1 Scope of the ventilation controller
The TROVIS 5177 Ventilation Controller is
designed for controlling and monitoring air
handling systems, ranging from simple air
heaters right up to complex ventilation and
air conditioning systems that contain heating
coils, mixed air chambers, cooling coils,
humidifiers and heat recovery units.
These mounting and operating instructions
will enable you to operate the switches and
keys of this controller as well as give an
explanation of the electrical connection and
mounting procedure. Also the extensive possi-
bilities for configuration and
parameterization are described. Please note
that changes in configuration and
parameterization require specialized knowl-
edge on ventilation technology!
After the controller has been connected to the
power supply, it is basically ready for opera-
tion. Since the controller functions according
to time schedules, make sure the time and
date are set before start-up. Refer to page 22
onwards for step-by-step instructions on how
to set the time and date.
The controller also saves information on con-
figuration and parameters in a memory that
can function for a long time without a power
supply. Only the time and date need to be
reset after a power failure.
The controller contains default setting to oper-
ate the ventilation system from 07.00 to
22.00 hours. If the two-speed fans are acti-
vated, the default setting for time-of-use
between 10.00 and 15.00 hours. If you want
a different time schedule for these setting,
you must change the times-of-use. Refer to
page 26 for details on how to change these
settings.
If you require more information on a certain
topic, use the subject index at the end of
these instructions.

2 Safety instructions
4Assembly, start-up and operation of this
device may only be performed by trained
and experienced personnel familiar with
this product. Proper transportation and
storage are assumed.
4The controller is intended for use in elec-
trical power installations. For wiring and
maintenance, you are required to observe
the relevant safety regulations.
4In automatic operating mode (time-con-
trolled operation), the device ensures that
all protective functions that are vital for
the system are monitored. Safety features
such as frost protection monitoring and
excess temperature protection, however,
are not active in the following cases: de-
fective controller and failure of function;
defective sensors or sensors that are not
connected or have not been deactivated;
lack of operating voltage to the controller.
4The installation and electrical wiring de-
scribed in these instructions should only
be performed by authorized personnel.
4Changing function blocks and their pa-
rameters (see Appendix A) requires spe-
cialized knowledge of ventilation systems
and should only be performed by trained
staff.

3 Operation
To understand the operation of this control-
ler, use the fold-out page at the end of these
mounting and operating instructions!
The controller is operated over switches and
keys. They are accessible after the clear front
door is opened. The mode switch (A)
switches between the various operating
modes. You can view parameters such as
temperatures and set points using switch (C)
and the keys (H) and (I) as well as determine
the selectable functions and controller param-
eters. During which, you can access the vari-
ous levels described in section 3.3. All set-
tings made and the information required
appear on the display (G).
It is also possible to transfer configuration
and parameterization data with a memory
module in the controller, refer to section .
The following sections contain a description
of the individual switches and keys as well as
concerning the operation of the individual
levels.
3.1 Operating controls on front panel
3.1.1 Mo e switch (A)
Use this switch to select the operating mode:
Automatic operation: Rate opera-
tion/stan -by operation: The control-
ler works according to set times-of-use
and switches between rated and
stand-by operation.
Automatic operation: Rate opera-
tion/re uce operation: The control-
ler works according to set times-of-use
and switches between rated and, in
contrast to previous mode, reduced
operation.
Rate operation: The ventilation sys-
tem is constantly in operation. It is
controlled acc. to the set point(s) for
day, e.g. Supply air day set point.
Re uce operation: The ventilation
system is constantly in operation. It is
controlled acc. to the set point(s) for
night, e.g. Supply air night set point.
Stan -by operation: The ventilation
system is switched off. The frost protec-
tion is active, provided it has been
enabled, see section 5.7.1
Manual operation: In combination
with the selection switch for manual
operation (B), the ventilation controller
can be operated in the manual mode,
see section 3.2.

If the mode switch (A) is set to manual mode
and the manual level is activated, you can
use this switch to operate the output which
you have selected over the selection switch
for manual operation (B), see section 3.2.

3.1.3 Changeover key an reset key (C, D)
Theses keys must be operated with a pointed
object (e.g. pencil). The following functions
are available:
Changeover key lets you change
between the main levels: operating
and configuration levels.
Reset key resets all parameters in
the parameter level (!) to their
default settings.
3.1.4 Set point correction switch (F)
The set point can be increased or reduced
with the aid of this switch.
−Set point is reduced by 1 K per
raster
0 No change in set point
+ Set point is increased by 1 K per
raster

3.1.5 Arrow keys an enter key (H, I)
Arrow keys let you scroll within lev-
els, select parameters and function
blocks as well as increase and
reduce values
Enter key lets you activate levels,
parameters, function blocks as well
as confirm changed values
3.2 Manual mo e
Note!
In manual mode, the user can set the outputs anyway as required. On selecting the man-
ual mode, all limit temperatures and logical links ceased to be in force. The user has ab-
solute control and takes on responsibility for interaction between all the outputs and the
resulting consequences.
As soon as you set the mode switch to the
switch position, all operating states of the
controller outputs are frozen, i.e. the con-
trol signals as well as the switching states of
the binary outputs from automatic operation
are kept regardless of the input variables. If
you have changed the output variables over
manual mode, these states are maintained
until you exit the manual mode.
The system frost protection is guaranteed pro-
vided that the function block Co5 Fb15= ON
is activated.
