Ouman C203 overview
This is the installation and configuration for C203. It describes configuration and set-up of the regulator,
customer-specific configuration as well as value settings.
The C203 is a heat regulator for three circuits that can be used to control two heating circuits and one hot
water circuit. Regulator can show in the display various usage modes depending on the connections and
configuration. You can navigate between functions by turning the C203’s selection knob. When you press
the selection knob (OK), you can view the details of specific functions.
Navigating between favourite views or
returning to basic view
• The regulator has the Basic view for
H1 circuit as default
•
Users can save their views if they
want.

Holding the key down for an extended period of time returns
the regulator to its basic mode.
The display shows the basic
view, the monitor dims and the
keyboard locks if the locking function is in use.
Alarm notice
Ouflex can generate different kinds of alarms. In the event of an
alarm, an alarm window pops up showing detailed alarm information and a beeping alarm signal goes off.
If there are several unacknowledged alarms and you acknowledge the alarm currently appearing in the device display, the previous alarm will appear. As soon as all active alarms have been
acknowledged, the alarm window disappears and the alarm signal stops.
Alarm signal of all active alarms may also be stopped by pressing
Esc button. When you press Esc, the alarm signal stops and all
the alarm windows disappear from the display.
You may look into the alarms later by going to ”Alarms” > ”Active
alarms”. If an alarm has been acknowledged by pressing Esc, an
exclamation mark appears in the beginning of the row.

Trend log
Trend log on
Explanation
From there you can view the trend log if the trend log is turned on.
The trend log is not shown in real time, i.e. the view is not updated
in real time. The interval for trend-log monitoring can be changed
and the log can be saved to a memory stick.
No
Yes/No
The trend log can hold 2,000 measurement samples. The regulator produces a separate trend log for each measurement.
Trend log sampling interval 60 s
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.
Trend log saving
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).

3.4 Delay function of radiator heating
The C203’s time-delay function can be used in regulating supply water. Outdoor temperatures have a delayed effect on room temperature, when supply water regulation should not be immediately corrected in

3.5 Anticipating of floor heating
The C203’s anticipation function can be used in regulation of supply water for floor heating locations. In
floor heating the mass heated is large, so changes in supply water temperature have a delayed effect on
room temperature. In floor heating locations, changes in outdoor temperatures should be anticipated and
supply water regulation corrected in good time when the outdoor temperature begins to change.
The regulator shows H1 circuit regulation curve settings first and then H2 circuit settings.

Anticipation of floor heating is used to try to stabilise room
temperature when outdoor temperature changes. 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.

In addition to measured outdoor temperature, temperature
forecasts from Foreca 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.
The value setting is used to select whether or not the regulation valve is closed when the summer function is in use.
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 vent
to 20% and then closes it. If the regulator has stopped the pump,
the regulator uses the pump during flushing of the valve. Valve
flushing is done at 8:00 a.m. on Mondays.

When you reset the system to factory default settings, the regulator will revert to controlled start-up
mode.
3.15 Restore backup
When the C203 has been started up and location-specific settings have been applied, a backup copy should
be made. If you have made a backup copy, you can restore from backup by pressing OK.
3.16 Do backup/ Software updates
When the C203 has been started up and location-specific settings have been applied, a backup should be
made.
When you make a backup copy, all data that needs to be retained during an electrical outage will be stored
on the memory card. These data include value settings, schedule programmes and specified names.
When you update the software but want to retain your own personal
settings, do the following:
1. Select “Do backup”.
2. Disconnect power to the regulator. Remove the memory card
from the C203.
3. Copy the object_backup_cg file from the C203’s memory card to
the memory card with the updated software.
