Overrides

Sometimes you may need to change the way you use your 
heating or hot water temporarily, i.e. due to unusually cold 
weather. The SET3M has one convenient override which 
can be selected without affecting the set programme. 

The RED/BLUE wheel on the lefthand corner of the unit is 
an OVERRIDE SWITCH.

  When it shows

 RED

 the clock is 

ON

  When it shows 

BLUE

 the clock is 

OFF

Manual Use

 

If you do not wish to use the timer facility, you can switch 
your heating and hot water on or off manually by using the 
OVERRIDE wheel without having to change the settings 
on the timer itself. 

To use, turn the override wheel 

anti-clockwise

 until the 

thumbwheel displays the setting you require. 

The override will automatically cancel at the next pre-set 
time change

.
