Horstmann Diadem Programmer
The Horstmann Diadem 425 is a two channel heating programmer, designed for controlling hot water and central heating systems. The mechanical control is simple to use and allows for a quick change to the programming. Installation of the 425 Diadem is simplified through the use of a 9 way industry standard backplate, this also makes replacing old models easier.
Horstmann have given the 425 Diadem an ‘advance’ feature which lets the user switch the heating on or off quickly to override the programme.
For fully pumped central heating systems the Horstmann 425 Diadem has 16 programmes including independent programming of heating and hot water. For gravity systems it offers 10 programmes. The Diadem is ideal for gravity central heating systems and fully pumped central heating systems with zone valves.
