Set required comfort temperature with control (1) and economy temperature with control (2).
The action of the timer will switch the heater operation between setting (1) and setting (2) at the appropriate programme times.
When the economy setting is active the green indicator will glow, when the comfort setting is active the red indicator will glow,
when the thermostat calls for heat the amber indicator will also glow. If the override button is pressed the programme
action will be reversed for the remainder of the programme period. Green operation will become red or visa versa,

but pressing the Start button (9) while a day is selected will reset the time. See note below.
NOTE
The action of the start button (9) automatically sets the time to 12am (noon) and all programme times run from this setting.
Starting the timer should be carried out at mid-day, but programme times may be shifted by starting the timer earlier or later.
