About this deal

li>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. 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. The wireless CentaurPlus C17 ZW operates with the latest Horstmann HRT4-ZW wireless room thermostat and together, the two offer a highly efficient controls package ideally suited to combi boiler installations. Hopefully, since the device should no longer keep losing its settings I won't have to set the timings again for quite a while.

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. XL Series 2 Electronic Programmers 17 CHANNELPLUS H47XL CHANNELPLUS H37XL CHANNELPLUS H37VXL CHANNELPLUS H27ZXL CHANNELPLUS H27XL CHANNELPLUS H21XL CHANNELPLUS H17XL CHANNELPLUS H11XL Programmer with 7 day setting over four independent channels. The ChannelPlus H27XL is ideal for controlling either the central heating or hot water in a heating system. I got this as a replacement for an identical controller, due to the battery having run out on the previous unit. The H27XL can be programmed with up to 3 on/off settings per day with a separate programme every day of the week.The 103 third parties who use cookies on this service do so for their purposes of displaying and measuring personalized ads, generating audience insights, and developing and improving products.

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 single, two and four channel versions are voltage free as standard and use the same backplate as Horstmann's 425 and 5 Series programmers.

I currently have a Horstmann H27XL programmer, as shown in the attached photo, a Bermuda Baxi boiler and a hot water cylinder which is in a cupboard upstairs. 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. 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.
