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.due to a plumbing issue we now have to wire a second boiler alongside another in a reasonable size house. 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. In this age of advanced electronics and the growing trend towards RF technology, Horstmann still sells them in thousands and remains confident they have a place – albeit possible a niche – alongside their . Our previous model with exactly the same programming procedure the heating setting was the key control.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. do I have to use all these terminals and if so how do I connect the respective ones to the cylinder stat and the room stat in the wiring centre. We are unable to deliver to the Isle of Scilly, Jersey, Guernsey, Northern Ireland, Isle of Man and the rest of Europe. 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.

The ChannelPlus H27XL timeswitch has a boost function for 1 or 2 hour boosts as well as an advance button to move onto the next stage in the programme. Just be aware that the contacts between the backplate and the programmer are very tight as supplied and it takes a forceful tug to get the unit off again once fitted (which is what stumped the builders! The ChannelPlus H27XL is ideal for controlling either the central heating or hot water in a heating system. But after speaking to Horstmann because there was no wiring diagram in the box they informed I needed to use all the terminals.

Throughout the years Horstmann have pioneered many innovative products for central heating and hot water control, including the UK’s first purpose designed central heating programmers (Potterton 411), the first time clock with a standardised, universally interchangeable back plate, and the UK’s first three channel programmer, followed later by a four channel programmer.

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. I need to replace a Horstmann Channel Plus H21XL 2 Channel Programmer, but I believe they are now discontinued.

So, like others, at Horstmann we have addressed perceived shortcomings of older controls by introducing larger, more easily read screen displays, presenting . 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. Part of a range of electronic programmers that offer up to four independent channels and feature a large, easy to read display and simple menu-driven programming. 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. Compatible with Horstmann ChannelPlus H27XL series: Ensures perfect integration with your existing heating system.

Second generation programmers that offer up to 4 independent channels and feature improved display and easier programming. Among the best known Horstmann products is the 425 range of electro-mechanical time clocks, with models including the Coronet time switch, and Tiara and Diadem twin channel programmers.
