The correct shape for the characteristic heating curve depends on many factors (the insulation in a house, type of heat distribution, the dimensions of the piping, etc.). A heating curve is typically set so that the supply water temperature rises when the outdoor temperature drops. Ouman EH-203s characteristic heating curve can be adjusted to exactly fit the needs of the facility from either three or five points. A 3-point curve is a factory setting. A 5-point curve can be taken into use in the special maintenance mode. (see p. 34).

OPERATING INSTRUCTION: Press ESC until the display no longer changes. You are then in the Selection display shown in the adjoining picture.

Use the button to move from one regulating circuit to the next (H1, H2).

Press the button to move cursor to Heating curve Press OK.

3-point curve (factory setting): You can adjust the characteristic heating curve using outdoor temperature settings — 20C, 0C and +20C. EH-203 prevents you from setting characteristic heating curves that are the wrong shape. It automatically proposes a correction.

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 Attention! 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 outdoor temperature is 0 C (use during construction without the outdoor sensor).

EXAMPLES OF DIFFERENT HEATING SYSTEMS:

A) Normal radiator network (H1 circuit, factory setting)

B) Floor heating C) Preheating for air conditioning (H2 circuit, factory setting)

INSTRUCTION: If the room temperature drops in sub zero weather, raise the curve setting at -20 C. If the room temperature rises in sub zero weather, lower the curve setting at -20 C. If the room temp. feels chilly at zero degree weather, raise the curve set- ting at 0 C. In this way you can set the regulating curve to meet the heating needs of your facility. Parallel shift: If the room temperature remains constant, but it is either too cold or too hot, the characteristic heating curve can be moved using a parallel shift. The number of degrees of the parallel shift indicates the amount the characteristic heating curve is moved on the supply water temperature scale. Note! Wait for a sufficient length of time after the settings have been ad- justed so the adjustment has time to effect the room temperature.

The 5-point characteristic heating curve bisects 5 adjustment points. In addition, the supply water temperature can be limited by setting minimum and maximum limits for the supply water. (see p. 6).

With a 5-point curve, the supply water temperatures are set for outdoor temperatures -20 C and +20 C. In addition, three other outdoor tem- peratures can be set between -20 C and +20 C that are given supply water temperatures.

The supply water temperature setting range is +5 C +120 C for each adjustment point.

Room sensor (TMR) must be con- nected (H1:meas.3, H2: meas. 6, or net). An appropriate room compen- sation ratio for floor heating is usu- ally between 1.5 — 2.0C.

Transmitter must be connected, the same sensor for regul. circuits H1 and H2 (meas. 6).

Room temperature setting, which user has set. During temp. drop period regulator use the calculated room temp. setting.

The supply water temperature drop, determined by the clock program or the external home/away switch. (Room com- pensation takes a desired drop in room temperature into ac- count).

Minimum allowed supply water temperature. Set the minimum limit for floor heating circuit tiled floors between 20…25C, 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 set- ting is incorrect, the maximum limit prevents excessively hot water from entering the network. Set the upper limit for floor heating between 35…40C.

A parallel shift occurs when a change in supply water tem- perature occurs at each adjustment point.

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 set- ting, the regulator drops the supply water temperature 6 C (4×1,5 C =6 C)

E-compensation ratio: Compensation relation shows how much the E-compensation can, at the most, make the heating water temperature rise or sink. E-compensation is used for example where wind and sun measurement is used.

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 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 5 C for a period of at least 20 days and after this drops below 5 C. Autumn drying is acti- vated during the next 20 days whenever the average tem- perature in a 24-hour period is under 5 C. The autumn drying setting indicates how much autumn drying raises the supply water temperature. The original factory setting is 2 C.

When the temperature of measurement 10 drops to the set lim- it, the regulator causes relay 1 to turn the burner on (see p. 26).

When the temperature of measurement 10 drops to the set limit, the regulator causes relay 2 to switch on the heating re- sistor (see p. 27).

Valve closed during the summer: The outdoor temperature limit at which the regulator closes the valve/valves. A factory setting is that only the valve in the H1 circuit closes. If the maintenance person has selected H1 Valve regul or H2 Valve regul under pump summer stop, the function is not on in that particular circuit. Select H1 (H2) Valve close in pump summer stop for that function to be on (see p. 26).

Pump summer stop: Outdoor temperature at which the regu- lator stops the pump. During connection and installation, the maintenance person decides whether to stop both the H1 and H2 circuit pumps and whether the valves will continue regulat- ing or whether they will close (each of the valves functions is determined separately, see maintenance mode page 26).

Domestic hot water temperature setting. Because of danger of bacteria, it is recommended that the domestic hot water tem- perature is not set below +55C.

Select relay 1 for burner control.

If heating pump control has been selected for relay 1s control function, this set- ting becomes the pumps summer stop limit.

Pump stop appears in place of the valve sum- mer close setting if heating pump control has been se- lected in the relay 1 control mode (p. 25). Can be set when relay1 is selected to temp. operated function (p.26).

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.

EXAMPLE In the example, the supply water temperature according to the curve is 35.5 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 +37.5 C. (35.5+4-2=37.5).

If — appears in place of the measurement value, the controller has not read the measurement information in question. The reason for this may be that the energy meter does not support this measurement. Momentary output and Momentary flow energy meter measurements can be read from the controllers Measurements menu.

Use the key word DH ENERGY to receive via text message the same measurement information that is in the controllers menu. The same text message can be automatically sent monthly on a selected day to two different GSM numbers. (e.g., a report to the electric company and caretaker). Instructions on p. 34 Energy meter.

*) Use the keyword Measurements to obtain information about the facilitys district heating output and water consumption.

Ouman EH-203 has a connector for the read head. The function is acti- vated in the controllers special maintenance menu (see Energy meter p. 35).

Measurement information can be read from the controllers display and it can also be read from the net or as text messages, if these functions have been taken into use.
