Government regulations on the installation of heating controls as detailed in Part L of the new Building Regulations, the Horstmann Controls ChannelPlus H37 XL electronic programmer provides a fully compliant solution. 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.

Established in 1854 as a manufacturer of clocks, today Horstmann are a leading manufacturer of heating and hot water controls based in Bristol. In addition to controlling a heating system, the timeswitch can be used for the timed control of a security lighting system due to its 3-amp contacts.This product has now been replaced by the: Horstmann (Secure) 2 Channel Receiver Smart Programmable Thermostat (C1727). One thing to watch is if you turn off the mains electric switch on the wall, say over the summer, the controller's battery is used more keeping its time setting, and eventually shortens the life of the battery.

Compatible with Horstmann ChannelPlus H27XL series: Ensures perfect integration with your existing heating system. due to a plumbing issue we now have to wire a second boiler alongside another in a reasonable size house. The programmer, otherwise known as the timeclock, timer or clock is a device that enables you to control when the hot water and heating is switched on to maximise home comfort. Every time there was a power cut, the battery no longer held the times I had set so I had to manually re-set them, a tedious process.

The ChannelPlus H27XL is ideal for controlling either the central heating or hot water in a heating system. 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.

As a local supplier, PHC are proud to support Horstmann by distributing the entire range of Horstmann products. I’m not sure which controllers will be compatible with my system so any advice would be greatly appreciated.Hi I have a Horstmann channel plus XL ModelH27 that has failed, will this model be a direct replacement and not need any electrical alterations to the back plate.

You can have these times different for each day, or can have them the same each day, which is a bit easier and takes less time to set up. Delivered as a direct replacement for a failed unit that had done marathon service, on fitting it was discovered one of the little clips for the front was broken and the unit doesn't light up when you press a button making programming difficult. We are unable to deliver to the Isle of Scilly, Jersey, Guernsey, Northern Ireland, Isle of Man and the rest of Europe. The single, two and four channel versions are voltage free as standard and use the same backplate as Horstmann's 425 and 5 Series programmers.As it was a like-for-like replacement, you only need to replace the front part which contains all the electronics, which simply slots into where the original detached. Takes a bit of navigation through the menus but very easy to program once you get used to what the buttons do.
