1. Presentation of the system
The C7000 control system offers a maximum of operating safety for industrial applications combined with two versions for the operator interface. The C7000IOC takes charge of the control in itself and the optional C7000
Advanced serves as a comfortable operator interface.
Distributed intelligence in networking cells represents the most reliable system whenever operating safety is the target. This is exactly how the Stulz C7000 control system works, each A/C unit possesses its own controller while all controllers can be linked together in a bus system.
This way a natural redundancy is obtained which assures the system functions with the least expense. And we locate the intelligence there where it is needed, in the A/C unit without long cables which could mess up the signals.
Whereas the C7000 Advanced provides the well known operating comfort - as did already the C6000 - the
C7000IOC can bring to bear his advantages when it comes to modifications in the configuration of a large air conditioning system with several units.
The idea of the second interface was to use a device which is present everywhere, a computer. Using the screen of a Laptop or PC provides the best way of visualizing parameter settings. This is the most comfortable way of doing a component-related configuration.
Beyond the basic air conditioning functions, the C7000 control system provides some interesting features like an intelligent management of high/low pressure-alarms, a proportional fan speed control which opens a wide spectrum of applications and time-based functions like:
- week timer
- unit sequencing within definable unit groups
The heart of the C7000 control system is the C7000 I/O controller on which up to 4 EAIO/EDIO boards for additional in- and outputs can be perpendicularly plugged.
The exploitation of the third dimension provides maximum accessibility and an easy board exchange in case of modifications.
The C7000 control systems manages 3 busses:
1. IIC-bus for the communication between the C7000
I/O controller and the EAIO/EDIO boards
2. RS485 IO-bus for the communication among the
A/C units
3. RS485 BMS-bus for the communication with a building management system
For service purposes like software download and control via laptop a RS232 interface is located on the I/O controller the same as on the C7000 Advanced.

The EAIO-board is an extension board for analogous inputs and outputs. It can be plugged on the I/O controller board at each of the 4 sockets and will be recognized by the IOC due to a self test.
There are several jumpers on board - 5 for each input - which serve to adapt the board to different sensor types.
How to use the Jumper setting table:
- choose the analogous input at which you have connected a sensor.
- in the same line you can see the jumpers which relate to this input.
- in the lower part of the table you can read in each column the setting depending on the sensor type you connected.
Example:
You have connected a 0-10V sensor at AIN 8.
The corresponding jumpers are 300-304. Jumper
301,303,304 must be set on position 1-2, Jumper
302 on 2-3 and Jumper 300 not at all.

2.7 Driver module
The driver module has the following features:
1. a static bus termination (120 Ohm), which can be activated by a jumper.
2. a circuit to set the bias for the bus. By means of two jumpers either a low bias (bus middle) or a high bias (bus end) can be set.
3. protection against electrostatic discharge (ESD) impulses on the data lines
The interference immunity of the bus is increased by the driver module.
As far as the jumper settings are concerned, only the two settings shown below are allowed. The jumpers must be changed blockwise. Other settings result in an unstable bus communication.
Participant at the end of the RS485 bus
This figure shows the jumper position for the participant at the end of the bus.
The rightmost jumper is located in a position where the termination resistor is activated.
The other jumpers are set for a high bias.

3. Operator interface
3.1 Operational elements - C7000 IOC
The operational elements for the C7000 IOC i.e. the I/O controller consist of the keyboard of your PC or laptop.
You operate the C7000 IOC by specified commands which follow an easily comprehensible syntax.
To establish the connection from your PC to the C7000 you need a 9-line cable with SUB-D 9 connectors at both ends (crossed type), which can be obtained as an option and a terminal program e.g "C7000-Serice".
Connect the cable at a serial port of your PC and at the service port X15 on the IOC. when connecting the laptop to the IOC service port.
Start the terminal program.
If your PC is not equipped with a serial RS232 interface, you may use a RS232-USB converter.
You can now communicate with the connected I/O controller (ioc), in return the IOC sends the following prompt to your PC:
" ioc ##:>", where ## represents the bus address.
To prevent a destruction of electronical elements due to potential differences, use a laptop with battery supply
The commands can be classified into three major categories:
1. bus specific control commands
2. commands related to A/C unit components
3. commands concerning the whole A/C unit
1. bus command iobus iobusok
2. component command sensor 1 comp 1 suctionv 1 gecwv gvalve drycool 1 pump 1 eheat 1 gasheat pwwheat humi 1 dehumi fan 1 louver 1
3. A/C unit command equip is 1 state ups wprg event log 1 option exalarmin 1 zone 1 loaddefault dx1
The commands on a lightgrey (yellow) background need no further parameters. The commands which are followed by a number need this number because there are several components of the same type.
Each command displays a detailed help for further parameters (if there are any) when it is followed by "h" like e.g. "comp h".
A command of the second (component command) or third category (A/C unit comm.) which is typed in without any parameters displays all the information about its subject (except "loaddefault ###" which is an execution command).
The commands of the 2nd and 3rd category will be largely explained in the context of the description of the
C7000 functions.
The iobus command edits the actually stored IO-busconfiguration.
This command is a control command and shows neither help nor information but execute the command right after pressing the return/enter-key.
E/0409/ 57/18
General
The counting of any digital or analogous in- or output begins with number 1. Despite this the digital/analogous in- or output 0 can be assigned to any component. This will allow the component to stay part of the configuration even if it does not take part in the control.
A double assignment of inputs and outputs is technically possible but only reasonable in exceptional cases.
Outputs in the languages English and German are available at the service interface.
If within a command, where the input of a number is expected, nothing is entered, the terminal program interprets this as "0" (command "coolingprio" is interpreted as "coolingprio 0").
Whenever a parameter is expressed by a logical function,
0 means no, disabled, 1 means yes, enabled.
If at unit start no valid configuration is found, a minimal configuration for single refrigerant circuit-units is loaded.
Please note that no year date below 2000 can be entered.

Operation - Navigation through the menus
The principal keys to navigate in and across the menus are the selector key and the confirmation key, which have the function of the mouse for a PC.
The cursor, to keep the analogy with a PC, is represented by the inverse display of a field content. This field may contain an expression, a number or a symbol.
There are two types of menus: Selection menus and parameter menus. In
selection menus you can choose a menu point with the help of the selector key and after having pressed the confirmation key it will bring you to the next submenu. To get to the next menu on a level above there is a "Return"-field in the top left corner of every menu.
In parameter menus, which represent the end of a menu branch, you can select parameters with the selector key, but if you press the confirmation key, the parameter is displayed black on a clear background with a black frame and indicates this way the change mode. By the selector key you can change the parameter value. Pressing the confirmation key finishes the modification and displays the cursor inversely again.
In a few parameter menus, there is the comment "more" in the bottom frame line, which indicates that another window will be displayed after the last parameter. You can also reach this window by typing the selector key "<" when the cursor is on the field "return".
Note:
After the C7000AT has displayed a submenu of an IOC for 10 minutes without key activation, it will show the main menu of the corresponding unit again.

If you select the C7000 AT for further adjustments and confirm with OK you will receive after having entered the password 2718 the following display with the menu ramification as shown below:
1. In the bms-menu you can adjust the global address of the C7000 AT, and an available interface on the C7000AT which can be either RS232 or
RS485 the same as the protocol and, if applicable, one of several data point lists according to the BMS requirement.
You have further possibilities to adapt the system to the BMS by the menu points „Handshake“ and „Baudrate“. For further information, see
BMS manual.
2. Here you can set the alarm delay for the bus alarm, which will be generated when the bus is interrupted.
3. In the system menu you can switch on (-1-) or off the alarm buzzer.
Further you can adjust the buzzer pitch.
Menu item "Temp. unit" allows you to choose between degree Fahrenheit or degree Celsius.
In the menu item languages you can adjust the operator language.
The info submenu simply displays the software version of the C7000 AT.
In menu item "backlight" you can choose between "on" (in this case the light remains lit permanently) and "auto", here the light is switched out automatically 10 minutes after the last key activation. With the first key activation the light is switched on again.

Instead of numerical values two other displays are possible:
1. ??? - value requested at the IOC, without response yet
2. XXX - component not configured
Symbols for alarm messages
When an alarm has occurred the following symbol is displayed in the left bottom corner.
Passwords
To access the Operate level and the Config level a password is required.
There are 4 passwords in total, a user-specific password for the Operate and Config level each and a master password for each level.
The user-specific password can be modified and is "0000" for both levels with the delivery.
The master passwords are reserved for service staff and can not be modified.
Entering the password
The digits can be modified by the selector key, after you have pressed the confirmation key. After the digit adjustment confirm with the confirmation key and pass over to the next digit with the selector key ">".
When you have reached the last digit at the right, you access the main menu of the Operate resp. Config level by activating the selector key
">" (if the password was right).
There is no limitation for the number of attempts.
The passwords for the "operate" and "config" level are saved on the IOC board. So it is possible for example to adjust the "operate" password "1234" for an IOC with bus address
3 and the "operate" password "5678" for an
IOC with bus address 5.

5.3 Bus Layout
5.3.1 General
The IO bus consists of maximum 20 participants. In case of the C7000 system only C7000 IOC or C7000 AT bus participants can be in the IO bus.
Each bus participant has its own IO bus address which must only appear once in the data bus.
The IO bus addresses range from 0 to 19.
The display of the C7000 AT shows the IO bus addresses in a bus overview (start window) as follows:
5.3.2 Configuration of the IO bus
The configuration of the bus is done automatically during start-up and operation. That means that all connected bus participants log on automatically. The same applies in case of a failure - all bus participants are logged off automatically.
Following preconditions must be fulfilled:
1. Each bus participant has its own bus address which must be unique in the bus system.
2. Bus addresses must range between 0 and 19.
3. All bus participants are connected appropriately with bus cables according to requirements (see next page).
4. The bus has to be terminated at the beginning and at the end.
Each bus participant saves the latest registered configuration during shut-down. Furthermore the bus participant expects the same configuration after its next start-up.
In case new systems have logged on to the bus during the shut-down period, the bus participant detects these systems and records them in the bus configuration without editing a message or an alarm.
In case a system has been disconnected from the bus which was active before shut-down, the bus participant detects this condition and a bus error is triggered in the bus participant after the end of the alarm delay.
The same happens when a bus participant (IOC or C7000AT) is de-energized during operation.
All systems that are connected to the bus detect a bus error automatically. Accordingly this error is displayed on the AT and IOC.
E/0409/ 57/27
5.3.3 Preparation before Installation
You need a shielded cable with two lines twisted and a cable impedance of 120
Ω (Recommendation Belden 9841), which you have to connect from unit to unit at the terminals
56-59 of each I/O controller (IOC). In the example below the bus termination of the two units which form the end of the bus (IOC 01 and IOC 17) must be enabled.
The example of a RS485 bus shows a typical application with 7 IOCs and 1 C7000 AT.

5.3.4 Setting the Bus Address
The bus address is adjusted with the dip-switches on the IOC. The table at the right shows the corresponding adjustment for all possible bus addresses. Please note that the counting begins with 0 and ends with 19. A "1" means dip-switch in "ON"-position.
If you set an address higher than 19, this one is reduced to 19 by the software.
An IOC is delivered with the address 1 as standard, a C7000 AT has the address 0 as standard.
On a C7000 AT the bus address is adjusted in the placement view.

Placement view
in short:
1. connect units by bus lines
2. set bus terminations (beginning/end)
3. adjust bus-IDs
4. confirm bus configuration
With the selector key you can shift the C7000 AT represented by symbol "ME" to a new position and change its bus address this way.
Left display: old position address 0, new position address 17.
To confirm the selection press the OK key.
Now the bus configuration must be confirmed to avoid the display of a bus error, because a bus participant with the address 0 does not exist anymore.
The addresses of all other participants are not affected by this.
How to get to the placement view and how to confirm the configuration, see chapter 4, page 21.

figured unit is 0%, an error is indicated.
The AT 19 detects, that the IOC 6 has been available in the bus, but can not be reached anymore. When the disconnected unit is switched on again, the bus error is automatically deleted at all bus participants. A bus error can also be deleted by inputting the command " iobusok" at an IOC or an AT.
E/0409/ 57/29
There is another way to delete a bus error on the AT and to transfer so the actual bus configuration.
For this purpose all systems have to be selected simultaneously and afterwards the OK-button has to be pressed.
After entering the password (2718) the faulty unit (address 6) is deleted from the bus. The bus error disappears.
5.3.6 Special cases
Disconnecting a bus
An important aspect concerning the display of the IO bus is that the display is always exclusively dependent on the C7000AT which is in use at the moment.
For example a bus disconnection between the bus participants 4, 5, 6, 7, 16, 17 and the bus participants 18, 19 results in two completely independently running busses.
However the bus participants 4, 5, 6, 7, 16, 17 report the bus participants 18, 19 as faulty and vice versa.

The bus error has an adjustable alarm delay. Once this delay has expired the bus error is triggered. This delay is separately adjustable for each bus participant.
Address conflict
The second failure concerning the bus is a conflict in the address. A conflict in the address occurs when two or more bus participants have the same bus address.
That means that the two bus participants which have the same address send simultaneously data to the bus. This on the other hand would destroy the data on the bus.
Communications via the bus would be limited.
But this does not happen because bus participants stop the data transfer immediately as soon as they detect that another participant with the same address is sending a data package.
That means that they stop sending and hence do not participate in the communication on the bus anymore.
An address conflict is triggered immediately as soon as a unit has performed a deactivation.
In our example two ATs have the bus address 19.
As soon as the communication on the bus starts, one of them detects that the address 19 has been assigned twice and performs a deactivation.
The result is that only one bus participant with the same address is active after a short time.

The user is requested to choose another bus address at the C7000AT which has detected the address conflict.

BUS ADDRESS CONFLICT AT ADRESS ‚ME‘ = 19 DETECTED.
If an address conflict exists, this one is indicated for the corresponding bus participant.
The other AT with the bus address 19 continues operation without any interference.
After the bus address has been assigned properly the address conflict will be solved automatically.
An address conflict can only be displayed at the unit, which causes the address conflict, because it excludes itself immediately from bus communication. If this unit is a C7000AT, this is displayed on the display. An address conflict can only be displayed at unit "ME".
If the unit is a C7000IOC the error LED on the board flashes, the state of the bus configuration can then be requested by using the service port.

6.1.2 Overview structure
Due to the complexity of the menu ramification, it was impossible to display entire menu branches on one page.
We therefore applicated a city map screen on the menu overview, consisting of columns and rows which serve to easily relocate single submenus within the overview.
Each page features a capital letter and is subdivided in three columns.
The Info menu runs from page A to E.
The Operate menu runs from page F to J.
The Config menu runs from page K to S.
The top row, in which the top menu (Info, Operate or
Config) is placed, has no line identification. The rows below for the submenus are named from "a" to "f".
There are up to 4 submenu levels.The first two submenu levels are horizontally located. The third submenu level is vertically located. The fourth submenu level is marked by a grey background.
On the pages which follow the overview, only the parameter menus are explained, these are normally the menus of the lowest submenu level.

Values
The first item of the menu concerns the adjustment of temperature setpoints.The following items serve to adjust the temperature limits, which are decisive for the alarms "temperature/humidity too high/low".
Two temperature setpoints can be adjusted, setpoint 1 concerns the operation by day, whereas setpoint 2 concerns operation at night according to the week timer
(page 78).
Following the limit values for the room air sensor. The "MIN" column contains the values for the lower temperature limit and the "MAX" column relates to the upper limits accordingly.
If e.g. the minimum room air temperature is passed under by the measured value, the alarm "Room temperature too low" is displayed.
In the line below you can set the alarm delay in seconds.
The values for the supply air sensor can be adjusted in the same way.
F1d
You can set the same parameters for the air humidity. However no difference between day- and night setpoint is made.
Here you can input a setpoint for the raised floor pressure. If this value is different from zero, the raised floor pressure control will begin. See chapter 7, special functions.
F1e
F2b
You can set alarm delays and limit values for the water temperature. When the limit values are exceeded, the alarms "Water temperature too low/high" are released.
For the operation of pump stations you can set a pressure setpoint. The pressure setpoint represents the pressure increase by the pumps.
When the C7000 is used to control a pump station, the water pressure is the only parameter which is controlled. This mode represents a special function of the C7000.
F3b
Here you can input a setpoint for the condensation pressure of the refrigerant. The
G valve is controlled according to this setpoint.
For the DX-mode and the mixmode in case of proportional GE control individual values can be set. The setpoint for mixmode should be smaller than for DX mode to discharge the compressor. This way free cooling by the water coil has a greater part in total cooling.
For normal GE control only the DX value is operative.

After the compressor start the low pressure alarm can be inhibited for an adjustable time ➎ b. If the unit is equipped with two compressors, the adjusted time is valid for both compressors (1 and 2). This time avoids a low pressure alarm right after the compressor start when outside temperatures are low. The effect of this parameter does not depend on the summer/winter operation.
Compressor sequencing in units with two refrigerant circuits:
The controller software tries to equilibrate the compressor runtimes. Once in an hour the software checks whether the difference between the runtimes is 20 hours or more.
If this is the case and if the compressor with the bigger runtime has a smaller start value than the other compressor, the start values and hysteresises for summer and winter operation are exchanged between the compressors.

The bullet items within the text refer to the corresponding command at the bottom of the page.

ECO Louver
Operate
This function enables a "Free cooling" with outside air, which is directed by a louver system. Three louvers are necessary, which will be controlled in parallel by a single analogous output.
- Fresh air louver for the inlet of fresh outside air
- Circulating air louver for the circulation of the room air
- Exhaust air louver for the outlet of warm room air
The fresh air and exhaust air louver are operated in parallel, the circulating air louver is operated in a reverse sense to these louvers. The setting is done by determinating the sense of rotation at the louver actuators.
Free cooling is enabled, when:
1. room humidity is within determined limits (see diagram) and
2. outside air is cold enough. This means when the temperature of outside air is below the EcoCool start value
➊
.
Free cooling is stopped, when the outside temperature is above the EcoCool start temperature ➊ + hysteresis ➋ or when the room air humidity is outside the limits.
The start temperature ➌ for the control must be entered as a positive difference to the air temperature setpoint. In the fourth line you can set the gradient

Dehumidification (Part 2)
There four ways of realizing a dehumidification:
1. by reducing the fan speed and CW valve operation, this is the only way of dehumidification for CW-units.
2. by shutting down a part of the evaporator via a solenoid valve. (not for CyberAir 2 units)
3. by the electric expansion valve (only in CyberAir 2 units)
4. by reducing the fan speed and compressor operation.
The choice of the dehumidification type is made by the controller according to the following conditions: The priority lies on reducing the fan speed. This is the case for ACW/GCW/GEunits in mixed operation. Only if the compressor is actually in operation and if a dehumidification valve is present, the 2nd way of dehumidification is chosen. The two dehumidifying ways are never applicated simultaneously.
If no dehumidification valve is present as in units of the series
CyberAir 2, dehumidification is carried out by the electric expansion valve. If this is insufficient, the fan speed is reduced additionally after a time delay.
The decision procedures of the controller are displayed in detail in the scheme below.

With the room control with supply air limitation the control takes place via the
T/H sensor in the return air intake and via a second T/H sensor in the supply air. Primarily the control takes place as for room air control, only if the measured supply air temperature exceeds the start temperature ➋ as a gradient
the temperature setpoint is shifted. The extent of the setpoint increase is determined by a factor which you enter,
➌
, in the menu.
The relationship, according to which this happens, is made clear by the graph opposite. A steep gradient drastically corrects the failure to meet the supply air temperature, but has the risk that the control circuit starts to oscillate.
With humidity control the setpoint shift takes place in the opposite direction. If the adjusted starting humidity ➍ is exceeded by the measured supply air humidity, the setpoint is reduced. You can also enter a gradient factor ➎ for this. The relationship is shown in the graph opposite.

This parameter is relevant only for the proportional GE control. For this a separate manual exists.
Additionally you can prevent mixed operation of Freecooling and compressor cooling by setting the "Close at comp" value ➐ to "1". (see graphic below).
In the third line you can adjust, whether the valve shall close as soon as the water temperature exceeds the air temperature setpoint

Setting 0: Valve closed at 0V at the output, valve open at 10V at the output.
➒ . The control characteristics will be changed by this setting. When the air temperature falls the valve opens, a rising air temperature will close the valve gradually.
In the fifth line you can adjust, how the valve will be controlled
Setting 1: Valve closed at 10V at the output, valve open at 0V at the output.
In the sixth line you can set a time delay which must pass until the control of the
GE/CW valve begins and the water limit alarms are monitored. Until this time has elapsed, the valve is fully (100%) opened.
The parameter in the seventh line is only important for CW2 units.
Here you can set an opening degree for the CW valve of the first water circuit. This opening degree is kept by the valve while the cooling is produced by water circuit
2. By this, a minimum water flow is guaranteed in circuit 1, which is necessary to measure the water temperature. With a sufficiently low water temperature the cooling production can be switched back to circuit 1. Without a cooling request in circuit 1 the valve is completely closed.

For this you adjust a positive temperature difference represents the start point of the speed increase.
Then you adjust a maximum speed ➑
➑ a to the setpoint, which

Having attained the second temperature difference, the fan is operated with the maximum speed for the overload operation.This speed is kept even if the temperature continues to rise.

The fan speed nmaxDX or nmaxCW is chosen according to the cooling priority and the conditions for a malfunction change-over. (details for the cooling priority, see page 77 )
Then 4 queries are passed, which entail a speed reduction or increase. Finally the algorithm checks whether the minimum speed is kept and whether the conditions for the REDUCE SPEED are kept, which can bypass the minimum speed as the sole reduction.

Manual Operation
When manual operation is used the C7000 control is put out of force.
The manual operation menu consists of two columns of parameters which are decisive for the operation.
In the first column (titled EN.) you enable the manual operation of the listed component by setting the parameter to "1".
➋
➊
The second column (titled STATE) displays the actual state of the component.
After you have enabled the man. op. in the first column, you can switch on/off the component itself.
For proportionally controlled components you can enter a percentage in the second column (titled VALUE) which corresponds to an opening degree for a valve or a capacity for any other component.
Components which exist either with on/off control or with proportional control have both columns (STATE and VALUE). But only the corresponding parameter comes into effect.
Sensors and external alarms can be simulated by the manual operation for the purpose of testing the controller function.
When the manual operation menu is left (e.g. when the menu "components" is reached again), the manual operation of each component is disabled and the controller takes over the control again.
When the fan is switched off, any other component is electrically blocked and can not be started.
If the unit is de-energized, all manual settings are reset.
However, the adjusted proportional values are kept.

7. Special functions
7.1 Raised floor pressure control
N1c
The pre-condition for this control is that every A/C unit is equipped with a pressure sensor.
The option for a raised floor pressure sensor provided by Stulz features a pressure range of 0-100 Pa or 0-250 Pa which is adjustable by jumpers. The output signal can be adjusted to 0-10 V or 4-20 mA. This sensor must be calibrated in the menu N1c.
The raised floor pressure control is enabled by a value in menu F1e which is different from zero.
The control tries to keep the adjusted setpoint for the surpressure in the raised floor. The air temperature control is continued but the pressure control has priority to the temperature control.
F1e
M3c
For this control a proportionally controlled fan with an analogous output has to be configured (Setting: LINEAR).
The control begins after the lapse of the "START 100%" time and the prerun time ( M3e) with the maximum speed (max. DX or max. CW according to the adjusted cooling priority). An offset value, which serves to adapt the air volume flow to local conditions will not be considered.
Maximum speed serves only as an initial value for the control which starts now by measuring the difference to the air pressure setpoint and reduces the fan speed in case of exceeding the setpoint and increases fan speed when the setpoint is passed under.
By three parameters (cycle, maximum control modification and control factor) the characteristics of an integral control are achieved.
The adjusted minimum speeds are not passed under during control.
All speed increases or reductions for the fan with the exception of "reduction according to time" (parameter called REDUCE SPEED) are put out of force. If during the time adjusted here none of the functions "cooling, heating, humidification, dehumidification" is requested, the speed is reduced by the percentage, which you have adjusted in the 2nd column of "REDUCE SPEED".
M3e
After the unit stop the fan runs during an overrun time, which serves to reject hot or cold air in the unit.
The menu items, which are irrelevant for the raised floor pressure control have a grey backgroung.
E/0409/ 57/101
In the menus H3c and M3d you can configure the alarms "air flow alarm" and "filter alarm" with all corresponding parameters.

7.2 Changeover of the water circuits - CW2 units
In the menu L3c you can choose between two operating modes:
1. Changeover operation (Parameter "Mode" : Separate)
2. Additional operation (Parameter "Mode" : Addedt)
Changeover operation
For changeover operation only the parameter settings for CW valve 1 (menu
G3e) are relevant (start temperature and gradient). In case of a changeover these settings are applied on the active valve. The passive valve is completely closed if it treats of valve 2. If the passive valve is valve 1 in the first water circuit, it will be closed to the "value at switching". So to speak the output
A-OUT for valve 01 is commuted on A-OUT for valve 02 (or A-OUT 02 on
A-OUT 01).
L3c
If one or several of the following conditions are met, the output is commuted from A-OUT 01 to A-OUT 02:
1. A voltage is present at the digital input (menu L3c, parameter D-IN), which was assigned to the GE/CW valve.
2. DP 1025 is written with value "1" by a BMS.
3. DP 1025 is written with value "1" by inputting "1" for the parameter "CW2changeover" in menu K2b.
4. Water temperature in circuit 1 is higher than parameter "GE-off" (menu
G3e).
5. Water temperature in circuit 1 is higher than the air temperature setpoint, in case the parameter "Close, if water above SP" (menu L3c) has been set
"1".
G3e
If none of the above listed conditions is true, the output is switched back from
A-OUT 02 to A-OUT 01.
K2b
The changeover is displayed by the parameter "State" in the menu K2b of the Config level and is output by a freely adjustable digital output (menu L3c, parameter D-OUT).
If a dehumidification request exists, the active valve will be opened 100% to provide maximum cooling capacity for dehumidification.
E/0409/ 57/102
Additional operation
During additional operation both CW valves can be open simultaneously. Start temperature 1 and gradient 1 apply to CW valve 1, start temperature 2 and gradient 2 apply to CW valve 2 (menu G3e). A commutation is possible also during additional operation. This is done by an exchange of start temperatures and gradients between both valves.
If one or several of the following conditions are met, the parameters of both valves are exchanged:
1. A voltage is present at the digital input (menu L3c, parameter D-IN), which was assigned to the GE/CW valve.
2. DP 1025 is written with value "1" by a BMS.
3. DP 1025 is written with value "1" by inputting "1" for the parameter "CW2-changeover" in menu K2b.
4. Water temperature in circuit 1 is higher than parameter "GE-off" (menu G3e). Valve 1 will be closed to the "value at switching" in this case.
5. Water temperature in circuit 1 is higher than the air temperature setpoint, in case the parameter "Close, if water above SP" (menu L3c) has been set "1". Valve 1 will be closed to the "value at switching" in this case.
Attention: If condition 4 or 5 applies to valve 2, this valve is completely closed.
If none of the above listed conditions is true, the parameters of both valves are changed back.
The changeover is displayed by the parameter "State" in the menu K2b of the Config level and is output by a freely adjustable digital output (menu L3c, parameter D-OUT).
If a dehumidification request and no condition for a parameter exchange exists, valve 1 is opened 100% to provide maximum cooling capacity for dehumidification.
If a dehumidification request and a condition for a parameter exchange exist, valve 2 is opened 100%

7.3 Zone control
The zone concept is based on the idea to obtain a homogeneous room climate within a determined space by distributed generation of conditionned air.
Within an IO bus up to 20 zones can be defined. A zone is defined if at least one unit is assigned to this zone. The assignment of a unit to a zone is done by setting a zone number in the main line of menu Q1a.
This assignment must be done individually for each unit (each IOC).
Q1a
Average value determination
A basic principle of the zone control is the calculation of average values of the measured values. Within a zone only one room temperature exists which is calculated as the average value of all connected room temperature sensors.
The same applies for the room humidity, supply temperature, supply humidity, outside air temperature, water inlet temperature 1, water pressure and raised floor pressure, if existant.
The determination of average values can be disabled by the parameter in the sixth line of menu
Q1a (0 = off, 1 = on). By the parameter in the seventh line of the same menu you can set whether standby units shall take part in the calculation of average values. (0 = no, 1 = yes).
J1a
However the set values can be individually adjusted for each unit. If at all they should only slightly vary.
Q2a
Standby units
In the menus
J1a and Q2a you can put the unit in standby by setting the parameter in the third line "1".
The existence of standby units in a zone increase the airconditioning operating security and provides the possibility to replace defective units by standby units.
Alarm changeover
In order to changeover units in the event of an alarm, you can define alarms as valid by setting the corresponding parameter „1“ in the menus
Q2b, Q2c,
Q2d and Q2e. If such an alarm (defined as valid) occurs, the defective unit is switched off and the standby unit with the next higher bus address is switched on. If another unit with a valid alarm occurs in the zone, the next standby unit (if existant) is switched on.
Some alarms cause the cut-off of the defective unit or the deactivation of functions even if the alarm has not been defined valid. (for details see chapter
8.1 alarm messages).
The alarm „unit not available“ can not be deleted from the alarm list. This alarm is always part of the valid alarms and appears in case of a bus failure or when the unit has been de-energized.

Q2d
Q2e
Emergency operation
With the parameter in the second line of menu
Q1a you can enable an emergency operation. If this parameter is set "0", emergency operation is disabled. By this parameter you set the number of defective units which are necessary to enable emergency operation.
Emergency operation means that each A/C unit of the IO bus applies the zone-specific emergency temperature as new temperature set value. The emergency temperature is set for each zone with the parameter in the third line of menu
Q1a.
Function of standby units
Even if the failing unit capacity of one zone is completely equalled by the start of standby units, the defective units are counted as lacking.
To start an emergency operation just when the 100% unit capacity (without standby units) is not reached anymore, the adjusted number of defective units should be higher than the number of a zone's standby units.
Q1a
K1d
Additional capacity - Temperature
You can have started a standby unit if the air temperature setpoint is exceeded by the zone temperature (Average value or unit temperature, when average value determination is disabled).
The excess of the setpoint can be adjusted by the parameter in the third line of menu K1d in the shape of a temperature difference. Setting "0" disables the additional capacity function.
When the temperature sinks again, the additional capacity unit is switched off with a hysteresis of 1K.
Additional capacity - Humidity
You can have started a standby unit if the air humidity setpoint is passed under by the zone humidity (Average value or unit humidity, when average value determination is disabled).
The undercut of the setpoint can be adjusted by the parameter in the third line of menu K1e in the shape of a humidity difference. Setting "0" disables the additional capacity function.
When the humidity rises again, the additional capacity unit is switched off with a hysteresis of 3% relative humidity.
Precondition:
The additional capacity unit must be set as standby unit and must be assigned to a zone. Moreover the corresponding parameter (temperature or humidity) "Overload" must have a value different from zero.
K1e
E/0409/ 57/105
The zone control comprises three specific functions:
1. Sequencing,
2. CW Standby Management,
3. Zone for proportional GE control
Q1a
7.3.1 Sequencing
The sequencing provides a time dependent unit changeover. By the use of standby units, a high operating reliability the same as an even unit exploitation is achieved.
By setting the cycle time (parameter in the first line of menu Q1a) you adjust the lapse of time, after which a changeover is done periodically. This means that the standby status is changed over the units one by one. With the setting 0 (hrs) no sequencing is made.
Failure dependent change-over
Setting the cycletime causes the sequencing start.
Zone 02
Enabling the test sequencing (parameter in the fifth line of menu Q1a) with the fixed cycletime of 5 minutes helps you to check the sequencing function.
All basic zone functions which have been described on the previous pages are also available when the sequencing is enabled. a. Average value determination or deactivation b. Alarm changeover c. Emergency operation d. Additional capacity
Time dependent change-over
(normal sequencing) e. g. with 2 standby units:
1. cycle unit 07, 11 standby
2. cycle unit 08, 14 standby
3. cycle unit 11, 01 standby etc.
Zone 01
Unit 01 Unit 03

The sequencing runs independently from an additional capacity function and independently from defective units.
Even a defective unit can be set standby by the sequencing. Only when the unit has to be switched on due to the changeover, the control detects that the unit is defective and the unit remains switched off. Then the standby unit with the next higher bus address is switched on.
The unit, which is provided as additional capacity, can only be switched on during the cycles, in which it is in standby.

7.3.2 CW Standby Management
The CW standby management can be carried out with CW units and Dualfluid units with CW cooling priority. The basic idea is to share the heat load permanently with as many as possible units in order to reduce the fan speed of all units and thus to save energy. For this the provided standby units must constantly take part in the cooling process. The total airflow is below the airflow which is possible at most and is equalled in case of failure of one or more units by increasing the fanspeed of the remaining units.
By "MAXFANSPEED" you adjust the fan speed which is to be kept in the zone when all units are running. By "CW-ENERGY-SAVE" the CW-standby management is enabled and in the same moment all standby units of the zone are switched on. Both parameters are related to the zone and have only to be adjusted at one unit of the zone.
The table beside displays how many units in a zone are necessary to keep the total airflow at the indicated fan speed in the left column, when "f" units have failed.
This correlation is represented by the following formula.

An A/C unit is switched off as defective unit if a valid alarm occurs at this unit, in the same way as for the sequencing.
When a Dualfluid unit changes over to DX operation due to a fault like a "water temperature too high" alarm , this unit applies the nMaxDX fan speed which is higher than the MAXFANSPEED of the CW standby management.
The fan speed of the other units is not affected by this.
7.3.3 Zone for proportional GE control
Such a zone consists of GE type A/C units, drycoolers and external glycol pumps. Concerning the hardware, the zone exists in the shape of a common cooling water circuit and a common control of drycoolers and external glycol pumps.
On the software level the zone operation is carried out by assigning the
A/C unit to the same zone and by setting the parameters "start temperature, hysteresis" or "water start temperature (=water inlet temperature 1), hysteresis" different from "0". By this setting the proportional GE control is activated. The zone parameters are transmitted to all units/controllers of the zone and are assumed by these.
Some parameters as sequencing cycle and standby state are only operative in DX mode. The proportional GE control is described in detail in a separate manual.
Q2a
E/0409/ 57/107
7.4 Free cooling with ECO-Cool Louver
This function enables a "Free cooling" with outside air, which is directed by a louver system. Three louvers are necessary, which will be controlled in parallel by a single analogous output.
L2b
1. Fresh air louver for the inlet of fresh outside air
2. Circulating air louver for the circulation of the room air
3. Exhaust air louver for the outlet of warm room air
The fresh air and exhaust air louver are operated in parallel, the circulating air louver is operated in a reverse sense to these louvers. The setting is done by determinating the sense of rotation at the louver actuators.
G2b
Configuration
By setting the parameter "ACTIVE" on 1 you add an ECO louver to the configuration.
With "0" you disable the ECO-louver.
With the parameter "A-OUT" you determine a analogous output for the louver.
Control
Free cooling is enabled, when:
- room humidity is within determined limits (see diagram) and
- outside air is cold enough. This means when the temperature of outside air is below the EcoCool start value
Free cooling is stopped, when the outside temperature is above the EcoCool start temperature ➊
➊
+ hysteresis
.
➋ or when the room air humidity is outside the limits.
The start temperature ➌ for the control must be entered as a positive difference to the air temperature setpoint. In the fourth line you can set the gradient ➍ , which defines the range, in which the fresh air and exhaust air louver opens from 0 to 100% and the circulating air louver closes in the same way.
Additionally to normal operation there exist an emergency operation. If no compressor is in the condition to operate, the free cooling by EcoCool louvers is enabled independently of the limits of air humidity and air temperature.

7.5 Pump station control
The concept of pump station control is based upon the idea that one pump station provides the water conveyance for up to five units, which need water for cooling.
Due to the differing need of cooling water the water pressure in the system is exposed to big variations. This control assures that the water pressure at the unit outlet is kept constant by pump speed control.
The pump station control represents a special control in the C7000 and can be set in menu S1b by the pre-configuration "PS". The corresponding command via the
IOC service port is:
" loaddefault ps
"
S1b
PS
If the pump station is equipped with a C7000AT, the actual value of the water pressure at the unit outlet and optionally the water temperature is displayed in the main menu of this controller.
In the bus overview the pump station is displayed by a symbol, which contains the values of these two parameters.
The units, which are provided with water and the pump station itself form a zone, which must be defined at the controller of the pump station.
Attention:
The pump station zone represents a special zone which must not be confused with the zone operation, which you can set in menu Q1a.
This means, that an A/C unit can belong to a pump station zone and can be part of another (sequencing) zone simultaneously.
Temperature
Pressure
The single units must be assigned to this zone at the pump station controller by means of their bus addresses. At the C7000AT you can do this by setting the parameters for the units "1“. In menu
K2d of the Config level the possible units of the IO-bus are displayed in four lines. The units with the bus addresses from 0 to 4 are displayed in the first line by placeholders "-0-“. The other units are displayed in the following three lines corrspondingly. By setting the parameter "0“, the corresponding controller is taken out of the pump station zone.
K2d
Assigning units to a pump station zone is done in the C7000IOC of the pump station by the command: pszone + 3
By the following command the unit with the address 3 is taken out of the pump station zone.
pszone - 3
When a unit sends a cooling water request on the IO bus, the pump station controller verifies whether this unit is part of its pump station zone and starts pump operation if the result is positive.
Cut off by error:
In case of an alarm of the flow monitor or a failure of all configured pumps the pump station is switched off.
With the application of a pump station you do not have to configure pumps in the
GE units.

Each pump station contains two pumps. In normal operation both pumps run at low speed. In case of a pump failure the speed of the remaining trouble-free pump is increased.
However, you can adjust a standby operation.
Standby operation can be enabled in the shape of a sequencing based on time and failure. With "partner pump"

10. Configuration notes
First steps after the reception of a new software
1. Load software on IOC, resp. on C7000AT. (see 10.1 Loading a new software)
2. Check bus configuration (configuration is kept after loading the software)
3. Load a default configuration according to the unit type (see 8.1 pre-configurations)
4. Check the equipment by command "equip".
5. Configure additional components.
At the C7000AT you can do this in the Config-level in the submenus of the menu point "Components". Part of the configuration is the activation of the component, the allocation of an output for the component control and eventually the assignment of an alarm input.

10.1 Loading a new Software
For a C7000-control system there are two different softwares. The essential control software, which contains the commands for the command level, is located in the Flash-
EPROM on the IOC-board. The second software contains the menu structure of the C7000AT and is located in the
EPROM of the C7000AT board.
The control parameters in the IOC are resistent and do not have to be re-entered after loading the software. This is also the case for the IO bus configuration of the C7000AT.
For loading a software in the flash-EPROM of the IOC you must connect the service port of the IOC to a serial interface of your PC/Laptop by means of a RS232 modem connection.
Switch off the master switch. Set the jumper JP7 to position
2-3. The master switch must then be switched on again.
The IOC is now in the „download“-mode. Start the program
"C7000-Service.exe" on your PC. This program can be downloaded from the Stulz-website.
After the new software has been loaded, the master switch must be switched off and the jumper JP7 must be set in the position 1-2. After this switch on the master switch.
For loading a software in the flash-EPROM of the C7000AT you must connect the service port of the C7000AT to a serial interface of your PC/Laptop by means of a RS232 modem connection.
Switch off the master switch. After this the jumper X6 must be set in the position A. The master switch must then be switched on again. The C7000AT is now in the „download“mode. Start the program "C7000-Service.exe" on your PC.
After the new software has been loaded, switch off the master switch and set the jumper X6 in position B. After this the master switch must be on again. When switching on, ensure that the new version number is correctly displayed.

In the next step all parameters, if they deviate from the default settings and the bus configuration, must be readjusted.
The default language is English. If you require another language, you can change this in the „System\Languages“ menu.
E/0409/ 57/131
10.1.1 Operation of the program "C7000-Service.exe"
With an up-to-date WinXP/Vista system the program must only be copied onto the computer hard disk and can directly be started by a doubleclick. The files (C7000-Service.exe and IOC-Service.exe) must be stored in the same folder. With former WinXP versions, Win2000, WinME and Win98 the install-package which can be obtained from the e-Stulz domain must be carried out.
Start C7000-Service.exe und click on the button "Terminal", which starts the program IOC-Service.exe.
Select an interface to the PC (COM 1 - 9) and check the connection to the IOC or C7000AT by pressing the Return key. If you receive a response from the IOC/C7000AT the connection is established.
Clicking on the "Download" button opens a window, in which you can enter the file which shall be loaded. This is done by clicking on the button "Select file", which opens a dialogue windows for the selection of a file. The file is a hexadecimal file with the extension *.h86.
The file name gives information about the software destination.
C7000AT-Vxxx.H86 is destined for the C7000AT. C7000IOC-
Vxxx.h86 correspondingly for the IO-controller. The number behind the V indicates the version.
Concerning the block size and the transmission rate, you can take the preadjusted values (1024 Bytes and 38400 kBit/s).
The transmission will then take approx. 2 minutes for each software. With a longer cable however, you may be obliged to reduce the rate.
You can start the download now with the button "Start". The single steps are indicated in the "Help/State" line, the progress of each step in the "Download Progress" line.
Clicking on "Close" closes the download window. Pressing the
"End" button quits the program IOC-Service.
