Installing the control unit
The cable for the control unit is connected to the contact under the small cover. Find a suitable po-
sition for the control unit in the passenger compartment. Clean the surfaces carefully with a suitable
grease solvent (for instance Acrysol). Do not use acetone, trichlorethylene, Breakclean or similar
products as PVC and plastic may be damaged. Fasten the control unit by means of the enclosed
double-sided tape. Note that the two ends of the cover are different. It can only be opened
from one end(I). If the outside temperature sensor is enclosed, fit this in the front of the car, and
place it so that hot parts do not influence it. For wiring, see the wiring diagram.
Installing the relay box
The relay box should be fastened with enclosed car body screw or strips. For wiring,
see the wiring diagram. Instal the relay box in the engine compartment in a position
far away from moving or warm parts. NOTE: The box must be installed in such a way
that the outlet side slopes downwards in case any water should accumulate. Outlets
which are not in use should be blanked off, using the enclosed plugs. timer.
Using the control unit
The control unit in the DEFA Warm Up ensures that the car is warm at the required time. The unit
has 2 drive away times (Drive away time is the time the car will be used) functioning indepen-
dently of each other. These times are 24 hours repetitive, suitable for car owners using the car at
the same time every day. In addition to being an advanced control unit for the DEFA Warm Up, the
unit is equipped with a number of other functions: outside temperature, ice warning device, battery
voltage/charging voltage. The display lighting on the unit is lit when the engine is running or when
one of the buttons is pressed.
