Rated 5 out of 5 by from Brilliant Easy Replacement Couldnt believe they still make this control unit. My old one after 30 years, yes 30 years , started to misbehave with wear on one of the switch off noddules. Found that its still made, and was an easy change over for the front panel, wiring didnt need to be touched.

Rated 4 out of 5 by from Horstmann Tiara 25 The Horstmann Tiara 25 timer packed up after many years of trouble free service so I needed a quick replacement, so power off, undo two screws and pulled off timer front then replaced with new one, two screws tightened, power on and we were back to trouble free heating and hot water. Screwfix click and collect proved excellent and they offered the cheapest price therefore they come well recommended

Rated 4 out of 5 by from Horstmann 425 Generally a very simple to use CH programmer. Don't make the mistake of model types if you want the neon 'on' 'off' indicators which are not on this model. The step forward is a very useful function although the step numbers are difficult to see if you are installing for someone who may not have good vision.

Rated 4 out of 5 by from Ok programmer A basic non digital programmer for people that don't like setting digital over complicated timers.will suit the old that have basic boiler/ pump central heating systems.
