Horstmann H27XL Programmer, Multi

Product Information

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. 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. 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. The new timer works perfectly well, but I know I will be facing the flat battery issue again in 7 years or so. due to a plumbing issue we now have to wire a second boiler alongside another in a reasonable size house.

Our previous model with exactly the same programming procedure the heating setting was the key control.

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. Also useful are the Boost override buttons which allows y ou to bring on the heating and / or hot water for 1 or 2 hours at any time. 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. Takes a bit of navigation through the menus but very easy to program once you get used to what the buttons do. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice.

It is a very strong fit, so you need to apply a fair amount of leverage to get the old one off and need to press the new one on firmly until it has fully engaged. 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.
