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.

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.

3.3 Control levels
Note!
Any changes in the configuration level (PA and CO levels) may cause errors in the sys-
tem. Therefore, they must be only performed by the specialist!
Fig. 1 shows the level structure in the
TROVIS 5177 Ventilation Controller. It also
shows the operating steps that need to be
taken to access each individual level. The con-
troller contains two main levels: the operat-
ing level and the configuration level. Use the
changeover key (C) to switch between the lev-
els. The operating level contains the info lev-
els, in addition to this, when switched to the
manual mode, a manual level is also accessi-
ble. The configuration level contains the
parameter levels, the system code number
level and the configuration levels. The info,
parameter and configuration levels are
assigned to an index from 1 to 9 which is the
same in all three levels. In this way, specifica-
tions concerning the heating coil are always
termed InF1, PA1 und Co1 (index 1) accord-
ing to the level. All other indices are summa-
rized in the table opposite.
Usually, the ventilation controller is in the
operating level and the time appears on the
display. In Fig. 1, for example, 10:24 is
indicated on the display. Apart from the
time, symbols to represent the operating
mode and operating status as well as the sys-
tem represented symbolically appear on the
display. Refer to page 147 for a summary
of the major symbols.
A bar graph appears on bottom right-hand
corner of the display, showing roughly the
control signals Y1, Y2 and Y3. This bar
graph is shown in the operating level.
Note: Two minutes after the last entry, the
controller returns automatically from the
configuration level back to the operating
level.

3.3.1 Info levels
Information is displayed in the info levels
(InF1 to InF5) about, for example, the operat-
ing states of the pumps and fans, or control
signals and values of the temperature sen-
sors. The system code number and configura-
tion determine what sort of information is
shown on the display. Refer to Appendix C
for a summary of symbols that appear on the
display and their meanings.
It is not possible to make any changes to
parameters when the controller is in an info
level.

3.3.2 Changing the system co e number
The ventilation controller contains different
types of systems which are assigned to sys-
tem code numbers 0 to 9. They are deter-
mined in the configuration level under Anl
(system code number). By entering the system
code number, you determine both the inputs
and outputs of the controller as well as the
selectable function blocks and parameters.
You can find a list of the different systems in
section 4.
Every change in system code number or con-
trol method (supply air control, exhaust air
control) causes the assignment of sensors to
be reprogrammed: the sensor inputs required
for the function blocks are activated and the
sensor inputs not used are deactivated. These
settings can be changed manually.
Proceed as follows to change the system
code number:

3.3.3 Control metho
You can choose between the following con-
trol methods for all systems:
4Supply air temperature control,
4Exhaust air temperature control,
4Exhaust air temperature cascade control,
4Room temperature control or
4Room temperature cascade control.
For systems Anl 6, and 9 (air-conditioning
systems) the control method needs to be set
for the temperature control circuit as well as
for the humidity control circuit. For the humid-
ity circuit, you can choose between:
4Supply air humidity control,
4Exhaust air humidity control,
4Exhaust air humidity cascade control,
4Room humidity control or
4Room humidity cascade control.
The difference between temperature and
humidity control circuits is shown on the dis-
play by blinking symbols. For the tempera-
ture control circuit, heating and cooling coil
blink on the display. For the humidity control
circuit, the cooling coil and humidifier blink
on the display. Additionally, for the humidity
control circuit, a difference is made between
humidifying and dehumidifying operation
and just humidifier operation.
You can set the control method in the configu-
ration level under the system code number
Anl. Refer to Changing the system code
number in section 3.3.2 on page 16.
