What is a Channel Programmer?

An explanation for householders
Programmers allow you to set ‘On’ and ‘Off’ time periods.
Some models switch the Central Heating and domestic Hot Water on and off at the same time, while others allow the domestic Hot Water and Central Heating to come on and go off at different times. Set the ‘On’ and ‘Off’ time periods to suit your own lifestyle.
On some programmers you must also set whether you want the Central Heating and Hot Water to run continuously, run under the chosen ‘On’ and ‘Off’ heating periods, or be permanently off. The time on the programmer must be correct. Some types have to be adjusted in Spring and Autumn upon the changes between Winter and Summer time.
You may be able to temporarily adjust the heating programme, for example, ‘Override’,‘Advance’ or ‘Boost’. These are explained in the manufacturer’s instructions. The Central Heating will not work if the room thermostat has switched the Central Heating off. And, if you have a Hot Water cylinder, the water heating will not work if the cylinder thermostat detects that the Central Hot Water has reached the correct temperature.
Introduction to the 1 Channel Programmer
This programmer can automatically switch your Central Heating and Hot Water ON and OFF either 2 or 3 times a day, at whatever times you choose. Timekeeping is maintained through power interruptions by a replaceable internal battery (by Qualified Installer/Electrician only) designed to last for the lifetime of the programmer and the clock is automatically put forward 1 hour at 1:00am on the last Sunday of March and back 1 hour at 2:00am on the last Sunday of October. The clock is factory pre-set to UK time and date, but you can alter it if you want. During installation, the installer selects 24 hour, 5/2 day, or 7 day programming and either 2 or 3 on/off periods per day, via the Technical Settings (see installation instructions).
The large, easy to read display makes programming easy and the unit is designed to eliminate the possibility of accidental changes to your programme. Buttons normally visible, only affect your set programme temporarily. All buttons which can permanently change your programme are located behind the flip over facia.

• The 24 hour programmer option runs the same programme every day.
• The 5/2 Day programmer option allows different ON/ OFF times at weekends.
•  The 7 Day programmer option allows different ON/OFF times for each day of the week.

IMPORTANT: This programmer is not suitable for the switching of devices greater than 6Amp rated. (e.g. Not suitable for use as an immersion timer)
