The Extra Hour Function (for Heating and/or Hot Water)
The EXTRA HOUR buttons allow you to switch the heating or hot water ON for up to
3 extra hours without altering the programme. Pressing either button once will give
one extra hour. The LoT™ Display will display the message ‘+ 1 HOUR’, to confirm
the button has been pressed.
When the green INDICATOR LAMP is OFF, pressing an EXTRA HOUR button
switches the heating or hot water ON for just one hour.
When the green INDICATOR LAMP is ON, pressing an EXTRA HOUR button
extends the programmed ON period by one hour.
Further presses of the EXTRA HOUR buttons will increase the extra hour period by
one hour for each button press, up to a maximum of 3 hours. The LoT™ Display will
continue to provide information on the extra hour status.
To cancel the extra hours, just keep pressing the EXTRA HOUR button until the
‘CANCELLED’ message appears on the LoT™ Display.
The Holiday Function
The Holiday function allows you to switch off your heating and hot water for a specified

If you have made a change to the number of days, the message ‘DAYS AWAY OK ?’
will appear. Press the green button to confirm your selection.

The message ‘SAVED’ will be displayed for a few seconds, followed by the date you
return, to enable you to check you have programmed the holiday function correctly.

HOLIDAY’ and the display will count down the number of days till you return.
To cancel the Holiday function:
f. To cancel the Holiday function, just press the HOLIDAY button again. The LoT™

normal operation.
