Temporary Overrides - Danfoss 102 Installation & User's Instructions

Overriding the programe using the
Pre-Selector wheel
The pre-selector wheel can be used
to override the set programme on
occasions when you need to change
from your normal heating routine.
By turning the wheel anti-clockwise
you can turn the unit ON when it is
OFF and vice versa.
Example:
Your programme is set so that your heating comes on
at 4pm but you arrive home earlier than usual, at 2pm
and need the heating ON immediately.
Turn the wheel anti-clockwise until it displays ON
UNTIL `D' as shown.
Thus the system is turned ON manually at 2pm but will
revert to the set programme at the next operation (i.e.
OFF at 11pm)
Some other useful pre-selections are:
ALL DAY ON (1 ON/1 OFF)
Turn the Wheel to display "ON UNTIL D".
ALL DAY OFF
Turn the Wheel to display "OFF UNTIL A".
!
Note: Do not operate the pre-selector whilst a tappet
is close to the TIME mark. This may cause the time
of day setting of the clock to be altered, and the time
would then need to be reset as shown on page 8.
