Horstmann H27XL Programmer, Multi

Product Information

due to a plumbing issue we now have to wire a second boiler alongside another in a reasonable size house. 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 . li>Compatible with Horstmann ChannelPlus H27XL series: Ensures perfect integration with your existing heating system. The 4 channel programmer follows Horstmann Controls’ AS (or Advanced Simplicity) design parameters which features an easily read, bright blue back lit LCD display .

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.

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.

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. Advance and override functions: Easily adjust your heating without affecting the programmed settings. The C1727 also includes many of the latest Boiler Plus energy-saving features such as optimum start and stop per heating zone, as well as on-off load compensation.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. The ChannelPlus H27XL is ideal for controlling either the central heating or hot water in a heating system.

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. I’m not sure which controllers will be compatible with my system so any advice would be greatly appreciated.Once the unit is put together it is extremely difficult to prise apart, so don't clip together until in its final place on the wall and the wiring has been completed, it is possible to part clip it in place to check everything is working prior to final installation, but overall very pleased with my purchase, good instructions with alternative wiring for replacing your present unit. 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. A suitable replacement is: Horstmann (Secure) 2 Channel Receiver Smart Programmable Thermostat (C1727). 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. Takes a bit of navigation through the menus but very easy to program once you get used to what the buttons do.

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. 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. As a local supplier, PHC are proud to support Horstmann by distributing the entire range of Horstmann products. This means you don't have to disconnect and reconnect any of the wires coming into the back part, which is really only a terminal board.
