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.
Turn the control knob
to navigate in the menu.
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.
Press the control button to
enter the menu.
Control knob and OK
Cancel button
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.

How to acknowledge 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.
Ouman C203 can generate alarms for several dierent reasons. In the
event of an alarm, an alarm window pops up showing detailed alarm
information and a beeping alarm signal goes on.
If there are several unacknowledged alarms, the latest activated
alarm is always shown in the display. As soon as all active alarms
have been acknowledged, the alarm window disappears and the
alarm signal goes o.
Alarm signal of all active alarms may also be muted by pressing Esc
button. When you press Esc, the alarm signal stops and the last alarm
windows disappear from the display.
You may look into the alarms later by going to ”Alarms” > ”Active
alarms”. If an alarm has not been acknowledged, an exclamation mark
will appear in the beginning of the row.

Twisted pair cable is used to connect RTU devices, e.g. DATAJAMAK 2 x (2 +
1) x 0.24.
The bus cable’s fault detector (FE) is connected to the BG connector of the
C203. In the master device the fault detector can be left disconnected or be
connected to a potential free contact. A 120 Ω terminating resistor is con-
nected to both ends of the bus.
The factory default for the device’s slave address is 10 and the bus speed is
9600 bauds. If necessary, make changes to the regulator’s system settings.

As final point set the year and accept by pressing OK.
When the circuit is taken into use, you must also select a heating met-
hod. Regulation curves and settings for various heating methods have
been pre-set at the factory and usually do not need to be changed.
Select a circuit-specific heating method:
Floor heating is intended for normal floor heating
Radiator heating: suited for a number of new radiator-heated loca-
tions such as passive or energy ecient houses.
Select the type of actuator.
H2 circuit configuration follows the same steps as H1 circuit configu-
ration.
If you select ”Yes”, the regulator will display the start-up sequence
when it is powered on. If you select ”No”, the regulator will display the
basic view when it is powered on. The heating method can then be set
in the circuit settings and service mode settings. Time and language
settings are found under system settings.

switches the pump on but it does not activa-
te. The alarm has a 5 s delay.
Pump alarm: Pump indication data is supp-
lied by the frequency converter unit. The re-
gulator emits a pump alarm when a conflict
state occurs.

can be made using compensation. You can
assign names to general compensation (e.g.

The control will be taken separately into use
(see Service mode→ Temperature drops). You
can also do Home/Away control in “Measurements”-
