USER INSTRUCTIONS
The Danfoss Randall 106 Timeswitch controls your heating and
Hot Water systems automatically, to save you the trouble of
switching manually every day - and also economises on fuel by
turning the systems off when you do not normally need them.
Normally the timeswitch dial provides 2 ON periods and 2 OFF
periods each 24 hours.

1. Setting the Programme

i) Remove the dial cover by pulling it off .
ii) Decide when you want the ON periods. While gripping the dial knob slide
the dial tappets fi rmly, as shown. The tappets may be quite stiff to move.
Example 1. If you want the switch ON between 4 p.m. (16.00 hours) and
11 p.m. (23.00 hours), set the tappets as shown. (A to 8, B to 10, C to 16,
D to 23).
Remember :- Red tappets switch ON
Blue tappets switch OFF
iii) Ensure that the installer has removed the protective tape covering the
pre-selector wheel.
iv) Using the dial knob rotate the dial completely at least twice, clockwise
only, to clear the mechanism.

the dial knob, rotate the dial clockwise only unitl `15' on the dial is next to

when all the clocks change by one hour in Spring and Autumn.

the dial clockwise only.
