Explanation:

Room temperature setting, which user has set.

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.

Maximum allowed supply water temperature.

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 °C above the setting, the regulator drops the supply water temperature 6 °C (4x1,5 °C =6 °C).

Wind compensation ratio: Ahouse 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 compens. can raise the supply water temperature.

Technical information

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 Ouman EH-201/L the characteristic heating curve can be adapted to exactly meet the needs of the facility from three points;

EH-201/L prevents the setting of an ncorrectly shaped characteristic heating curve. It automatically suggests an adjustment.

CURVE INTERPRETATION:

When the outdoor temp. is:

-20 C, the supply water is +58 C 0 C, the supply water is +41 C

+20 C, the supply water is +18 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. 10). If the outdoor sensor is disconnected or if the sensor is broken, the regulator assumes that the outdoo temperature is 0 C (use during construction without the outdoor sensor).

EXAMPLES OF DIFFERENT HEATING SYSTEMS:

B) Floor heating

C) Preheating for air conditioning

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 EH-201/L 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 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 (see page 23).

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 for a period of at least 20 days and after this drops below 7 . Autumn drying is activated during the next 20 days whenever the average temperature in a 24-hour period is under 7 . The autumn drying setting indicates how much autumn drying raises the supply water temperature. The original factory setting is 2 .

Valve closed during the summer: The outdoor temp. limit at which the regulator closes the valve. If the mainten. person has selected "H1 Valve regul" under pump summer stop, the function is not on in that particular circuit. Select "H1 Valve close" in pump summer stop for that function to be on (see p. 26). The factory setting is hat the alve is closed.

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

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 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 58 C, the self-learning area is 52... 64 C (+/- 10% of the set value). If the outdoor temperature is between -5... +5 C, selflearning occurs at the characteristic heating curve's 0 C setting. For example, if the setting value is 41 C, the self-learning area is

37... 45 C (+/- 10% of the set value).

If you don't press the keyboard in 20 seconds the alarm will return to the display if the fault has not been corrected.

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. 39). 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.

In addition, the alarm relay contact closes. Note! Although the reason of the alarm is no more valid, the last alarm will remain into display intil it is acknowledged. If a GSM modem has been connected to the regulator, the alarm will appear in the desired GSM phone as a text message. External alarms can also be connected to EH-201/L, e.g., leakage, network's water pressure, etc. (alarm labeling is done using the text editor). If meas. 9 is reserved for exhaust measurement, the regulator gives an alarm if the exhaust temperature is too high or too low. (see p. 33)

OUMAN EH-201/L GSM-FUNCTIONSOUMAN EH-201/L

When a GSM modem is connected to EH-201/L, a GSM telephone can be used to communicate with the regulator via text messages (installation p 38). Almost all of the user level functions that are mentioned in this manual can be carried out using a GSM phone. These include measurements, settings, heating curve settings, supply water information and the regulator's operating mode. Clock programs can be bypassed permanently or for certain periods of time. Alarms are also directed to a GSM phone. They can be acknowledged by sending the alarm message back to the regulator.

KEYWORDSSend the following text message to the regulator:

If the regulator has a device ID (p. 35,36), always write the device ID before the keyword (e.g., TC1 KEYWORDS). The regulator will send a list of keywords via text message, which will help you obtain information about how the regulator operates. Each keyword is separated by a / character.

Send a text message to the regulator using keywords that it provides you. The regulator recognizes only one request at a time, so write only one keyword/message. You can write the keyword using capitals or small letters. (If the regulator has a device ID (see p. 38,39), write the device ID in front of the keyword.)

Receiving information from the regulator:

Operating the regulator using a GSM:

The regulator answers your request by sending the desired information.

With the GSM phone you can adjust heating curve settings, user level settings, the regulator's operating mode, or time-controlled relay operation. Send the regulator a text message. Using keywords, 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 temp. and valve positions (0-10V controlled 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.

A GSM can be used to control the relay only if the relay is being time controlled. Place a star (* ) next to the control mode that you want to begin using. In time control you can also set the length of time it is in effect (range 0 …999 min).

Directions for entering the maintenance mode are on page 21.

EH-201/L has two 230VAC/6A relays. Relay 1 is a break before make contact relay and relay 2 is an on/off relay. The relays can be used for many different purposes. If the relay has been selected for time control use, it can be labeled according to its use using the text editor (e.g., sauna, outside door etc.). Relays are time controlled in the regulator's clock functions (p. 14 - 15). A GSM phone can be used to bypass a relay's time program and the relay can be timer controlled or set in a continuous ON or OFF mode.

Not in use

The pumps stop (relay 1's space 73 and 74 opens) and the selected valves close when the outdoor temperat. is warmer than the "Pump stop" setting. During a stop period the regulator starts the pumps for a few minutes every day to prevent them from getting stuck (interval use).

The regulator time controls any electric apparatus using the relay, eg. a sauna stove, door locks. Timing programming is done in clock functions (p. 15). In the timing program's "ON" mode the relay is activated. The control mode can also be changed using a GSM

telephone (see p. 20).

The regulator controls relay 1 by time. In the "ON" mode the relay is activated. The "ON" mode is prevented if the outdoor temperature is colder than the relay 1's set outdoor temperature limit. (See p. 30). Timing/ outdoor temperature control is suitable for exhaust fan control

When you have reserved relay 1 for 230V actuator control, the regulator automatically also reserves relay 2 for 230V actuator control if relay 2 is free. If relay 2 is not free, the regulator first requests to free relay 2 for 230V actuator control. After this you can begin using 230VAC 3-point control in the "actuator selection" mode (see page 25)

When the control mode selected for relay 1 is "GeothHeatFull", the regulator automatically reserves relay 2 to control the compressor of the geothermal heating and reserves digital input 1 for geothermal heating selector switch position information (automatic position = strip connector 21-22 closed).

Relay 1 controls heating resistor. The regulator controls the compressor or the heating resistor according to the accumulator temperature set by the user. The compressor and heating resistor cannot be on at the same time. The heating resistor is switched on at the ["GeothHeatAcc." setting -hysteresis - 10°C] temperature ( ). is switched off at the ["GeothHeatAcc." setting - hysteresis + 2°C] temperature

Before selecting geothermal heating for relay 1, make sure that relay 2 is in a "Not in use" mode and the geothermal heating unit selector switch (start up / autom.) is connected to digital input 1 strip connectors 21 - 22.

The regulator controls the relay according to the boiler water temperature (meas. 10). The relay is activated at the setting (73-75 closed) and the burner starts up. The relay is released (73-74 closed) and the burner shuts off when the boiler water temperature reaches the "setting” + "hysteresis” temperature. The function can be selected when measurement 10 is connected.

The regulator controls relay 1 according to the temperature of measurement 11. The break before make contact relay is activated at the setting (73-75 closed) and released (73-74 closed) at the end of the set hysteresis (setting - hysteresis). E.g., a cooler's compressor or an accumulator's charging pump can be controlled with a temperature controlled relay. You can also adjust the temperature setting for measurement 11 on the user level (seep. 8)

Burner control

When the control mode selected for relay 1 is "GeothHeatPart", the regulator automatically reserves relay 2 to control the compressor of the geothermal heating and reserves digital input 1 for geothermal heating selector switch position information (automatic position = strip connector 21-22 closed). Before selecting geothermal heating for relay 1, make sure that relay 2 is in a "Not in use" mode and the geothermal heating unit selector switch is connected to the digital input 1 strip connectors 21 - 22 (start up / autom.). The regulator controls the compressor and heating resistor according to the accumulator temperature set by the user(see p. 8). The regulator alsocontrols the compressor according to the temperature needed in the heating network. Relay 1 controls the heating resistor. Heating resistor is switched on at the ["GeothHeatAcc" setting - hysteresis - 3 °C] temperature (strip connector 73-74 closed). Heating resistor is switched off at the ["GeothHeatAcc." setting hysteresis + 2°C] temperature (strip connector 73-74 open). The compressor and heating resistor can be on at thesame time.

Switching the heating resistor on and off:

Relay 2 switches the heating resistor on and off according to the temperature of measurement 10. The factory setting at which the heating resistor switches on is 50°C (setting range 5…95°C) and the hysteresis is 5°C (setting range 1…10°C).

If EH-201/L is used for burner control (see p. 26-27), the regulator can also control the heating resistor according to the same measurement data (meas. 10). There is a separate setting for switching on the heating resistor. The heating resistor can be used as an extra source of heat or the main source of heat depending on whether the setting is higher or lower than the point at which the burner starts up.

When you connect the wind or sun sensor to measurement 3, you instruct the regulator when you want the wind or sun compens. 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. 6-7). 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 regulator. Communication occurs through the regulator's RS-485 field bus. Many regulators can be connected to the system by using the EH-485 bus adapter card and connecting a GSM modem to the field bus through the master device, EH-686. Regulators that are connected to the bus will be given a device ID (e.g., TC 1) so the system will identify which regulator is being communicated with. The device ID always has to be written in front of the keyword when communicating with the regulator.
