1 Introduction
1.1 TheTAC 200 Heating Controller
The TAC 200 is a controller for different heating systems.
TAC 200 may be operated with or without a room sensor.
It also compensates for the outdoor temperature in different ways.
The controller has an easy-to-use operator interface and needs virtually
no maintenance.
1.2 This manual
This manual has the following contents.
Chapter 2
Shows how the TAC 200 is mounted, connected and commissioned.
There is also a description of the operator interface with its symbols. To
show the usage of the operating keys, there is a detailed description on
how to set the date and time.
After the time has been set, the TAC 200 immediately starts working with
default values.
Chapter 3
This chapter describes the daily operations on the TAC 200. You can
read temperature values, enter setpoint values and change the time
programs for day and night time operation.
Chapter 4
When a plant is commissioned and fine-tuned, it may be necessary to
adjust some of the parameters. The controller function and available
parameters are described in chapter 4.
Chapter 5
This is a summary of the technical data of the TAC 200. There is also a
list of all the default values used at a restart.
At the end of the manual there is a commissioning protocol, where
entered values should be noted.

1.3 More information
TAC 200 is also described in the following documents, available in
Swedish, English and several other languages:
•Data sheet TAC 200
The data sheet contains a comprehensive specification of the controller
and should be read together with the User’s Manual.
•List of functions in TAC 200
A small leaflet normally placed in a slot in the operator’s panel.
•Installation instruction TAC 200
0FL-3492-002 is a description for installation and start-up, packed
together with the unit. The contents are a condensed version of chapter 2
in this manual and a graphic mounting instruction.

2.1 Mounting
Type TAC 200 controller
The TAC 200 has a plastic enclosure with a transparent cover. Install the
controllerinaccordancewiththeenclosedinstructions.Placethecontrollerso
that you can easily adjust and read the display.
Cable entries for cables from sensors and actuators are provided for in the
mountingandterminalplate.
Type EGU outdoor sensor
Mount the sensor on an external wall facing north or northwest. The sensor
should be located about 3 m above the ground and the cable entry should be
orienteddownwards.
Type EGWS/EGA water temperature sensors
Install the EGWS pipe sensor in the riser pipe 0.5-1 m downstream of the
shunt valve. If a clamp-on sensor is fitted, mount this on an uninsulated part of
the riser pipe. Carefully rub down the pipe so that the copper plate of the
sensor will make good contact.

Type EGF 1 or EGRL room temperature sensors
To ensure the best possible results, observe the following when installing the
roomtemperaturesensor.
Thesensor mustbelocated ina roomwhichis typicalforthe building.
Theroommustbesufficientlylargesothatnowidetemperaturevariationswill
occur due to local heat sources, such as machines or occupants.
Theroom mustnot beequipped withthermostatic valves.
Locate the room sensor so that its time constant will be as short as possible. To
achievethis:
–Mount the sensor on an inner wall made of lightweight building material,
such as wood or plasterboard. Avoid mounting it on a concrete wall.
–Mount the sensor in an open location to ensure good circulation of air
aroundit.
–Locate the sensor within 10 m from a radiator, but not directly above a
radiator.Thisisparticularlyimportantinroomswithoutmechanical
ventilation.Theairvelocitiesarethenoftenlow,whichwillcauseasluggish

Type M44, M5, M15, M42 actuators
Installation instructions for actuators are supplied together with the actuator
and its its installation kit.

TAC 200 User’s Manual
There are two types of on/off control (selected by the DIP-switch settings, see
2.4).
On/off in two steps: Step 1 Step 2
Stage 1 ••
Stage 2 •
On/off in three steps: Step 1 Step 2 Step 3

Connections on the terminal unit.
TAC 200 has six knock-out holes for cable entries:
–2 knock-outs in the rear part for conduit fitting Pr 18.6 (Pg 11)
–2 knock-outs (for cables with rubber bushings) on the upper side of
the case
–2 knock-outs (for cables with rubber bushings) on the lower side of
the case
High voltage cables must be kept well separated from the low voltage
cables.
Connections (also any connections of 24 V to the actuators) must be
performed according to the high voltage regulations.
