The trend log can hold 2,000 measurement samples. The regulator produces a separate trend log for each measurement.

A different sampling interval can be set for different measurements. The memory can store 2,000 measurement samples. For example, if the sample interval is 60 seconds, the trend buffer will contain measurement information for 33 hours. If the sampling interval is 1,800 seconds (30 minutes) the buffer will contain measurement history for 41 days.

The trend log can be saved to a memory stick. A csv file is created on the memory stick, which is named according to the point measured. For example, the trend log for outdoor temperature is saved in a file named UI1.csv.

You can set the regulator to automatically create a csv file at the intervals that have been set and forward the data to Oulink (additional equipment). If the trend log becomes full before the interval for saving data has passed, the regulator will save the data immediately when the log is full (2,000 measurements).

Effect of parallel shift on the supply water temperature

Effect of weekly or exception schedule mode on the temperature of supply water. Near the end of the temperature reduction time, the pre-increase operation can increase the temperature of supply water.

Supply water has been forced permanently to the desired temperature reduction level (see Control mode selection).

”Away” control for reduction of supply water temperature. The control command can come from the Home/Away switch, the regulator or be sent as a text message (see 29).

Effect of anticipation of floor heating on the temperature of supply water.

Value - how much the reduced value of outdoor temperature measurement affects the setting value seen in the supply water curve..

Effect of automatic autumn drying on the supply water temperature.

Increase in supply water temperature due to return water compensation.

Effect of room compensation on the supply water

Additional correction for more precise room compensation based on realised regulation (effect of I-regulation).

General compensation can be based for example on wind, solar or pressure measurements.

The amount of compensation required is determined by a device outside the regulator that conveys information to the C203, for example from channel compensation to weather compensation.

Supply water temperature increase due to the minimum limit.

Supply water temperature drop due to the maximum limit.

Present supply water temperature determined by the controller. All the factors are considered that affect the supply water temperature.

The preset heating curves are typical average curves for the heating mode in question. The curve may need to be adjusted to suit your building. The setting should be done during the cold period and if the room compensation is in use, it should be switched off during the setting.

Note! Changes influence room temperature slowly. Wait at least 24 hours before readjusting the settings. Especially in buildings with foor heating, the delays in room temperature changes are quite long. The supply water minimum limit setting ensures that pipes will not freeze. The maximum limit setting ensures that excessively hot water that could damage structures (e.g. parquet in case of foor heating) does not enter the heating system.

Explanation

Minimum allowed supply water temperature. A higher minimum temperature is used in damp rooms and tiled rooms than in, e.g., rooms having a parquet floor to ensure a comfortable temperature and removal of moisture in the summer.

Maximum allowed supply water temperature. The maximum limit prevents the temperature in the heating circuit from rising too high, preventing damage to pipes and surface materials. If, e.g., the characteristic heating curve setting is incorrect, the maximum limit prevents excessively hot water from entering the network.

Summer function outdoor temperature limit. When the measured or forecast outdoor temperature exceeds the outdoor temperature limit of the summer function, the regulation vent closes and the circulation water pump stops as selected.

If the regulator is connected to control the pump, the pump can be stopped while the summer function is in use.

The setting value is used to select whether or not the regulation vealve is closed when the summer function is in use.

The setting value shows how much the autumn dry function increases supply water temperature. If room temperature regulation is in use, the user sets how much the room temperature is increased.

The flushing operation is done in connection with inspection of the valve’s position when the regulator is in summer function mode.

During the flushing operation the regulator opens the valve to 20% and then closes it. If the regulator has stopped the pump, the regulator uses the pump during flushing of the valve.

In addition to measured outdoor temperature, temperature forecasts can be used with the summer function (requires

Ounet connectivity). If the regulator has not received outdoor temperature forecasts via the data channel for 2 hours, the forecast is not used in the summer function.

Time/

24 hours

In autumn dry mode, supply water temperature is automatically raised for 20 days. The function is turned on automatically when the average daytime temperature has been more than 7°C for a minimum of 20 days and then falls below +7°C. The function remains on for the following 20 days if the outdoor temperature is below 7°C (10 hour time constant for measurement).

In floor heating, the concrete mass of the floor slows transmission of heat to room air temperature. If room temperature rises too much when temperatures below freezing rise, increase anticipation.

If room temperature falls too much when freezing temperatures fall further, increase anticipation. If the opposite occurs, lower anticipation.

Room compensation correction time can change supply water temperature to no more than this setting value. If room temperature continuously fluctuates, check whether the problem is resolved by lowering the setting value.

General compensation can increase or decrease the temperature of supply water. Transmitter measurement can utilise for example wind or solar measurement or a pressure differential measurement over the heating network.

Setting limit values for a compensation area. Set the transmitter measurement message value at which compensation begins and the value at which it reaches its maximum level. The amount of compensation is linear between the limit values. (Implementation of a transmitter and setting values for the measurement area are done during implementation of measurement.)

The compensation minimum tells you how much supply water temperature is changed when the supply water compensation starts.

Maximum compensation shows the maximum amount that compensation can raise or lower supply water temperature. If wind measurement is used in transmitter measurement the setting value is positive, i.e. supply water temperature is raised due to the wind. If solar measurement is used in transmitter measurement the setting value is negative, i.e. supply water temperature is lowered due to solar radiation.

°C

An example of general compensation. A wind sensor is connected to the measurement channel. Wind compensation should start when the transmitter’s measurement message is 30% and reach its maximum when the measurement message is 70%. Wind compensation can raise supply water temperature by no more than 4°C.

Filtering of measurement signal. The filtering will dampen the effect of rapid changes.

The need for compensation can be defined by an external device that relays the need for a supply water temperature exception to the C203 through a communication channel (e.g. Ounet

S-compensation).

Channel compensation cannot drop supply water temperature more than allowed by the setting value.

Channel compensation cannot increase supply water temperature more than allowed by the setting value.

If return water temperature falls below the setting value for danger of return water freezing, supply water temperature is raised by the value: amount of the deficit multiplied by the compensation ratio.

There are two alternative ways to set the C203 device IP address and network settings:

1. IP address is retrieved via DHCP function. This requires that DHCP service is in use in the network and network cables have been connected.

2. IP address is set manually.

Setting the IP address via DHCP function:

1. Go to DHCP and press OK.

2. Select ”On” and press OK to accept selection.

3. Select ”Update network settings” and press OK to accept selection.

4. Wait approximately one minute.

5. If DHCP is ”On”, setting the IP address and other network settings was successful. The device now functions in the network.

6. Otherwise, make sure the connections and the fact that the network has a DHCP server.

Setting the IP address manually:

1. Go to DHCP and press OK.

2. Select ”Off” and press OK to accept selection. If DHCP function is on, manual changes in ”Subnet mask”, ”Gateway address”, ”Name server address” and ”IP address” will be ignored.

3. Select ”Start” -> ”Run” to open Windows command prompt in your

PC.

4. A window opens. Type ”cmd” in the text field. Select ”OK”.

5. Type ”ipconfig/all” in the command prompt and press ”Enter”. C203 can be connected to intranet in case the IP address begins with:

6. Take down the following information:

- Name server address in the first view

• 10.x.x.x (e.g. 10.2.40.50)

• 192.168.x.x (e.g. 192.168.0.2)

• 172.16.x.x – 172.31.x.x (e.g. 172.18.0.5 )

If the IP address does not begin with any of these sequences, it usually means that:

• The subscriber connection does not have a firewall in use, i.e. it is a public IP address. C203 can not be connected to property intranet under these circumstances.

- IP address, e.g. 10.2.74.146

- Subnet mask, e.g. 255.255.255.0

- Gateway, e.g.10.2.74.1

7. Type ”Exit” to close the command prompt.

8. Go to ”System settings”-> ”Network settings” in your C203 device.

9. Enter the address you wrote down in step 6 + 10 in the IP address field (e.g. 10.2.74.146 + 10 = 10.2.74.156). Enter the first figure of the address and accept. Do the same with the second, third and fourth figure. (The fourth figure must be between 1 and 253. The set figure should not be reserved for another device.)

10. Enter the subnet mask you wrote down in step 6.

11. Enter the gateway address you wrote down in step 6.

12. Enter the first name server address you wrote down in step 6.

13. Select “Update network settings”

A tip! How to set the network settings easier and faster

You can make setting of the IP settings easier

• if you know DHCP service exists in the network

• if you know the DHCP address range and fixed address range in the network

• if you wish to use a fixed IP address.

1. First, set DHCP function On. After the settings have been set successfully, set DHCP Off.

2. Change only IP address manually. (A fixed IP address must fit the fixed address range).

Modbus TCP port (internal registers): Port number 502 is reserved for communication of C203 device. Information of Modbus registers of C203 device are read through this port.

Max connections: It is possible to decrease server load by changing this setting that defines the maximum number of simultaneous connections from different IP addresses to the server.

Idle timeout: This setting defines the time after which the server closes an inactive connection.

Allowed address: It is possible to improve the information security of the system by taking permitted connection address into use. If the value is 0.0.0.0, connections to the server are permitted from any IP address. If you define one permitted connection address, connections to the server are not permitted from any other IP address.

Function on: This selection either enables or disables the entire Modbus/TCP communication.

Modbus TCP/IP gateway ->Modbus 1 port: It is possible to connect a Mod-

Bus/RTU bus to an C203 device. The bus has its own port address that is used to communicate with bus devices via Modbus/TCP interface. Port 1 setting defines the TCP/IP port that functions as a gateway to Ouflex I/O extension bus.

Oulink supports Ouman Access-service which gives you a secure remote connection to the C203 device. With this setting you can activate the ACCESS-service in order to be able to use it.

OUMAN ACCESS- service is “on” by default in C203. OUMAN

ACCESS- service is taken in use in following way: Ouman salesperson feeds in the target and billing information to the Ouman system and activates the service based on the serial number of the C203 device.

OUMAN ACCESS- device can be connected to LAN if following conditions are fulfilled:

1. LAN is routed to internet

2. The VPN ports used by ACCESS are not blocked

1. LAN is routed to internet

Access –service uses internet. Therefore it is available only if the local

LAN has connection to internet. ACCESS-device examines the availability internet connection once per minute by sending a ping-package to a server in internet.

Network has to allow ICMP towards internet and also allow the response message to come back to C203.

2. The VPN ports used by ACCESS are not blocked

ACCESS-service is using VPN to the internet connection.

Network has to allow UDP communication from any port towards port

1194 in internet and the responces from that port back to C203 device.

If a GSM modem is connected to the C203 you can communicate with the regulator by text message using command words.

Send the following text message to the controller: KEY WORDS.

You can send the text message question mark to the controller to get a list of key words. If the controller has a device ID in use, always write the device ID in front of the key word (example. Ou01 KEY WORDS or Ou01 ?).

Capital and small letters are different characters in the device ID!

The controller sends a list of key words as a text message that gives you information about the controllers’ function. The key word is separated by a /.

You can write the key word using capital or small letters. Write only one key word/message. Store the key words into your phone’s memory.

Explanation

Reply messages show all commands in the language that has been selected for the regulator.

If the regulator is set up in English, the regulator sends a list of commands.

C203 goes into ”Home” mode.

C203 goes into ”Away” mode.

The most important measurement information is shown in the reply message.

The reply message shows the computational setting value of supply water. Data are informational.

The most important setting values are shown in the reply message.

You can change the setting values. Send a changed message back to the regulator, and it will make the change to the setting value and send you another message showing the changes to the setting values.

In the reply message, the current control mode will have a star next to it. You can change the mode for the circuit by moving the star and sending a change message to the regulator.

If a 3-point heating curve is in use you can change the supply water temperatures for outdoor temperatures -20, 0 and +20°C, as well as the minimum and maximum setting values for supply water. If a

5-point heating curve is in use you can set temperatures for supply water for 5 outdoor temperatures. Of the outdoor temperatures two are fixed values (-20 and +20°C). You can change the three outdoor temperature setting values between these. You can also change the minimum and maximum limits of supply water.

The reply message will show the setting value for domestic hot water and its mode. You can also change the setting and mode.

The reply message will show all active alarms.

Frequently Answers and Questions

What is the C203 regulator used for?
The C203 regulator controls two heating circuits, for example, radiators and floor heating, and one domestic hot water circuit. It regulates the temperature of the supply water based on the outdoor temperature and can also take room temperature measurements into account.
How do I set the temperature drops for the circuits?
The C203 allows you to set separate temperature reduction settings for each circuit. This allows you to create individual schedules for each circuit and ensure optimal comfort and energy efficiency.
Can I monitor the system's operation and make adjustments using a mobile phone?
Yes, the C203 supports communication via a mobile phone. You can receive informative messages, change setting values, and control the system using text messages (SMS). You can also change the control mode using an asterisk (*) in your SMS message and utilize the Home/Away control for temperature reduction.
