What’s new compared to previous version (1.9)
Compared to the firmware version 1.9, the following changes have been made:
4A two-second delay before a sensor failure is detected and before a binary input state
changes to suppress error messages caused by signal distortion.
4The system bus interface can be switched over from 8-bit addressing to 16-bit addressing
(Fb44).
4When the modem is in operation, if you keep the enter key pressed when the time ap-
pears on the display, the current connection status “Free”, “Call”, “Conn” or “Ring” is
shown.

1 Operation
1.1 Operating controls
The TROVIS 5477 Ventilation Controller can be operated using the operating controls on the
front panel.
The controller is ready for operation using its default temperature and time schedule settings.
On start-up, after switching on the power supply, the correct time and date must be set in
the controller (–> section 1.5).

The operating keys are located on the front of the controller and protected by a transparent
cover.
Changeover key
(press with pencil or similar pointed object)
Allows you to change between the operating level, parameter level and
configuration level.
Reset key
(press with pencil or similar pointed object)
Allows you to reset all freely accessible parameters to default values (factory
setting). This key’s function is only active on the parameter level

1.3 Display
During operation, the display indicates the current time as well as information about the op-
eration of the controller. The times-of-use are represented by black squares below the row of
numbers at the top of the display. Symbols indicate the operating status of the controller.
See section 1.4 for more information about how to read the current status of the controller in
the operating level.

1.4 Data retrieval
You can view information in the operating level concerning various temperatures, control
signals, times-of-use, public holidays, states of the binary inputs as well as the baud rate
(–> Fig. 30). Which temperatures are shown depends on the system code number and the
configuration.
You will find a list of the various displays in section .
How to proceed:
The controller shows the time.
Press the arrow key.
Every time you press the key, another dat point appears on the display.
If required, you can view other information concerning a data point.
1.5 Setting the time and date
Set the current date and time directly after start-up and after a power failure, if necessary.
You must set the time and date in the parameter level.
How to proceed:

2.1 Setting the system code number and control method
This ventilation controller allows ten different systems to be controlled. Each system is as-
signed a system code number. You can find a list of the different systems in section 4. In ad-
dition, the control method can be determined. The following control methods are available:
Control method Display
Supply air control
Exhaust air control
Exhaust air cascade control
Room control
Room cascade control
The control methods and functions of the controller are described in sections 5, 6 and 7.
Every change in system code number or control method 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.
You must set the system code number in the configuration level (see Fig. 30).
How to proceed:
Change to the configuration and parameter level.
PA appears on the display.
Select
CO level.
Press the enter key.
The currently active system code number, e.g. Anl 1, blinks on the display.
Press the enter key.
Anl and CO blink quickly.

2.2 Activating and deactivating functions
The controller is configured by setting the function blocks (Fb). You can activate or deactivate
function blocks in the configuration level
CO . On opening the configuration level, a black
square located to the right of a function block number at the top of the display indicates
whether function block is activated. The initial display shows the function blocks 1 to 24.
Scroll to the function blocks 25 to 47 to display the setting of these function blocks.
Proceed as described below to set the function block parameters.
How to proceed:
Change to the configuration and parameter level.
PA appears on the display.
Select
CO configuration level.
Enter the configuration level.
Anl appears on the display.
Select the required function block.
Confirm the function block you have selected.
Fb_ blinks.
If a function is protected,
0 appears on the display. The code number must be entered
(–> section 2.5) before a protected function block can be changed.
Press the upward arrow key to activate the function block (Fb = ON).
A black square to the right of the function block number at the top of the display indi-
cates that the function block is activated.
or alternatively:
Press the downward arrow key to deactivate the function block (Fb = OFF).
Press the enter key to acknowledge the setting.
If the function block is left open, other parameters can be set. Proceed:
The parameter appears: Carry out change and confirm it.
Exit the function block.
Repeat the steps in the gray box to set other function blocks in the open configuration level.
Press both arrow keys simultaneously to exit parameter level.
Press the changeover key to return to the operating level.
