the intelligence of the device itself, so it takes a bit of trial and error to become familiar with it. Fortunately as I was no longer struggling with worn-out buttons and a dead internal battery, putting in the settings I wanted was much quicker than with the old device. Hopefully, since the device should no longer keep losing its settings I won't have to set the timings again for quite a while. Review: Does the job well - Bought this to replace an earlier version which only had a 7 day setting (same setting each day). The new one lets you set every day of the week different, which is what I wanted. So easy to fit as well, Old one unplugged, new one plugged straight in. Up and running in 10 mins! Worth the cost and I sold the old one on 'you know where'! ## Features - 1, 2, 3 or 4 channels - 24 hour or 7 day - Back-lit LCD display - Preset clock - Automatic Winter/Summer time changes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002LYPFH6 | | Best Sellers Rank | 1,104,306 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,579 in Thermostats | | Brand | Horstmann | | Colour | Multi | | Customer Reviews | 4.7 out of 5 stars 190 Reviews | | Display Type | LCD | | Display type | LCD | | Global Trade Identification Number | 05015914355011 | | Included Components | no_components | | Item Type Name | Programmer | | Item Weight | 410 Grams | | Item weight | 410 Grams | | Manufacturer | Horstmann | | Manufacturer Part Number | H27XL | | Model Number | H27XL | | Product Warranty | 1 year. | | Unit Count | 1.0 count | | Unit count | 1.0 count | | Voltage | 24 Volts | ## Product Details - **Colour:** Multi - **Brand:** Horstmann - **Voltage:** 24 Volts - **Item weight:** 410 Grams - **Display type:** LCD ## Images ![Horstmann H27XL Programmer, Multi - Image 1](https://m.media-amazon.com/images/I/51g79koY3cL.jpg) ![Horstmann H27XL Programmer, Multi - Image 2](https://m.media-amazon.com/images/I/31KE8VlW4nL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to replace previous similar models *by M***K on 1 July 2020* Very easy to use to replace previous similar models.
