This user manual explains the C203 regulator’s functions and the displays that are visible to all users. The
service mode functions are covered in separate service manual at www.ouman.fi.
The regulator also has a service mode that is used when connecting and implementing features as well as
the regulator’s configuration. It includes certain setting values that do not usually need to be changed or
require in-depth knowledge of the regulation process.
The C203 is a heat regulator for 3 circuits (two heating circuits and one hot water circuit). Wiring and con-
figurating selections define what the regulator displays on the display screen.
Turn the control knob
to navigate in the menu.
A maximum of five windows can be displayed with the favourite
views key. Default settings for favourite views show menus for
each circuit, including all default settings that can be changed
by the user as well as information about measurements and the
regulator’s operation.
You can move from one favourite view to another by tapping
the key.
Press the control button to en-
ter the menu.

Central factors related to controlling heating are visible in the regulator’s basic view. When the unit is dor-
mant (keys have not been touched) the display shows the basic view.
Dierent levels of display menus are used to make the C203 clear and easy to use. The basic view shows the
most important information for monitoring operation of the unit. Favourite views that can be changed by
users enable them to easily access desired menus. Setting values needed by the user can easily be found in
the versatile menu structure.

1.1 Basic view
C203 can generate dierent kinds of alarms. In the event of an alarm,
an alarm window pops up showing detailed alarm information and a
beeping alarm signal goes o.
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 will appear in the beginning of the row.
Alarm notice
Acknowledging alarms: Press OK and
the alarm sound will stop. If the reason
for the alarm has not been corrected, the
exclamation point in the top right will
continue to blink.

You can see the measurements and mode information linked to the
C203. When you press OK on the measurement row, you can see
the measurement’s trend or trend log, change the settings of the
trend log and change the name of the measurement.
General measurements are informational temperature measu-
rements with names set by the factory for a particular use. The
general measurement can also be put to a dierent use and be re-
named.
If the sensor is not connected or is defective, the measurement va-
lue shown will be -50 or 130 °C.
You can also see circuit-specific measurements under each circuit.

When you press OK on ”measurement,” a menu for viewing trends and chan-

to better describe what is being measured.
Measurement channels continuously monitor trends. Trends show measure-
ments from the past 45 seconds. The measurements displayed are updated at
one-second intervals.

The trend log can hold 2,000 measurement samples. The regulator produces a
separate trend log for each measurement.
You can change the name of the measurement shown in the display. If the measu-
rement is circuit-specific, the identifier for the circuit appears before the measure-
ment, e.g. O1 (=H1).
A dierent sampling interval can be set for dierent measurements. The memory
can store 2,000 measurement samples. For example, if the sample interval is 60
seconds, the trend buer will contain measurement information for 33 hours. If the
sampling interval is 1,800 seconds (30 minutes) the buer will contain measure-
ment 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 M-LINK (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 measure-
ments).

The C203 enables control of two dierent supply water circuits
independently (H1 and H2).
Regulation of the temperature of supply water is controlled by
the outside temperature. Use of room temperature measurements
keeps room temperature more consistent.
3 Regulation of supply water in heating circuits
3.1 Supply water information (Woda na zasilaniu – informacje)
The supply water info shows which factors are aecting the supp-
ly water temperature at the time of inspection. The starting point
is the supply water temperature according to the
outdoor temperature (according to the heating curve).

average p. 13)

When the regulator is in summer function mode, the supply water information says
”Controller is stopped for summer.”

In the example in the picture, supply water according to the heating curve is
35.1°C. In the Away mode the controller reduces the temperature of the supply
water to 6.0°C. Based on these data, the computational setting value of supp-
ly water is 29.1°C (= 35.1 - 6.0).
3.2 Room temperature information (Informacja o temp.pokojowej)
3.3 Measurements (Pomiary)
If a room sensor is connected to the controller, you can check the
room temperature info to see which factors determine the room
temperature at the time of inspection. The basis is the setting va-
lue of room temperature.
The ”Pomiary (Measurements)” menu under the circuit shows the measurements related to the circuit.
All measurements connected to the regulator can be found in the Measurements menu at the root level (see
page 7).

The supply water temperature for dierent outdoor temperatures
is set in heating curve settings. With C203 the heating
curve can be adjusted exactly to meet the needs of the facility from
either three or five points. A 5 point curve is the factory setting.

Setting Factory
setting Explanation
Note! Changes influence room temperature slowly. Wait at least 24 hours before readjusting the settings. Es-
pecially in buildings with foor heating, the delays in room temperature changes are quite long.
If room temperature drops, make the curve steeper. (Set higher values for
supply water temperature at the outdoor temperatures -20 °C and 0 °C).
If room temperature rises, make the curve less steep.
(Set lower values for supply water temperature at the outdoor temperatures
-20 °C and 0 °C).
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 o during the setting. The curve is appropriate when the room
temperature is maintained constant although the outdoor temperature changes.

2 hours. If the room temperature rises too much when tempera-

Anticipation speeds up regulation when water consumption
changes by using measurement information from the circulation
water sensor. The regulator recognises the sensor and automati-
cally starts to use anticipation when the sensor is turned on. You
can also stop using anticipation.
