In rooms which are heated and / or cooled by a f an coil
unit, the Contouch can be used as a control panel for the
ventilator control.
The current fan speed is shown on the display.
In manual operation, the speed level of the fan can be
set by the rotary control on the Contouch.
At speed level "0", the fan switches off and a possibly
open valve closes, i.e. the room is then neither heated
nor cooled. If the setpoi nt for heat protection is then ex-
ceed ed or the setpoint for fr ost prot ection fallen short of,
au tomat i c m ode b ecom es act iv e i n th e cas e of a co nti n-
uous controller and the fan is switched to t he highest fan
speed if a two-point controller is used. The controller
heats or cools until reaching the setpoint of the previous-
ly set operating mode.
With option "A", the Contouch rotary control is used to
set the fan control to automatic mode. Then the speed is
specified by the control system.
The display lighting switches on when Contouch is oper-
ated. The lighting switches off after a certain time period,
which must be configured. The device is in standby
mode.
Time programs with weekl y switching plans can be con-
figured for the 18 room operating functions and for set-
ti ng the room operating mode of the controll er. Up to 16
switching points can be set for each time switch pro-
gram. The time switch programs for setting the room op-
erating mode are ac tivated in automatic mode.
Contouch off ers a cleaning function. If this has been ac-
tivated by the touchscreen, the n the device is blocked for
servicing for a specific time period, which must be con-
fig ured. The device, in particular the touchscreen, can be
cleaned without triggering unwanted functions.
The internal Contouch signal generator provides the
acoustic displa y of alarm messa ges a nd can be us ed as
a response when a button is activated.
You use the ETS3 (Version 3 and higher) to select the
application program, to allocate specific parameters and
addresses and to transfer these into the Contouch UP
204 room controller.

The bus coupler contained in the scope of supply make
it possible to connect the Contouch to the bus line by
means of its user interface.
The telegrams receiv ed through th e bus line are
processed by the bus coupl er and forwarded to
Contouch. In the opposite direction, si gnals coming from
Contouch are converted into telegrams and sent through
the bus.
The bus coupler is connected directly to the bus, where
it monitors this constantly and is therefore always in-
formed as to whether the bus line is free or busy with
telegrams. If an event occurs and the bus line is free, the
bus coupler begins sending immediately. Otherwise the
s ending req uest is stored until the bus line is free.
Note: Contouch can only be used together with the sup-
plie d bus coup le r.
