 Necessary action
2 Safety
2.1 Qualifications of installation person-
nel
The installation personnel must have the following qualifications:
■Successful completion of Webasto training
■Corresponding qualification for working on technical systems
2.2 Regulations and legal requirements
 Read and follow the operating instructions before starting up
the heater.
Directives Type-approval numbers for MultiControl | SmartCon-
trol | Unibox
Radio interfe-
rence ECE R10 04 7319 MultiControl|SmartControl
The regulations of these guidelines are binding in the scope of the
Directive 70/156/EEC and/or 2007/46/EC (for new vehicle models
from 29/04/2009) and should also be observed in countries in which
there are no special regulations. Failure to follow the installation
instructions will result in the invalidation of the type approval for
the heater and therefore invalidation of the general homologation
of the vehicle. For vehicles with an EU type approval, an entry is not
required in accordance with § 19 section 4 of appendix VIII b of
StVZO. Country-specific registration regulations must be complied
with.
The variants MultiControl MAR/RV TT and MAR/RV ATE do not
comply with the legal requirements of UN/ECE Regulation No. 21
(interior fittings). These may therefore not be fitted in the head
impact zone (on the dashboard). This does not include fitting in the
exempted area behind the steering wheel with a deviation of up to
125mm from the outer edge of the steering wheel. In the case of
adjustable steering wheels, the zone finally exempted is reduced to
the common area of the exempted zones for each of the driving
positions which the steering wheel may assume. Please refer to the
current version of UN/ECE R21.
Intended use
The control element MultiControl | SmartControl is used to operate
the Webasto water or air heaters for cabin and engine preheating.
The control element MultiControl | SmartControl is currently ap-
proved for connection to certain Webasto water or air heaters.

DANGER
■Do not operate the heater in closed rooms due to
the danger of poisoning and suffocation.
■Always switch off the heater before refuelling.
■The improper operation, installation or repair of
Webasto heaters and control elements can cause fire
or the leakage of deadly carbon monoxide. This can
lead to serious injury or death.
■Webasto shall not assume liability for defects or
damage that are the result that the installation and
operating instructions as well as the instructions
contained therein being disregarded.
This liability exclusion particularly applies for:
■installation by untrained personnel
■improper use
■repairs not carried out by a Webasto service
workshop
■use of non-genuine parts
■Conversion of the heater without permission from
Webasto
■If faulty always replace the complete control ele-
ment.

UniBox
The UniBox makes it possible to operate heaters that are not
W-bus compatible using the MultiControl and SmartControl
control elements. The UniBox also provides additional inputs and
outputs to expand the functional scope.
Communication between the UniBox and the control element
takes place via the W-bus. The UniBox is configured automatically
when the heater is selected on the control element.
The UniBox is fitted in the area of the vehicle that is not visible to
the customer.
3.4 Versions
The control element is available in two versions:
■SmartControl: control element with black frame and no timer
function.
■MultiControl: control element with silver-coloured frame, with
timer function.
