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.

3.1.2 Selection switch for manual operation (B)

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.
