Running your programme The 102E5 will either control your hot water and heating together, or just your hot water (i.e. during the summer, when heating is no longer required).
Temporary User Overrides Sometimes you may need to change the way you use your heating temporarily, i.e due to unusually cold weather. The 102E5 has two convenient overrides which can be selected without affecting the set programme. Override buttons Override buttons +1HOUR Press +1HOUR once if you need an extra hour of operation (a red light will come on). If the system is off it will come on for an hour. If it is already on it will add an extra hour so the system stays on for an extra hour.
Battery backup In the event of a power cut, the built-in lithium battery will keep your time and programme settings for up to 15 days. After 15 days without mains power the unit will switch off and two dots will show in the display. However all your programmed on/off times will be remembered. Battery backup When the mains power is restored, the unit will need to be reactivated by pressing the PROGRAMME button, and the time and day will need to be set (see page 13).
