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.

Questions and answers
I cant get on to the second programme when I want the heating to come on during the evening. I can do the morning but not the evening which I used to be able to do.
To set the evening program on your Sunvic 107 XLS heating controller, follow these steps:
1. Open the Fascia: Flip down the front panel to access the programming buttons.
2. Choose Programming Mode: Ensure the unit is set to the correct mode (24-hour, 5-day/2-day, or 7-day programming).
3. Set On/Off Times:
- Press the appropriate button to adjust the evening ON time.
- Use the controls to set the desired time.
- Repeat for the OFF time to specify when heating should stop.
4. Save the Settings: Confirm the times and close the fascia to prevent accidental changes.
For precise button functions, refer to the installation instructions.
