Foreword |
Foreword
This is the technical handbook for the TAC Xenta 102 controller, a zone controller for VAV applications in offices and other larger buildings.
In this second edition of the handbook, sections that were earlier complicated to the user, have been made clearer, and most of the content has been reorganized. The trouble-shooting section has been made into its own chapter, and there are now appendices in the end of the handbook; one containing setpoint calculating examples, and one containing a commissioning protocol which can be used together with chapter 3 when commissioning.
The programs in TAC Xenta 102 now have new versions. For both the system program and the application program in the controller, the versions are 1.10. If there is a service replacement in the system, all variable bindings—if the controller is run on a network—must be remade when an older or newer version of the controller is fitted. This is because the controller has got a new “Standard Program ID”. There are also three new network variables.

The zone controller TAC Xenta 102 |
2 The zone controller TAC Xenta 102
2.1 General
The zone controller TAC Xenta 102 is intended for “Variable Air Volume” (VAV) applications in offices and other large buildings. A VAV controller usually controls the temperature in a given zone by controlling the volume sub-tempered air which is supplied to the zone.
The controller’s basic functions
All controller models have a number of built-in functions which handle the normal control situation. There are four operating modes to choose from (comfort, economy, bypass, and off) and five modes to force the controller (only heating allowed, only cooling allowed, night cooling, auto, and off).
Measuring the zone temperature is made by means of a permanent thermistor sensor or a temperature node connected to the network, and setpoint calculation is made according to special methods.
There is a detailed functional description of all the basic functions in chapter 5.2.
More about functions
Apart from the controller’s basic functions, there are additional possibilities to control the climate in the zone. In section 5.3, these are described in detail, and also which external functions that may be connected, e.g. window contact sensor and occupancy sensor.

TAC Xenta 102 Handbook |
The zone controller TAC Xenta 102 |
Communication possibilities
The controller can work either as a free-standing unit, without being connected to a network during operation, or be a part of a larger system with several other units such as TAC Xenta 300/400 and other zone controllers in the TAC Xenta family (figure 2.1). A detailed description of how units work together in a larger zone system, is found in “Guide lines for zone applications”, part number 0-004-7637.
TAC Vista is an excellent tool for reading variables and as a configuration tool during commissioning and/or operation. When TAC Vista is not a part of the system, reading and configuration of variables can be made from the operating panel TAC Xenta OP, version 3.11 or later.

Figure 2.2 Wall module in the ZS100 series
In the controlled zone, there is usually a wall module from the ZS 100 series, which measures the temperature. The wall modules ZS 101–ZS 105 may very well be used together with all controller models. On the wall module (figure 2.2) there are among other things a setpoint knob and a bypass key with setting possibilities.
The setpoint knob is used to adjust the zone temperature setpoint with a maximum of ± 5 °C.
The bypass key is used to change the operating mode, and by pressing the key, an internal timer in the controller, which runs for two hours, is started. Read more about different operating modes and ways to force the controller in sections 5.2.1–5.2.2.
On all ZS 100 wall modules, the current operating mode is indicated by the position indicator (red light emitting diode) as follows:
·Steady light:
·Slow flashing:
·Fast flashing for appr. 15 s:
·Off:
Comfort or bypass mode Economy mode
Answer to “wink” command. Confirmation that the OP is connected to the correct controller
Other operating modes
There is additional information on the wall modules and how the temperatures can be adjusted locally in the zone by means of the keys in “Data sheet for ZS 101–ZS 105”, part number 0-003- 1661.

2.3 Applications
2.3.1 General
All models have this in common:
•they are intended for use together with a Belimo® VAV-Compact air flow controller. TAC Xenta 102 sends air flow setpoints to the VAV-Compact, and reads measured air flow from the air flow controller.
•they have air quality control as an option, which means that the controller can control the air flow to keep down the carbon dioxide concentration in the zone. However, the function needs a carbon dioxide sensor to be connected to the controller, electronically or via the network.
•a window contact to stop the heating and cooling functions, should a window be opened, can be connected. An occupancy sensor can detect the presence of a person in the controlled zone and change the controller from economy to comfort mode.
The window contact sensor, occupancy sensor, and air quality control are described in detail in section 5.3.2–5.3.4.
2.3.2 Air flow control only (TAC Xenta 102-B)
The controller controls the zone temperature by means of the air damper via VAV-Compact. The air flow is minimum and maximum limited. Usually the controller only uses one cooling sequence (sub-tempered air in the duct), but it can be changed to heating (hot air in the duct) given a central command.

2.3.6 Air flow control with one stage electric reheat and fan (TAC Xenta 102-EF)
The controller controls the zone temperature by sequence controlling the air flow controller (VAV-Compact) and the electric heating coil. The air flow is minimum and maximum limited. When heating, the controller controls the electric heating coil by means of a relay in combination with the fan running to increase the air circulation through the heating coil. In this application (electric reheat + fan), the minimum limitation may have separate settings for cooling and heating.

3 Installation
3.1 Mechanical installation
3.1.1 Fitting
TAC Xenta 102 can either be snapped onto a DIN rail (figure 3.1) or fastened with two screws to a level surface (figure 3.2). On the controllers which controls equipment with 230 V supply, a semi-protection which covers the relay terminals, should be fitted (figure 3.3). A semi-protection is delivered together with these controllers.
To fasten the controller onto a DIN rail:
1.Place the controller on the top of the rail as is shown by arrow 1.
2.Turn the controller downwards until it snaps onto the rail as is indicated by arrow 2.
3.To remove, place a screwdriver in the lock on the bottom of the controller and pull down. Then it is possible to lift the controller diagonally upwards and off the rail.

Installation |
Fastening the controller on a level surface:
Use the two sockets provided for fastening the controller; the maximum screw size is M4 or ST 3,5. The head of the screw should not exceed 7,5 mm in diameter.

To fit the semi-protection:
When the cables are secured, the protection is fitted by means of the enclosed screw.

3.2 Electrical installation
3.2.1 General
!
Warning! All 230 V supply cables must be installed by authorised electricians.
1.Each controller or group of controllers must be fitted with max. 6 A fuses.
2.Secure the cables to the controller by means of clamps or similar, to limit their mobility.
3.Wire straps or shrinking tubing must prevent loose 230 V cables from getting in contact with ELV cables—supply or signal cables—and vice versa.
4.It must be simple to break the power supply for the controller or for the complete installation.
5.When several Xenta controllers are supplied from a common transformer, it is important that all G’s are connected with each other and that all G0’s are connected with each other. They must not be interchanged. An important exception: G0 on the wall module should not be connected with the other G0’s. Instead it should be connected to the terminal OP on the controller. At the transformer, G0 should be connected to protective earth. This is to get an grounding point for interference diversion.
6.Connect the two M terminals to the wall module to get the specified measuring accuracy for the room temperature.
Safety standard
Transformers supplying the controller must comply to the safety standard EN 60 742 or any other relevant safety standard for ELV, 24 V AC. When equipment with a power supply of its own is connected, e.g. an occupancy sensor, this power supply must also comply with this norm.
Cable lengths
For information on communication cable lengths, see TAC Xenta Network Guide, part number 0-004-7460. For all other cables, maximum length is 30 m and min. area is 0,7 mm2 .
Wall modules ZS 101–ZS 104
It is mainly the wall modules ZS 101–ZS 104 which are intended for use together with TAC Xenta 102. The wall module ZS 105 can also be used, but then the fan switch on this unit is not used. The wiring diagrams on the following pages show how wiring with ZS 104 should be done, as this is the model that has all connections.
