This chapter will give you enough information to be able to
handle the controller during normal operation.
Chapter 5, Installation
This chapter will show you how to install, connect and get the
controller to operate.
Chapter 6,Troubleshooting
This chapter contains measures, which you may take on your
own, to find and remedy a possible malfunction in the control
system.

Index
At the end of the handbook, you will find an index containing
page references.
1.2 How you may use this handbook
The TAC 2413 Handbook describes all the functions and procedu-
res that are needed to install, commission and use the controller.
The TAC 2413 controller, as well as other products in the
TAC 2000 family, must not be used for purposes other than that
which it was constructed for.
The installation, connection and maintenance is required to be
performed by authorized staff.
During normal operation
If you are only going to read or set temperatures and other para-
meters during normal operation, it is sufficient to read Chapter 3,
Using the operator’s panel, and Chapter 4, Day-to-day usage.
You may also make use of the Quick Reference which is located
on the front of the controller.
During installation and commissioning
If you are going to install and commission the controller, you
should read Chapter 5, Installation. The document which is in-
cluded with the controller, TAC2413 Installation instructions, may
be used for this purpose as well. The commissioning protocol is
included in that document, but it is appendix A in this handbook
as well.
During troubleshooting
When there is something wrong with the controller, you should
read Chapter 3, Using the operator’s panel,Chapter 4, Day-to-
day usage and Chapter 6, Troubleshooting.
1.3 Documentation for the controller

TAC 2413 Handbook The air handling controller TAC 2413
2 The air handling controllerTAC 2413
TAC 2413 is a digital controller which is able to control, monitor and
supervise air handling units (AHU) in buildings.
TAC 2413 controls the room temperature or the supply air temperature
by controlling a heating coil, a cooling coil and heat recovery in se-
quence. The controller also contains functions for timed operation,
alarms, pump and fan control, and so on.
TAC 2413 has a clock which may be used to set weekly and yearly
programs, as well as powerful control functions for automatic opera-
tion. Reading and setting temperatures and other parameters is a
simple process. The display window provides you with clear informa-
tion in the form of numbers and symbols.
The controller may be mounted on a norm rail EN 500 22
(TS 35 mm), in a panel or on a wall.
2.1 Function
When the AHU starts, the return air fan (FF) is always started first;
then, supply air fan (TF) starts running. Both fans start on half
speed, no matter what speed has been chosen. If full speed has
been chosen, it is activated 30 seconds later than TF starts.
During the transition from full speed to half speed operation, both
fans are stopped for 10 seconds, then, FF is started before TF.

You can choose if you want room or supply air control by using
DIP switch 1. During room control, the control is done from the
sensor GT11, or possibly GT 41, which is chosen with DIP switch
2. The supply air temperature is controlled in cascade via the sen-
sor GT21 which has a minimum and maximum limitation function.
The control signal for the heating coil actuator SV21 is 2–10 V,
but you can set it to 0–10 V by using DIP switch 7. If the heating
coil temperature drops below a set value, SV21 is opened to prov-
ide a minimum limitation. If the temperature keeps dropping in
spite of this, the AHU is stopped and a freezing alarm is tripped. If
the AHU stops, the GT81 sensor helps hold the return temperature.
The control signal for heat recovery (HEX, or VVX in the pictu-
res) is 0–10 V. The efficiency is calculated using the sensors
GT31, GT41 and GT71. An alarm is tripped if it is too low.
During defrosting, the control signal for the VVX is controlled to
an optimum setting, and if the defrosting is not complete, TF is
stopped to quicken the process further. If the defrosting will run
for too long, the AHU stops and an alarm is tripped. The alarm is
reset in the controller.
The control signal to SV51 is 2–10 V, but you may set it to 0–10 V
by using DIP switch 7. The cooling coil actuator is allowed to
control the cooling valve only when the room temperature has
reached the cooling setpoint. Both SV21 and VVX have to be
closed, and the date has to be within the summer period, for this
to apply.

3.2.1 Parameter numbers and parameter values
The controller has a list of 100 parameters ranging from 0 to 99.
Some of these parameters may be set, such as the room tempera-
ture setpoint; others, however, can only be read, such as the out-
door temperature. Some parameters are not shown if the cor-
responding function is disabled. For example, night cooling and
night heating are both disabled if there is no room sensor.
The parameter number and the parameter value constitute a
“window” for the list of parameters, see the figure below.
The and buttons are used to move the window up and
down on the list of parameters.

3.2.3 Weekly program
The weekly program is shown as a 24 hour time bar from 00:00 to
24:00 for each day of the week. The part of the bar that is filled
shows when daytime operation applies.
The symbols of the weekly program
Each field in the time bar represents 30 minutes. If the field is fil-
led, the AHU is in operation. An empty field means that the AHU
is not running.
Below the time bar, you will find the days of the week. They
show which day of the week the time bar applies to.
• MO: Monday
• TU : Tuesday
• WE: Wednesday
• TH : Thursday
• FR : Friday
• SA : Saturday
• SU : Sunday
How to set a weekly program is described in Chapter 4, in the sec-
tion Setting weekly programs for timed operation. For more in-
formation on time schedules, please refer to the section Time
schedules in Chapter 7.

3.2.5 Alarms
When there is an alarm, an alarm symbol will flash in the display
window together with the symbol of the part of the installation
that the alarm is referring to. For example, when the frost protec-
tion guard has been triggered, the alarm symbol and the heating
coil symbol will flash.

The and buttons are used to choose a parameter.
The and buttons are used to change a parameter value.
The button is used as an enter button. Each change made to
a parameter must be confirmed with this button if it is to be regis-
