Choosing the right Honeywell Home Electronic Programmer 24 Hour ST9400A1002, is an important decision, and it's one we're sure to help you get right.Heating and hot water systems based on boilers account for of this fi gure, so it is important to understand how your controls can help to maximize energy effi ciency while maintaining your comfort. In the Winter the Central Heating is set to Once a day (the Heating being controlled by the room state) - early morning to late at night, the Hot Water remains on its Auto setting. I have a Combi boiler, and the Hot Water control is wired into the boiler 'Pre Heat' (Tip: with Pre Heat On opening a hot tap for a couple of seconds signals hot water required - give time for the boiler to heat up the Hot Water heat exchange before running off hot water - saves lots of water and gets you hot water quicker, also if the boiler valve is in the Central Heating position it needs time to change over). We're sorry but this product has now been discontinued by Honeywell Heating Supplies and can no longer be purchased.
