Hi – I have recently replaced my central heating boiler with a wall mounted Valiant Boiler - it is fully pumped & is NOT A COMBI-BOILER. I now find that the programmer switch is about 20 years old like the old boiler which needs to be replaced with one which enables one to control the switching on and off the heating and hot water supply independently of each other & to set a time for hot water & central heating to come on for Monday to Friday and a different time for Saturday and yet a slightly time for Sunday. To have a programmer which switches automatically to winter / summer times would be a bonus. Can you please let me which are the two best (in terms of reliability and ease of use) programmers you can offer me. I am having difficulty going through your list of programmers as there so many. Full boiler model details re :  VAILLANT - Eco Tec PLus 428  -  Wall mounted.


Thank you for your enquiry - Please find product page link for the Vaillant 140 Programmer which fits into your boiler fascia.  and with the combi boiler has to be used in conjuction with te VR 65 Control Centre.
