Select 107 XLS User Instructions
A timeswitch allows you to set ‘On’ and ‘Off’ time periods. The timeswitch will allow you to set the ‘On’ and
‘Off’ time periods for either Hot water or Central heating to suit your own lifestyle. On some timeswitches you
must also set whether you want the heating or hot water to run continuously, run under the chosen ‘On’ and
‘Off’ heating periods, or be permanently off.
The time on the timeswitch must be correct. Some types have to be adjusted in spring and autumn at the
changes between Greenwich Mean Time and British 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 hot water has reached the
correct temperature.
