5. Installation
5.1 Base station
5.2 Mobile unit
6. Electrical connection
The base station is supplied with power by the controller
via the VBus®, a mains connection is not required. The VBus®-
cable has to be connected to the VBus® terminals (either
polarity).
The cable carries low voltage and must not run together
in a cable conduit with cables carrying a higher voltage than
50 V (please pay attention to the valid local regulations!).The
cross section must be at least 0,5 mm2 and the cable can
be extended up to 50 m in the case of a single connection.
The bus cable can be extended with a two-wire cable (bell
wire).
• Connect the cable to the VBus®- terminals of the con-
troller or module.
ATTENTION!
Avoid damage caused by electrostatic
discharge. Before beginning any interven-
tion, divert charges by touching metallic
surfaces, such as radiators and water
taps!

6.1 Base station
Mounting in dry interior locations only!
• Unscrew the screw from the upper part of the housing
and remove it along with the housing.
• Mount the lower part of the housing to the wall or mount
it into an in-wall box.
• The printed circuit board with the VBus®-terminals is lo-
cated inside the upper part of the housing. Connect the
VBus®-cable of the controller or the module respectively
to the VBus®-terminals of the base station (1) with either
polarity.
• Attach the upper part of the housing to the lower part of
the housing by means of the screw.
The mobile unit can be used as a hand-held unit or as
a wall-mounted unit. If it is used as a hand-held unit, the
stored values will be displayed, but new values will not be
received. To receive new data, the DFA comfort has to be
attached to the base station on the wall.

7. Changing the rechargeable batteries • Open the cover of the rechargeable battery compart-
ment in order to change the batteries. Replace the
rechargeable batteries with two new ones. Close the
cover.
Note:
Use rechargeable batteries by the same manu-
facturer only.
The mobile unit is supplied with energy via rechargeable
batteries (2 x rechargeable batteries AA Ni-MH, 1800 mAh).
As soon as the mobile unit is attached to the base station,
it will be supplied with energy via the base station and the
batteries will be recharged. Charging time is approx. 40
hours and standby time approx. 15 hours.
The rechargeable batteries are delivered uncharged and have
to be fully charged before the first usage. In order to shorten
the charging time, the rechargeable batteries can be charged
in a standard charger.
6.2 Mobile unit
Note: Fully discharging the rechargeable bat-
teries can shorten their lifespan. To avoid full
discharge, attach the mobile unit to the base
station after every use.
8. Operation and function
