Programmers & Time Switches
Time controls on most domestic heating and hot water systems are among the first essentials for improving home comfort and reducing running costs. They trigger the controls ‘chain of command’, sending automatically timed On and Off instructions to other system components. Each user-set, timed switching program helps to maintain desired comfort levels and prevents excessive fuel consumption by inhibiting unnecessary boiler firing.
We usually cut heating costs and sleep better in a cooler room by using a time control to automatically switch off the system late evening and on again early morning. Also, we use the same timer to set Off and On periods during the daytime for additional benefit.
Accuracy of Heating Programmer
Once you have established what type of programmer you need – a single or dual channel system, then you can choose the functionality you need.
Obviously over the course of a week, people’s heating habits change. For example Monday to Friday it might be very similar, however on Saturday/Sunday, you might require the heating to come on later in the morning.
There are essentially three types of programmer that each allow you different levels of control. There are one-day programmers that allow you to specify when the heating comes on each day but every days heating pattern will be mirrored.
These are the most basic types of programmer and while they are simplistic so potentially good for some, in terms of energy saving they are not ideal.
The next type of programmer is the 5-2 programmer, this allows you to set two heating patterns, one for a day in the average working week, and the other for a weekend day (i.e Saturday / Sunday).
