The basis for an even room temperature is a characteristic heating
curve of just the right shape. The right shape for a characteristic
heating curve depends on many factors.
In 203GT the characteristic heating curve can be
adapted to exactly meet the needs of the facility from three points;
203GT prevents the setting of an incorrectly shaped charac-
teristic heating curve. It automatically suggests an adjustment.

CURVE INTERPRETATION:
When the outdoor temp. is:
-20 C, the supply water is +32 C
0 C, the supply water is +27 C
+20 C, the supply water is +21 C
The temperature of the supply water may vary from the curve
if a reduced operation mode, room, wind or sun compensation
has been connected to the regulator or if one of the limiting functions
limits the temperature (see p. 11).
If the outdoor sensor is disconnected or if the sensor is broken,
the regulator assumes that the outdoor temperature is 0 C (use during
construction without the outdoor sensor).

Houses with floor heating
Set the 203GT regulator's maximum limit between +35 ... +40 C and the
minimum limit between +20 ... +25 C.
In floor heating solutions it is important to make sure that exessively hot
water which could damage structures or surfaces doesn't ever get into the
network. A mechanical thermostat should be installed on a supply water
pipe which stops the circulation pump in case of overheating. Ouman Oy
keeps CO1A surface mounted thermostats in stock that are suitable for this
purpose. Set the thermostat at 40 ... 45 C.

.
The supply water temperature drop,
determined by the clock program or the
external home/away switch. (Room
compensation takes a desired drop in room
temperature into account)
Minimum allowed supply water temperature.
Set the minimum limit for floor heating circuit
tiled floors between 20...25°C, 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. Set the upper limit for floor
heating between 35...40°C.

The automatic pre-increase in degrees which
occurs after a reduced operation (nighttime drop)
The pre-increase makes it possible to raise the
room temperature faster to a nominal room
temperature (day temp.) after a reduced
operation. A maintenance person must set the
length of the pre-increase time (see maintenance
mode p 21).
In autumn, the temperature of the supply water is
automatically raised for 20 days through autumn
drying. Autumn drying is activated when the
average temperature in a 24-hour period has
continually been above 7 °C for a period of at
least 20 days and after this drops below 7 °C.
Autumn drying is activated during the next 20
days whenever the average temperature in a 24-
hour period is under 7 °C. The autumn drying
setting indicates how much autumn drying raises
the supply water temperature. The original factory
setting is 1 °C.

Valve closed during the summer: The outdoor
temperature limit at which the regulator closes the
valve in H1 circuit. Circuit 2 is often used to warm
up the wet places (sauna stove, lavatory and so on)
Because it is important to warm up the wet places
also summer time, the valve in circuit 2 is not closed.
Room compens. Room compensation ratio: If the room
temperature is different than what it is set at,
the room compensation corrects the supply
water temperature. (Eg.) If the room
compensation is 4 and the room temperature
has risen 1,5 above the setting, the regulator
drops the supply water temperature 6
(4x1,5 =6 ).

A house cools down in windy weather. In that

SUPPLY WATER INFORMATION
In this mode we can see which factors determined by the regulator make
up the supply water temperature at the time of inspection.
The basis for this is the supply water temperature at the present outdoor
temperature according to the characteristic heating curve.
Present supply water temperature (C ) determined by the regulator
o
EXAMPLE In the example, the supply water temperature according to the
curve is 35 C. Autumn drying raises it 4 C. The outdoor
temperature measurement delay drops the supply water temp. 2 C.
As a result, the regulator determines that the supply water
temperature is +37 C. (35+4-2=37).

Self-learning occurs if the room temperature varies at least 1 C from the set
value when the outdoor temperature is in a +5... -5 C or -15... -25 C range
for at least 4 hours.
Automatic adjustment of the characteristic heating curve occurs at 0 C or
-20 C. The adjustment rate is 1 C in 4 hours. The maximum adjustment of
the set curve is +/- 10%. If the characteristic heating curve setting is changed
from the keyboard, GSM phone or control room, self-learning starts from
the beginning.
The room sensor (TMR) has to be in use in order for self-learning to take
place. The self-learning setting must not be used if the room compensation
unit (TMR/P) is in use. Self-learning does not function during a temperature
drop.
If the outdoor temperature is between -15... -25 C, self-learning occurs at
the characteristic heating curve's -20 C setting. For example, if the setting
value is 50 C, the self-learning area is 45... 55 C (+/- 10% of the set value).
If the outdoor temperature is between -5... +5 C, self-learning occurs at the
characteristic heating curve's -0 C setting. For example, if the setting value
is 34 C, the self-learning area is 30... 38 C (+/- 10% of the set value).

ALARMS!
In case of sensor fault, the regulator gives an alarm and a message
appears on the display: Alarm! Measurement number and name and err.
The alarm relay contact closes (strip connectors 31 and 32).
Measurements 6 and 11
as alarms:
203GT gives an alarm when a situation deviates from the norm. In the event of an alarm, the controller gives an
alarm and an alarm message appears on the display. Also, the alarm relay contact closes. Note! Although the
cause of the alarm has disappeared, the last alarm remains permanently on the display until it is acknowledged. If a
GSM modem has been connected to the controller, the alarm will appear in the desired GSM phone as a text
message. External alarms can also be connected to 203GT, e.g., leakage, network's water pressure, etc. (alarm
labeling is done using the text editor). The controller gives an alarm if the temp of the accumulator's upper part rises
above 95°C. In addition, with geothermal heating at full effect the controller gives an alarm if the controller switches
on the heating resistor.
Digital inputs Dig1, Dig 2 and Dig 3 can be used for receiving external alarms.
The alarms can be labeled according to topics, e.g., "water damage”
(installation p. 34). When the contact connected to the digital input closes, an
alarm goes off and "err” appears on the display. If the alarms are not labeled,
"Alarm!, Dig 1 (2, 3) will appear on the display in the event of an alarm and the
alarm relay contact closes (strip connectors 31 and 32).

The GSM modem (optional equipment) offers an economical "miniature monitor
solution”. Alarm information is directed to the desired GSM numbers (1 and 2).
See p. 37). In the event of an alarm, the regulator first sends a text to GSM1
that indicates the cause of the alarm. The alarm is acknowledged when the
same message is sent back to the regulator via the GSM. If the GSM1 does
not acknowledge the alarm in 5 minutes, the regulator will send the text
message again to both GSM numbers.

GSM-FUNCTIONS
A GSM modem can be connected to 203GT, making it possible for the user to communicate with the controller via
GSM phone text messages. (installation p. 37). A GSM phone can be used to carry out most of the user level
functions in this manual, e.g., measurements, settings, heating curve settings, supply water info and the
controllers operating mode. A GSM phone receives alarms which can be acknowledged by sending the alarms
back to the controller.
KEYWORDS
Send the following text message to the regulator:
If the regulator has a device ID (p. 37,38), always write the device ID
before the key word (e.g., TC1 KEYWORDS). The regulator will send a
list of key words via text message, which will help you obtain information
about how the regulator operates. Each key word is separated by a /
character.
Send a text message to the regulator using key words that it provides
you. The regulator recognizes only one request at a time, so write only
one key word/message. You can write the key word using capitals or
small letters. (If the regulator has a device ID (see p. 37, 38), write the
device ID in front of the key word.)

The regulator answers your request by sending the desired information.
With the GSM phone you can adjust heating curve settings, user level
settings or the regulator's operating mode.
Send the regulator a text message. Using key words, request information
about the function whose settings you want to adjust (or obtain the
information from your telephone's memory). Adjust the settings in the text
message that the regulator sent. Send a text message with the new
settings to the regulator. The regulator will make the requested
adjustments and acknowledge them by sending back a text message with
the new settings.
You can acknowledge an alarm with a GSM by sending the
same message back to the regulator.
Write the desired supply water temperature in place of
the previous setting in the text message "adjust” mode.
Write the setting in place of the previous setting
Put a star (* ) in front of the operating mode which you
want to start using. When you select manual operating,
regulator sends information about the supply water
temperature and valve positions (0-10Vcontrolled
actuators). Attention! When using electric manual control,
special caution has to be taken because of danger of
freezing and overheating. During the valve flush function,
the regulator first opens and then closes the valve.
After this automatic regulation continues. The purpose
of this function is to clean out a plugged up valve.

TUNING VALUES
203GT has three PID regulators. The tuning values may have
to be adjusted, for example, when the geothermal heating is installed
if the setting wavers with the original factory setting.
Anticipate and quick run can be set in the HW regulating circuit in
addition to PID.
Tuning takes place in the following manner:
Directions for entering the maintenance
mode are on page 19.
INFORMATION ABOUT TUNING VALUES
Explanation:
Supply water temperature change at
which the actuator runs the valve at
100%.
The deviation in the supply water
temperature from the set value is
corrected by P amount in I time.
Regulation reaction speed up in the event
of a temperature change
Uses anticipate sensor measurement
information to speed up regulation when
HW consumption changes.
Functions during consumption changes.

Attention!
Eg. If the supply water
temperature changes 10°C
and the P area is 100 °C
the position of the actuator
changes 10%.
Beware of constant waver!
Increase the anticipate
value to decrease reaction
to changes in consumption.
Decrease this value to
decrease reaction to quick
temperature changes.
The original factory settings may vary from the above. Shorten the I time (to approx. 12 seconds) in the HW 3-
way mixer.
