Horstmann H27XL Programmer, Multi

Product Information

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. I imagine the battery is there to keep the timer settings in the event of the power cut, but once the battery is done, that's it - the H27XL is dead. The HORSTMANN (SECURE) CHANNELPLUS H27XL PROGRAMMER - Now Use 4210051 is a genuine, brand new Horstmann Controls product, covered by a Horstmann Controls manufacturer's guarantee. 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.

I got this as a replacement for an identical controller, due to the battery having run out on the previous unit. So, like others, at Horstmann we have addressed perceived shortcomings of older controls by introducing larger, more easily read screen displays, presenting . 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. 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.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. 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. 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. As a local supplier, PHC are proud to support Horstmann by distributing the entire range of Horstmann products.

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. Second generation programmers that offer up to 4 independent channels and feature improved display and easier programming.
