Operation

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).

1.1.1 Operating keys

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

Operation

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.

2.1 Setting the system code number and control method

Start-up

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:

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 indi­cates 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.

The sensor calibration is performed in the configuration level.

Fb17 = ON: Pt 100 and Pt 1000 sensors

The values measured by all the connected sensors can be changed or reset. To proceed, set
the sensor value displayed to the temperature measured directly at the measuring point (ref
erence temperature).
Activate calibration with Fb1 to Fb7.
An incorrect calibration can be deleted by setting Fb1 to F7 = OFF.

How to proceed:

Change to the configuration and parameter level.

CO

Select
Enter the configuration level.
Press the upward arrow key until Fb25 appears on the display.

(This function block is merely selected to enter the code number. Another function
block that is protected by the code number can be also used.)

Press the enter key.
Enter and confirm the code number (–> section ) .

Close function block Fb 25.
Select the function block of the sensor that is to be calibrated (Fb1 to Fb7):

Fb1: Supply air sensor
Fb2: Exhaust air sensor
Fb3: Outdoor sensor
Fb4: Return flow sensor, heating coil
Fb5: Room sensor
Fb6: Return flow sensor, HR (system 3 and 5)
Fb7: Mixed air or extract air sensor (system 2 and 4)

Press the enter key.
A temperature appears on the display.

2.5 Entering the key number

Several functions are protected against unintentional and unauthorized access. These func
tions can only be altered when the code number is known. The code number is written on
page 116. Tear out this page or blank out the code number to prevent its unauthorized use.

How to proceed:

appears on the display.
Press the arrow key until the correct code number appears on the display.
Confirm the code number.

When the correct code number is confirmed, the function block that should be
changed starts to blink quickly on the display.

The code number remains active for approx. three minutes.

2.6 Resetting default setting

Parameters from the parameter level can be reset to their default values (factory settings).

How to proceed:

Press the reset key with a pencil, etc.
All the parameters are reset to the factory setting (WE).

In systems with several pumps, select the pumps using the key.
The associated symbol blinks in the system diagram.
When the pumps are deactivated, just the pump circuit blinks on the display.

4. Slide the operating mode switch from to exit the manual operating mode.

Note!

In manual operation mode, the user can set the outputs anyway as required. On selecting
the manual operation mode, all limit temperatures and logical links ceased to be in force.
The user has absolute control and takes on responsibility for interaction between all the out

­puts and the resulting consequences. A frost protection thermostat (Fb15 = ON) connected to
the controllers keeps functioning even in manual operation mode.
