Horstmann 425TIARA Programmer, Black

Product Information

No more damage to anything although I did need to fill and strengthen the partitioning wall around where my previous attempts had ruined the structure. I am exactly at the same stage of trying to remove the same panel and only see it being stuck solid to the backplate. Sounds like you have gravity circulation for the energy supply circuit to the hot water which can be stopped with the valve. Have you also tried using central heating controllers that does not have a worthy display or are difficult to adjust? By pulling outward and generally downward I can clearly see the single wall box because I am dragging that towards me too.

Fitted new one and was slightly irked that the LCD screen on the new one is damaged - faded in places making it hard to read. We have checked 3,641 central heating control reviews, so we can show you the weighted average rating of all the central heating controls.The large tank in the loft is the cold water feed to toilets, wash basins etc, and to the hot water cylinder, which is thing in the cupboard.

The 425 Tiara is a two circuit programmer for hot water and central heating and is ideal for use with gravity systems and fully pumped systems with mid-position or zone valves.It has 16 programmes available for fully pumped systems, including independent programming of heating and hot water as well as 10 programmes for gravity hot water/pumped heating systems. permanent live and neutral for the clock and a switched live out for the hot water and another switched live out for the heating.
