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 charac­teristic 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).

EXAMPLES OF DIFFERENT HEATING SYSTEMS:
a) Floor heating
If the room temperature drops in subzero weather, raise the curve setting at -20 C. If the room temperature rises in subzero weather, lower the curve setting at -20 C. If the room temp. feels chilly at zero degree weather, raise the curve setting at 0 C. In this way you can set the regulating curve to meet the heating needs of your facility.

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 24­hour 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 circuit2is 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 ).

An appropriate room compensation ratio for floor heating is usually between 1.5 - 2.0°C.
Room sensor (TMR) must be connected (H1:meas.3, H2:meas. 6, or net).
A house cools down in windy weather. In that case the wind compensation raises the supply water temperature. The reading indicates the maximum amount that the wind compensation can raise the supply water temperature.
The room temperature of a house having large windows with a south exposure rises on a sunny day even in subzero weather. The reading indicates the maximum amount that the sun compensation can drop the supply water temp.

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).

If the HW supply water temperature exceeds the HW alarm limit (factory
setting 70 C), the alarm goes off. The present supply water temperature appears on the display. The alarm relay contact closes (strip connectors 31 and 32). See "Settings", page 21.

The regulator gives a risk of freezing alarm if the supply water temperature goes below the lower limit set for a free drop in the supply water or the lower limit set for the room temperature. The present supply water temperature appears on the display. The alarm relay contact closes (strip connectors 31 and 32). See special maintenance settings page 30.
EXTERNAL ALARMS:
Measurements 6 and 11 can also be used to indicate external alarms (potential free switch). In that case a 30k9 resistor must be connected to the strip connector of the measurement in question.
When the contact is open "1" appears on the display. When the switch closes, an alarm goes off and the alarm in question appears on the display.

The display will return to the mode it was in before the fault appeared or if there are additional sensor faults their alarm information will appear on the display. If you don't press the keyboard in 20 seconds the alarm will return to the display if the fault has not been corrected.
Deviation alarm:
The regulator gives a deviation alarm if the supply water temp permanently deviates (factory setting 60 min) from the temp set for it by the regulator. (The maximum allowed deviation is listed in special maintenance under "H1 Dev. alarm" settings and the duration of the deviation that causes the alarm to go off is under settings "DevAlaDela", page 30.)

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.

Example: A wind sensor is in use which has a measurement area of 0...20 m/s. You want wind compensation to begin when the wind velocity is 6 m/s (min. limit) and compensation to be at maximum value when the wind velocity is at least 14 m/s (max. limit). Calculate how many percent the wind compensation limits (min. limit and max. limit) are from the measurement area's maximum (=20 m/s), and set them as the minimum and maximum compensation percentages.

When you connect the wind or sun sensor to measurement 6, you instruct the regulator when you want the wind or sun compensation to function. Calculate compensation limits (min/max) in the same way regardless of which sensor is in use. The wind and sun compensation ratio indicates how many degrees compensation changes the supply water temperature and the user can set this. (See settings p. 8). The wind and sun sensor measurement signal can be 0...10 V, 2...10 V,
0...20mA or 4...20 mA. Adjust the sensors with the regulator's resistors so that the measurement message that comes from the regulator is always
0...5 V.

That which is presented on this page is in effect when a modem has not been directly connected to the controller. Communication occurs through the controller's RS-485 field bus. Many controllers can be connected to the system by using the EH-485 bus adapter card and a modem can be connected to the RS-485 field bus through the master device, EH-686.
An EH-485 bus adapter card must be installed in the controller so that the 203GT controller can be connected to the RS-485 field bus. (see installation and initialization guide in the instructions that come with the EH­485 card). Controllers that are connected to the bus are given a device ID (e.g., TC 1) so the system can identify which controller is being communicated with. The device ID always has to be written in front of the key word when communicating with the controller.

An input/output unit which contains relays, analog and digital inputs as well as analog outputs. The unit makes it possible to carry out time controlled relay functions, transfer alarms using digital inputs and make an individual regulating circuit. EH-686 can also function as a master in the Ouman RS-485 bus by directing traffic in the net.
LON -200 is an adapter card which changes the 203GT regulators' serial communication bus so it is compatible with the LON field bus. An installation guide comes with the LON-200 adapter card.
PAN-200
With the help of panel installation kit PAN-200 the regulator 203GT is easy to install for example to the control cabin. The size of the installation hole is 222 mm x 138 mm.
