Holding the key down for an ex-
tended period of time returns the
regulator to its basic mode. The
display shows the basic view, the
background light of the display
dims and the keyboard locks if the
locking function is in use.
This user manual consists of two parts. Issues that are intended for all users are presented in the first part
of user manual. The issues related to service mode are at the end of it. In addition there are issues, which
are only intended for persons in maintenance or who has in-depth knowledge of the control process.
The S203 is a heating controller for 3 circuits (two heating circuits and one hot water circuit). Wiring and
configurating selections define what is seen on the display screen.

Central factors related to controlling heating are visible in the regulator’s basic view. When the unit is idle
state (keys have not been touched for a while) the display shows the basic view.
Dierent levels of display menus are used to make the S203 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 us-
ers enable them to easily access desired menus. Setting values needed by the user can easily be found in the
versatile menu structure.

Ouman S203 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 the alarm sound is
not turned o (see page 29).
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 sig-
nal 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.

When controller is configured, it’s possible to disable alarms. When the
alarms are disabled, the symbol will be displayed in the main menu.
Alarms are enabled in the service mode → Alarm settings → Alarms:

Acknowledging alarms: Press OK and
the alarm sound will me muted. If the
reason for the alarm is still present,
the exclamation point in the top right
will continue to blink.

2 Inputs and outputs
You can see the inputs and outputs of S203 which are configured
in use. Configuration of the inputs and outputs is done in ser-
vice menu (see p. 38-39).General measurements are temperature
measurements witch can be used for serial dierent purposes. The
default names of the measurements can be changed according to
use case.
If the sensor is not connected or is defective, the measurement
value shown will be -50°C (cross sensor) or +130 °C (sensor circuit
shorted). If a measurement is in manual mode, a hand image is
shown in the beginning of the line.
Inputs and outputs
Inputs and outputs are shown by the regulator in circuit-specific
groups. First H1, then H2 and last DHW

The S203 enables control of two dierent supply water circuits in-
dependently (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 Info
The info shows which factors are aecting currently the supply
water temperature control. The starting point is the supply water
temperature according to the outdoor temperature (according to
the heating curve).
If a room sensor is connected to the controller, you can check which
factors currently determine the room temperature setting value
at the time of inspection.
In addition the info menu contains the measurement temperature
data aecting to supply water control and information of control
of actuators.

Factors eecting the supply water temp. Explanation
According to curve Supply water temperature setting according to the curve at the current outdoor
temperature.
Eect of parallel shift Eect of parallel shift on the supply water temperature.
Eect of time program Eect 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 in-
crease the temperature of supply water.
Force control eect Supply water has been forced permanently to the desired temperature reduction
level (see Control mode selection).
Away -control eect ”Away” control for reduction of supply water temperature. The trigger can come
from the Home/Away switch, the controller or be sent as a text message (see 41).
Outdoor temp. delay eect The eect of the outdoor temperature delay on the supply water temperature.
Floor heat. anticipate Eect of anticipation of floor heating on the temperature of supply water.
Eect of autumn drying Eect of automatic autumn drying on the supply water temperature.
Return water compensation Increase in supply water temperature due to return water compensation.
Eect of room compensation Eect of room compensation on the supply water.
Room comp. time adjustment Additional correction for more precise room compensation based on realised regu-
lation (eect of I-regulation).
Bus compensation eect The amount of required compensation is determined by an external device to the
S203, for example from bus compensation to weather compensation.
Min limit eect Supply water temperature increase due to the minimum limit.
Max limit eect Supply water temperature drop due to the maximum limit.
Calculated supply water setting Current supply water temperature determined by the controller.
Controller is stopped for summer When the regulator is in summer function mode, the supply water information says
”Controller is stopped for summer.”
Controller is in manual control Control circuit mode is set to ” Manual control”.
