What is a Channel Programmer?...
An explanation for householders
On some programmers you must also set whether you want the
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 heating will not work if the room
thermostat has switched the 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.

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 Heating to come on and
go off at different times. Set the ‘On’ and ‘Off’ time periods to suit
your own lifestyle.
