Horstmann 425 Tiara Programmer 4.2 5 21 21
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. 17 Jan 2015
basic timer I bought and fitted this timer for my mother ,who is 75 years old.i know if I bought an all singing all dancing timer I would be round at her house every day showing her how to use it and what each button did.she doesn't need a 5/2 day timer or one that knows when you're on holiday.its simple it does the job 19 Dec 2014
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. 14 Dec 2014
Compatable replacement. I'm an electrical contractor. I was called to a house that had a Horstmann Diamond programmer built in the 60's which was now sometimes sticking. I Spoke to Horstmann technical who suggested Horstmann 425 Tiara Programmer. What an excellent choice, a breeze to install and all working o.k.. If this one lasts as long as the old Horstmann Diamond, the customer will be well happy. This item was cheaper from Screwfix than any of my electrical wholesalers. Well done Screwfix. 23 Jul 2014
