2.0 Installation

2.1 Before you start

The application A230 is very flexible. These are the basic principles:

Heating (application A230.1):

Typically, the flow temperature is adjusted according to your requirements. The flow temperature sensor S3 is the most important sensor. The desired flow temperature at S3 is calculated in the ECL controller, based on the outdoor temperature (S1) and the desired room temperature.

The lower the outdoor temperature, the higher the desired flow temperature.

By means of a week schedule, the heating circuit can be in

‘Comfort’ or ‘Saving’ mode. The week schedule can have up to 3

‘Comfort’ periods / day. A value for the desired room temperature can be set in each of the modes.

In Saving mode the heating can be reduced or switched off totally.

The motorized control valve M1 is opened gradually when the flow temperature is lower than the desired flow temperature and vice versa.

The return temperature S5 to the district heating supply should not be too high. If so, the desired flow temperature can be adjusted

(typically to a lower value), thus resulting in a gradual closing of the motorized control valve.

In boiler-based heating supply the return temperature should not be too low (same adjustment procedure as above).

Furthermore, the return temperature limitation can be dependent of the outdoor temperature. Typically, the lower the outdoor temperature, the higher the accepted return temperature.

If the measured room temperature (directly connected temperature sensor ESM-10 (S2) or Remote control unit ECA 30 / 31) does not equal the desired room temperature, the desired flow temperature can be adjusted.

The circulation pump, P1, is ON at heat demand or at frost protection.

The heating can be switched OFF when the outdoor temperature is higher than a selectable value.

A connected flow or energy meter based on pulses (S7) can limit the flow or energy to a set maximum value. Furthermore, the limitation can be in relation to the outdoor temperature. Typically, the lower the outdoor temperature, the higher the accepted flow / power. When this subtype is used in an ECL Comfort 296 or 310 the flow / energy signal can alternatively come as an M-bus signal.

The frost protection mode maintains a selectable flow temperature, for example 10 °C.

To compensate for the influence of wind, a wind speed sensor can be connected. Based on the wind speed sensor signal (0 - 10 V), the controller can be set to increase the desired flow temperature in relation to increased wind speed.

Unused inputs (from S7 and up) can, by means of an override switch or relay contact, be used for overriding the schedule to a fixed 'Comfort', 'Saving', 'Frost protection' or 'Constant temperature' mode.

An alarm can be activated if the actual flow temperature differs from the desired flow temperature.

Typical A230.1 application:

Operating Guide ECL Comfort 210/296/310, application A230

Cooling (application A230.2):

Typically, the flow temperature is adjusted according to your requirements. The flow temperature sensor S3 is the most important sensor. The desired flow temperature at S3 is set in the

ECL controller. Furthermore, the outdoor temperature (S1) can influence the desired flow temperature. The higher the outdoor temperature, the lower the desired flow temperature.

By means of the week schedule, the cooling circuit can be in

‘Comfort’ or ‘Saving’ mode (two values for the desired flow temperature).

The week schedule also controls two values (‘Comfort’ and

‘Saving’) for the desired room temperature. If the measured room temperature does not equal the desired room temperature, the desired flow temperature can be adjusted.

The motorized control valve M1 is opened gradually when the flow temperature is higher than the desired flow temperature and vice versa.

The return temperature S5 to the cooling supply should not be too low. If so, the desired flow temperature can be adjusted (typically to a higher value), thus resulting in a gradual closing of the motorized control valve.

The circulation pump, P1, is ON at cooling demand.

An external signal for the desired flow temperature can be applied as a 0–10 volt signal to the terminals for S8.

A connected flow or energy meter based on pulses (S7) can limit the flow or energy to a set maximum value.

When the A230.2 is used in an ECL Comfort 296 / 310 the flow / energy signal can alternatively come as an M-bus signal.

The standby mode maintains a selectable flow temperature, for example 30 °C.

Unused inputs (from S7 and up) can, by means of an override switch or relay contact, be used for overriding the schedule to a fixed 'Comfort' or 'Saving' mode.

The temperatures S4 and S6 are used for monitoring purposes only.

The schedule in "Common controller settings" controls the relays

2 and 3. This can be utilized for shifting between two circulation pumps.

See the installation guide, appl. A230.2, ex. d and related electrical connections.

Heating (application A230.3):

This subtype works like A230.1, but the flow - or energy limitation, based on pulse signal is not implemented. If flow - or energy limitation is needed, the M-Bus based signal can be used (ECL

Comfort 296 or 310).

In addition, A230.3 can minimize the risk of dew (condensation).

The RH (Relative Humidity) signal can arrange a minimum desired room temperature for protection against dew (condensation).

Dew can occur when air with high temperature and humidity comes to colder walls, for example in churches, castles and other thick-wall buildings.

The equation -

T.dew = (0.96 x T.room) + (0.25 x RH) - 22.4

is used for calculation of the dew temperature (T.dew).

T.room is the measured room temperature. RH is the Relative

Humidity, based on measured room temperature and humidity.

Room temperature and RH comes either from

• the Remote Control Unit ECA 31 or

• a room temperature sensor and an applied RH signal, 0 - 10

Volt, to S7.

The relationship between applied voltage and related RH value can be set.

An Offset value for the calculated dew temperature (T.dew) can be added for compensation between wall and room temperatures.

Favorite display 1 can show the following:

Heating (A230.4)

This subtype works as subtype A230.1, but the wind influence functionality is not implemented.

In addition, A230.4 can monitor DHW (Domestic Hot Water) temperatures S4 and S6.

An applied voltage signal (0 - 10 Volt) to S8 can be used for:

• pressure measuring. The voltage is converted in the ECL controller to a pressure, measured in bar or

• setting the desired flow temperature. The voltage is converted in the ECL controller to a temperature value.

Operating Guide ECL Comfort 210/296/310, application A230

A230, in general:

Up to two Remote Control Units, ECA 30 / 31, can be connected to one ECL controller in order to control the ECL controller remotely.

Exercise of circulation pumps and control valve in periods without heating or cooling demand can be arranged.

Additional ECL Comfort controllers can be connected via the ECL

485 bus in order to utilize common outdoor temperature signal, time and date signals.

Several ECL controllers, internally connected via ECL 485 bus, work in Master / Slave connection. In a Master / Slave system maximum

2 ECA 30 / 31 can be present.

An unused input can, by means of an override switch, be used to override the schedule to a fixed:

(A230.1, A230.3 and A230.4):

'Comfort', 'Saving', 'Frost protection' or 'Constant temperature' mode

(A230.2):

'Comfort' or 'Saving' mode

Heat-meters:

Up to 5 heat-meters can be connected to the M-bus terminals (ECL

296 / 310).

Data can be transferred to the SCADA system via Modbus and TCP /

IP to the ECL Portal.

Modbus communication to a SCADA system can be established.

The M-bus data (ECL Comfort 296 / 310) can furthermore be transferred to the Modbus communication.

Alarm

A230.1 and A230.3:

Alarm A1 (= relay 4) can be activated if:

• the actual flow temperature differs from the desired flow temperature.

• a temperature sensor or its connection disconnects / short circuits. (See: Common controller settings > System > Raw input overview).

A230.2:

Alarm relay 4 is not used, but a temperature sensor or its connections can be monitored.

(See: Common controller settings > System > Raw input overview).

A230.4:

Alarm A1 (= relay 4) can be activated if:

• the actual flow temperature differs from the desired flow temperature.

• the actual pressure is not inside an acceptable pressure range

• a temperature sensor or its connection disconnects / short circuits. (See: Common controller settings > System > Raw input overview).

Offset adjustment

A measured temperature can be offset adjusted, if needed.

(Navigation: MENU > Common controller > System > Sensor offset)

Input configuration

Inputs (as from S7 and up) which are not part of the application can be configured to be Pt 1000, 0 - 10 Volt, frequency (pulse counter) or Digital input. This feature makes it possible in ECL 296 / 310 to communicate extra signals, such as temperatures, pressures, ON /

OFF conditions, via Modbus and ECL Portal.

The configuration is done by means of the ECL Tool (free software for download) or directly in a dedicated menu in the ECL Portal or the connection for Modbus (BMS / SCADA).

A230, in general (continued):

Application upload

The application upload procedure is the following after having powered up the ECL Comfort controller:

1. Insert the application key

2. Select language

3. Select subtype (the Installation Guide shows subtypes)

4. Set Time and Date

The ECL Comfort controller installs the application, initializes and restarts. Output relays are activated / de-activated (click-sounds from this can be heard). This also means that, for example, circulation pumps can be switched ON and OFF shortly.

Commissioning

When the A230 application has been uploaded the ECL Comfort controller starts in Manual mode. This can be used to verify correct connections of temperature, pressure and flow sensors. Also verifying the controlled components (valve actuators, pumps etc.) for correct functionality can be done.

The application key is delivered with factory settings.

Depending on system type, it might be necessary to change some factory settings individually in order to optimize the functionality.

The application key must be inserted in order to change settings.

Power-down / power-up

When the power supply to the ECL Comfort controller is disconnected (power-down), the output relays go to de-activated position.

This means that, for example, circulation pumps can be switched

ON.

See the electrical connection diagrams in the Installation Guide.

All relay contacts are shown in de-activated situation. Some relay contacts are closed, some relay contacts are open.

When the power supply to the ECL Comfort controller is re-established (power-up), the output relays are activated / de-activated (click-sounds from this can be heard). This also means that, for example, circulation pumps can be switched ON and OFF shortly.

Important:

• Set the correct running time "M run" of the Motorized Control

Valve M1. (Circuit 1 > MENU > Settings > Control parameters

> M run).

The controller is pre-programmed with factory settings that are shown in the ‘Parameter ID overview’ appendix.

2.4 Placing the temperature sensors

2.4.1 Placing the temperature sensors

It is important that the sensors are mounted in the correct position in your system.

The temperature sensor mentioned below are sensors used for the

ECL Comfort 210 / 296 / 310 series which not all will be needed for your application!

Outdoor temperature sensor (ESMT)

The outdoor sensor should be mounted on that side of the building where it is less likely to be exposed to direct sunshine. It should not be placed close to doors, windows or air outlets.

Flow temperature sensor (ESMU, ESM-11 or ESMC)

Place the sensor max. 15 cm from the mixing point. In systems with heat exchanger, Danfoss recommends that the ESMU-type to be inserted into the exchanger flow outlet.

Make sure that the surface of the pipe is clean and even where the sensor is mounted.

Return temperature sensor (ESMU, ESM-11 or ESMC)

The return temperature sensor should always be placed so that it measures a representative return temperature.

Room temperature sensor

(ESM-10, ECA 30 / 31 Remote Control Unit)

Place the room sensor in the room where the temperature is to be controlled. Do not place it on outside walls or close to radiators, windows or doors.

Boiler temperature sensor (ESMU, ESM-11 or ESMC)

Place the sensor according to the boiler manufacturer’s specification.

Air duct temperature sensor (ESMB-12 or ESMU types)

Place the sensor so that it measures a representative temperature.

DHW temperature sensor (ESMU or ESMB-12)

Place the DHW temperature sensor according to the manufacturer’s specification.

Slab temperature sensor (ESMB-12)

Place the sensor in a protection tube in the slab.

ESM-11: Do not move the sensor after it has been fastened in order to avoid damage to the sensor element.

ESM-11, ESMC and ESMB-12: Use heat conducting paste for quick measurement of the temperature.

ESMU and ESMB-12: Using a sensor pocket to protect the sensor will, however, result in a slower temperature measurement.

Operating Guide ECL Comfort 210/296/310, application A230

Language

At application upload, a language must be selected.

If another language than English is selected, the selected language

AND English will be uploaded into the ECL controller.

This makes service easy for English speaking service people, just because the English language menus can be visible by changing the actual set language into English.

(Navigation: MENU > Common controller > System > Language)

If the uploaded language is not suitable, the application must be erased. User and System settings can be saved on the application key before erasing.

After new upload with preferred language, the existing User and

System settings can be uploaded.

2.6.2 ECL Application Key, copying data

General principles

When the controller is connected and operating, you can check and adjust all or some of the basic settings. The new settings can be stored on the Key.

How to update the ECL Application Key after settings have been changed?

All new settings can be stored on the ECL Application Key.

How to store factory setting in the controller from the

Application Key?

Please read the paragraph concerning Application Key, Situation

1: The controller is new from the factory, the ECL Application Key is not inserted.

How to store personal settings from the controller to the Key?

Please read the paragraph concerning Application Key, Situation 3:

A copy of the controllers settings is needed for configuring another controller

As a main rule, the ECL Application Key should always remain in the controller. If the Key is removed, it is not possible to change settings.

Factory settings can always be restored.

Make a note of new settings in the 'Settings overview' table.

Do not remove the ECL Application Key while copying. The data on the ECL Application Key can be damaged!

It is possible to copy settings from one ECL Comfort controller to another controller provided that the two controllers are from the same series (210 or 310).

Furthermore, when the ECL Comfort controller has been uploaded with an application key, minimum version 2.44, it is possible to upload personal settings from application keys, minimum version 2.14.

2.7 Check list

Is the ECL Comfort controller ready for use?

Make sure that the correct power supply is connected to terminals 9 and 10 (230 V or 24 V).

Make sure the correct phase conditions are connected:

230 V: Live = terminal 9 and Neutral = terminal 10

24 V: SP = terminal 9 and SN = terminal 10

Check that the required controlled components (actuator, pump etc.) are connected to the correct terminals.

Check that all sensors / signals are connected to the correct terminals (see 'Electrical connections').

Mount the controller and switch on the power.

Is the ECL Application Key inserted (see 'Inserting the Application Key').

Does the ECL Comfort controller contain an existing application (see 'Inserting the Application Key').

Is the correct language chosen (see 'Language' in 'Common controller settings').

Is the time & date set correctly (see 'Time & Date' in 'Common controller settings').

Is the right application chosen (see 'Identifying the system type').

Check that all settings in the controller (see 'Settings overview') are set or that the factory settings comply with your requirements.

Choose manual operation (see 'Manual control'). Check that valves open and close, and that required controlled components (pump etc.) start and stop when operated manually.

Check that the temperatures / signals shown in the display match the actual connected components.

Having completed the manual operation check, choose controller mode (scheduled, comfort, saving or frost protection).

3.4 Monitoring temperatures and system components

Heating circuit

The overview display in the heating circuit ensures a quick overview of the actual and (desired) temperatures as well as the actual state of the system components.

Display example:

49 °C Flow temperature

(31) Desired flow temperature

24 °C Return temperature

(50) Return temperature limitation

Input overview

Another option to get a quick overview of measured temperatures is the 'Input overview' which is visible in the common controller settings (how to enter the common controller settings, see

‘Introduction to common controller settings’.)

As this overview (see display example) only states the measured actual temperatures, it is read-only.

3.5 Influence overview

This section describes the function in general for the ECL Comfort

210 / 296 / 310 series. The shown displays are typical and not application related. They might differ from the displays in your application.

The menu gives an overview of the influences on the desired flow temperature. It differs from application to application which parameters are listed. It can be helpful in a service situation to explain unexpected conditions or temperatures among others.

If the desired flow temperature is influenced (corrected) by one or more parameters, it is indicated by a small line with arrow-down, arrow-up or double-arrow:

Arrow-down:

The parameter in question reduces the desired flow temperature.

Arrow-up:

The parameter in question increases the desired flow temperature.

Double-arrow:

The parameter in question creates an override (e.g. Holiday).

Straight line:

No active influence.

In the example, the arrow in the symbol points downwards for

'Room lim.'. This means that the actual room temperature is higher than the desired room temperature which again results in a decrease of the desired flow temperature.

Example of overview display with Influence indication:

5.0 Settings

5.1 Introduction to Settings

Descriptions of settings (parameter's functions) are divided into groups as used in the ECL Comfort 210 / 296 / 310 controller's menu structure. Examples: "Flow temperature", "Room limit" and so on. Each group starts with a general explanation.

The descriptions of each parameter are in numeric order, related to the parameter's ID numbers. You might come across differences between the order in this Operating Guide and the ECL Comfort

210 / 296 / 310 controllers.

Some parameter descriptions are related to specific application subtypes. This means that you might not see the related parameter in the actual subtype in the ECL controller.

The note "See Appendix …" refers to the Appendix at the end of this Operating Guide, where parameter's setting ranges and factory settings are listed.

The navigation hints (for example MENU > Settings > Return limit

… ) cover multiple subtypes.

5.2 Flow temperature

The ECL Comfort controller determines and controls the flow temperature related to the outdoor temperature. This relationship is called the heat curve.

The heat curve is set by means of 6 coordinate points. The desired flow temperature is set at 6 pre-defined outdoor temperature values.

The shown value for the heat curve is an average value (slope), based on the actual settings.

When the slope of the heat curve is changed by means of the slope value, the common point for all heat curves will be a desired flow temperature = 24.6 °C at an outdoor temperature = 20 °C and a desired room temperature = 20.0 °C.

Change the coordinates:

Push the dial to enter / change the coordinates of the heat curve

(example: -30,75).

The heat curve represents the desired flow temperatures at different outdoor temperatures and at a desired room temperature of 20 °C.

If the desired room temperature is changed, the desired flow temperature also changes:

(Desired room T - 20) × HC × 2.5

where "HC" is the Heat Curve slope and "2.5" is a constant.

Coordinate changes

The calculated flow temperature can be influenced by the ‘Boost’ and

5.3 Room limit

This section is only relevant if you have installed a room temperature sensor or a Remote Control Unit.

The controller adjusts the desired flow temperature to compensate for the difference between the desired and the actual room temperature.

If the room temperature is higher than the desired value, the desired flow temperature can be reduced.

The 'Infl. -max.' (Influence, max. room temp.) determines how much the desired flow temperature should be reduced.

Use this influence type to avoid a too high room temperature. The controller will allow for free heat gains, i.e. solar radiation etc.

If the room temperature is lower than the desired value, the desired flow temperature can be increased.

The 'Infl. -min.' (Influence, min. room temperature) determines how much the desired flow temperature should be increased.

Use this influence to avoid a too low room temperature.

A typical setting will be -4.0 for 'Infl. -max.' and 4.0 for 'Infl. -min.'

Influence

‘Infl. - min.’ (min. limitation)

Desired room temperature

Actual room temperature

‘Infl. - max.’ (max. limitation)

The ‘Infl. - max.’ and 'Infl. - min.' determine how much the room temperature should influence the desired flow temperature.

If the ‘Infl.’ factor is too high and / or the ‘Adapt. time’ too low, there is a risk of unstable control.

Example 1:

The actual room temperature is 2 degrees too high.

The ‘Infl. - max.’ is set to -4.0.

The ‘Infl. - min.’ is set to 3.0.

Result:

The desired flow temperature is decreased by 2 x -4.0 = 8.0 degrees.

Example 2:

The actual room temperature is 3 degrees too low.

The ‘Infl. - max.’ is set to -4.0.

The ‘Infl. - min.’ is set to 3.0.

Result:

The desired flow temperature is increased by 3 x 3.0 = 9.0 degrees.

5.4 Return limit

A230.1, A230.3, A230.4

The return temperature limitation is based on the outdoor temperature. Typically in district heating systems a higher return temperature is accepted at a decrease in outdoor temperature. The relationship between the return temperature limits and outdoor temperature is set in two coordinates.

The outdoor temperature coordinates are set in 'High T out X1' and 'Low T out X2'. The return temperature coordinates are set in

'High limit Y2' and 'Low limit Y1'.

The controller automatically changes the desired flow temperature to obtain an acceptable return temperature when the return temperature falls below or gets higher than the calculated limit.

This limitation is based on a PI regulation where P ('Infl.' factor) responds quickly to deviations and I ('Adapt. time') responds slower and over time removes the small offsets between the desired and actual values. This is done by changing the desired flow temperature.

5.6 Wind influence

A230.1, A230.3

A wind speed sensor can be connected to the ECL controller in order to increase the desired flow temperature when it is windy outside the building.

The signal from the wind speed sensor is a 0 - 10 volt signal which is applied directly to input S8. The voltage rises at higher wind speeds.

The measured voltage on input S8 must be converted to a wind speed value by the controller. When the wind speed gets higher than the set limit, the controller gradually increases the desired flow temperature to compensate for the higher heat loss from the building.

The following settings set up the scaling and influence.

Parameters indicated with an ID no. like "1x607" mean a universal parameter.

If the wind speed is higher than the set value in ‘Limit’, the desired flow temperature will be increased by the number of degrees per 1 m/s.

See Appendix “Parameter ID overview”

Example:

The wind limit is active at wind speed higher than 10 m/s.

The max. influence is set to 2.0.

The actual wind speed is 2 m/s over limit.

5.8 Control parameters

Control of valve

The motorized control valve is controlled by means of 3-point control or a 0 - 10 volt control signal.

Valve control (heating):

The motorized control valve is opened gradually when the flow temperature is lower than the desired flow temperature and vice versa.

Valve control (cooling):

The motorized control valve is operated oppositely in relation to heating application.

The following explanations for actuator types are related to heating applications.

3-point controlled actuator:

The electric actuator contains a reversible gear-motor. Electric

"open" and "close" signals come from the electronic outputs of the

ECL Comfort controller in order to manage the control valve. The signals are in the ECL Comfort controller expressed as "Arrow-up"

(open) and "Arrow-down" (close) and displayed at the valve symbol.

When the flow temperature (for example at S3) is lower than the desired flow temperature, short open-signals come from the ECL

Comfort controller in order to gradually increase the flow. By this, the flow temperature will align with the desired temperature.

Oppositely, when the flow temperature is higher than the desired flow temperature, short close-signals come from the ECL Comfort controller in order to gradually reduce the flow. Again, the flow temperature aligns with the desired temperature.

Neither open-signals nor close-signals will come as long as the flow temperature corresponds to the desired temperature.

0 - 10 volt controlled actuator

This electric actuator contains a reversible gear-motor. A control voltage between 0 and 10 volt comes from the extension module

ECA 32 in order to manage the control valve. The voltage in the ECL

Comfort controller is expressed as a % value and displayed at the valve symbol. Example: 45 % corresponds to 4.5 volt.

When the flow temperature (for example at S3) is lower than the desired flow temperature, the control voltage is gradually increased in order to gradually increase the flow. By this, the flow temperature will align with the desired temperature.

The control voltage remains on a constant value as long as the flow temperature corresponds to the desired temperature.

Oppositely, when the flow temperature is higher than the desired flow temperature, the control voltage is gradually reduced in order to reduce the flow. Again, the flow temperature aligns with the desired temperature.

VI.LG.H5.02

Operating Guide ECL Comfort 210/296/310, application A230

Thermo-hydraulic actuator, ABV

Danfoss thermo-actuator type ABV is a slow acting valve actuator.

Inside the ABV an electric heat coil will heat a thermostatic element when an electric signal is applied. When heating the thermostatic element it expands in order to manage the control valve.

Two basic types are available: ABV NC (Normal Closed) and ABV NO

(normal open). For example, ABV NC keeps a 2-port control valve closed when no open-signals are applied.

Electric open-signals come from the electronic output of the ECL

Comfort controller in order to manage the control valve. When open-signals are applied to the ABV NC, the valve gradually opens.

Open-signals are in the ECL Comfort controller expressed as

"Arrow-up" (open) and displayed at the valve symbol.

When the flow temperature (for example at S3) is lower than the desired flow temperature, relatively long open-signals come from the ECL Comfort controller in order to increase the flow. By this, the flow temperature will over time be aligned with the desired temperature.

Oppositely, when the flow temperature is higher than the desired flow temperature, relatively short open-signals come from the ECL

Comfort controller in order to reduce the flow. Again, the flow temperature aligns, over time, with the desired temperature.

The control of the Danfoss thermo-actuator type ABV uses a unique designed algorithm and is based on the PWM principle (Pulse

Width Modulation), where the duration of the pulse determines the management of the control valve. The pulses are repeated each 10 sec.

As long as the flow temperature corresponds to the desired temperature, the duration of the open-signals will remain constant.

Set the ‘M run’ according to the examples or measure the running time by means of a stop watch.

How to calculate the running time of a motorized control valve

The running time of the motorized control valve is calculated using the following methods:

Seated valves

Running time = Valve stroke (mm) x actuator speed (sec. / mm)

Example: 5.0 mm x 15 sec. / mm = 75 sec.

Rotating valves

Running time = Turning degrees x actuator speed (sec. / degr.)

Example: 90 degr. x 2 sec. / degr. = 180 sec.

If you want to tune the PI regulation precisely, you can use the following method:

• Set the ‘Tn’ (integration time constant) to its max. value (999 sec.).

• Decrease the value for the ‘Xp’ (proportional band) until the system starts hunting (i.e. gets unstable) with a constant amplitude (it might be necessary to force the system by setting an extreme low value).

• Find the critical time period on the temperature recorder or use a stop watch.

Time

This critical time period will be characteristic for the system, and you can evaluate the settings from this critical period.

‘Tn’ = 0.85 x critical time period

‘Xp’ = 2.2 x proportional band value in the critical time period

If the regulation seems to be too slow, you can decrease the proportional band value by 10%. Make sure there is a consumption when you set the parameters.

5.12 Heat cut-out

MENU > Settings > Heat cut-out

The setting “Summer cut-out” under “Optimization” for the heating circuit in question determines a heating cut-out when the outdoor temperature exceeds the set value.

A filtering constant for calculating the accumulated outdoor temperature is internally set to a value of "250". This filtering constant represents an average building with solid outer and inner walls (bricks).

An option for differentiated cut-out temperatures, based on a set summer period, can be utilized in order to avoid discomfort at falling outdoor temperature. Furthermore, separate filtering constants can be set.

The factory set values for Summer period start and Winter period start are set to same date: May, 20 (Date = 20, Month = 5).

This means:

• "Differentiated cut-out temperatures" are disabled (not active)

• Separate "Filtering constant" values are disabled (not active)

In order to enable differentiated

• cut-out temperature based on summer / winter period

• filtering constants the start dates for the periods must be different.

5.12.2 Summer/winter filter constant

The filter constant of 250 is applicable for average buildings. A filter constant of 1 is close switching according to actual outdoor temperature meaning low filtering (very “light” building).

A filter constant of 300 is then to be chosen if a big filtering is needed (very heavy building).

For heating circuits where the heat cut-out is demanded according to the same outdoor temperature for the whole year, but different filtering is wanted, different dates have to be set in the “Heat cut-out” menu enabling a selection of a filter constant different from the factory setting.

These different values have to be set in both the “Summer” and

“Winter” menu.

The section "Alarm" describes specific application related issues.

Application A230 offers two types of alarms:

Type:

1

1

2

Description:

A230.1, A230.3 and A230.4

Actual flow temperature differs from the desired flow temperature

A230.4

Actual pressure is outside the set pressure range

All subtypes

Disconnection or short-circuiting of a temperature sensor or its connection

Note: A230.2 (cooling application) has no alarm function related to temperatures.

The alarm functions activate the alarm bell symbol.

The alarm functions activate A1 (Relay 4).

The alarm relay can activate a lamp, a horn, an input to an alarm transmitting device etc.

The alarm symbol / relay is activated:

• (type 1) as long as the alarm reason is present (automatic reset).

• (type 2) even if the alarm reason disappears again (manual reset).

Alarm type 1:

If the flow temperature deviates more than the set differences from the desired flow temperature, the alarm symbol / relay will be activated.

If the flow temperature becomes acceptable, the alarm symbol / relay will be de-activated.

If the pressure S8 gets higher than a set value (bar) or gets lower than another set value (bar), the alarm symbol / relay will be activated.

If the pressure becomes acceptable, the alarm symbol / relay will be de-activated.

Alarm type 2:

Selected temperature sensors can be monitored.

Should the connection to the temperature sensor be disconnected, short-circuited or the sensor gets defective, the alarm symbol

/ relay will be activated. In the "Raw input overview" (MENU >

Common controller settings > System > Raw input overview) the sensor in question is marked and the alarm can be reset.

When an alarm is activated, the bell-symbol appears in the right favorite display.

Monitoring and alarm related to connected temperature sensors:

At start-up, the ECL controller detects which temperature sensors are connected.

Should the connection to a temperature sensor be disconnected or short-circuited after start-up, the sensor alarm function can be activated.

This function is helpful at service situations where periodic malfunctions can occur.

The following procedure describes the function:

1.

Go to "Raw input overview" (MENU > Common controller settings > System > Raw input overview).

2.

Place the cursor at the sensor number, which could be suspicious for correct connection and click the dial; a symbol for a magnifying glass appears.

3.

Repeat step 2 if other temperature sensor connections are to be monitored.

4.

The selected temperature sensor(s) is / are now being monitored and you can leave the menu.

5.

Should the connection to the temperature sensor for a short while (more than 3 seconds) be disconnected or short-circuited, the sensor alarm function is activated. An alarm bell symbol appears in the display and the alarm relay is activated.

6.

Verification which sensor connection has activated the alarm:

Go to "Raw input overview" (MENU > Common controller settings > System > Raw input overview).

Look for (by moving the cursor down) the sensor line which is marked with a magnifying glass and a bell-symbol (alarm).

7.

Resetting the alarm:

Mark the line by means of the cursor and click the dial. The symbols for alarm and magnifying glass disappears.

Reset of sensor alarm can also be made in Alarm overview

(MENU > Alarm > Alarm overview: Alarm number 32: T sensor defect). Click the dial and the alarm bell symbol disappears.

The ECL Comfort controllers can be connected via the ECL 485 communication bus to perform a larger system (the ECL 485 communication bus can connect to max. 16 devices).

Each slave must be configured with its own address (1 ... 9).

However, more slaves can have the address 0 if they only have to receive information about outdoor temperature and system time

(listeners).

The total cable length of max. 200 m (all devices incl. the internal ECL

485 communication bus) should not be exceeded.

Cable lengths of more than 200 m may cause noise sensibility (EMC).

In a system with MASTER / SLAVE controllers, only one MASTER controller with address 15 is allowed.

If by mistake more MASTER controllers are present in an ECL 485 communication bus system, decide which controller is to be MASTER.

Change the address in the remaining controllers. However, the system will operate but not be stable with more than one MASTER controller.

In the MASTER controller, the address in ‘ECL 485 addr. (master / slave address)’, ID no. 2048, must always be 15.

7.0 Miscellaneous

7.1 ECA 30 / 31 setup procedures

ECA 30 (code no. 087H3200) is a remote control unit with built-in room temperature sensor.

ECA 31 (code no. 087H3201) is a remote control unit with built-in room temperature sensor and humidity sensor (relative humidity).

An external room temperature sensor can be connected to both types to substitute the built-in sensor.

An external room temperature sensor will be recognized at ECA

30 / 31 power-up.

Connections: See the section 'Electrical connections'.

Max. two ECA 30 / 31 can be connected to one ECL controller or a system (master-slave) consisting of several ECL controllers connected on the same ECL 485 bus. In the master-slave system only one of the ECL controllers is master. The ECA 30 / 31 can, among others, be set to:

• monitor and set the ECL controller remotely

• measure the room temperature and (ECA 31) humidity

• extend comfort / saving period temporarily

After application upload in the ECL Comfort controller, the remote control unit ECA 30 / 31 will after approx. one minute ask to 'Copy application'.

Confirm this in order to upload the application to the ECA 30 / 31.

Menu structure

The menu structure of ECA 30 / 31 is an "ECA MENU" and the ECL menu, copied from the ECL Comfort controller.

The ECA MENU contains:

Part of the ECA 30 / 31 display in ECL mode:

• ECA settings

• ECA system

• ECA factory

ECA settings: Offset adjustment of the measured room temperature.

Offset adjustment of relative humidity (ECA 31 only).

ECA system: Display, communication, override settings and version info.

ECA factory: Erase of all applications in the ECA 30 / 31, restore to factory settings, reset of ECL address and firmware update.

Part of the ECA 30 / 31 display in ECA mode:

If only the "ECA MENU" is shown, it can indicate that the ECA 30 / 31 is not having correct communication address.

See ECA MENU > ECA system > ECA communication: ECL address.

In most cases the ECL address setting must be "15".

Regarding ECA settings:

When ECA 30 / 31 is not used as remote unit, the offset adjustments menu(s) are not present.

7.2 Override function

The ECL 210 / 296 / 310 controllers can receive a signal in order to override the existing schedule. The override signal can be a switch or a relay contact.

Different override modes can be selected, depending on application key type.

Override modes: Comfort, Saving, Constant temperature and Frost protection.

"Comfort" is also called normal heating temperature.

"Saving" can be reduced heating or heating stopped.

"Constant temperature" is a desired flow temperature, set in the menu "Flow temperature".

"Frost protection" stops the heating totally.

Override by means of override switch or relay contact is possible when the ECL 210 / 296 / 310 is in scheduled mode (clock).

Example, override switch connected to S8:

7.3 Several controllers in the same system

When ECL Comfort controllers are interconnected by means of the ECL 485 communication bus (cable type: 2 x twisted pair), the master controller will broadcast the following signals to the slave controllers:

• Outdoor temperature (measured by S1)

• Time and date

• DHW tank heating / charging activity

Furthermore, the master controller can receive information about:

• the desired flow temperature (demand) from slave controllers

• and (as from ECL controller version 1.48) DHW tank heating / charging activity in slave controllers

Situation 1:

SLAVE controllers: How to make use of the outdoor temperature signal sent from the MASTER controller

The slave controllers only receive information about outdoor temperature and date / time.

SLAVE controllers:

Change the factory set address from 15 to address 0.

ECL 485 bus cable

Maximum recommended length of the ECL 485 bus is calculated like this:

Subtract "Total length of all input cables of all ECL controllers in the master - slave system" from 200 m.

Simple example for total length of all input cables, 3 x ECL:

1 x ECL Outdoor temp. sensor: 15 m

3 x ECL Flow temp. sensor: 18 m

3 x ECL Return temp. sensor:

3 x ECL Room temp. sensor:

18 m

30 m

Total: 81 m

Maximum recommended length of the ECL 485 bus:

200 - 81 m = 119 m

In a system with MASTER / SLAVE controllers, only one MASTER controller with address 15 is allowed.

If by mistake more MASTER controllers are present in an ECL 485 communication bus system, decide which controller is to be MASTER.

Change the address in the remaining controllers. However, the system will operate but not be stable with more than one MASTER controller.

In the MASTER controller, the address in ‘ECL 485 addr. (master / slave address)’, ID no. 2048, must always be 15.

Navigation:

• In , go to System > Communication > ECL 485 addr.

SLAVE controllers must be set to another address than 15:

Navigation:

• In , go to System > Communication > ECL 485 addr.

7.4 Frequently asked questions

The definitions apply to the ECL Comfort 210 / 296 / 310 series.

Consequently, you might come across expressions that are not mentioned in your guide.

Circulation pump (heating) does not stop as expected

It is in operation at frost protection (outdoor temperature lower than "P frost T" value) and at heat demand (desired flow temperature higher than "P heat T" value)

The time shown in the display is one hour off?

See ‘Time and Date’.

The time shown in the display is not correct?

The internal clock may have been reset, if there has been a power break for more than 72 hours.

Go to the 'Common controller settings' and 'Time & Date' to set the correct time.

The ECL Application Key is lost?

Switch the power off and on again to see the ECL controller type, version code (e.g. 1.52), code no. and application (e.g.

A266.1) or go to 'Common controller settings' >'Key functions' >

'Application'. The system type (e.g. TYPE A266.1) and the system diagram is displayed.

Order a replacement from your Danfoss representative (e.g. ECL

Application Key A266).

Insert the new ECL Application Key and copy your personal settings from the controller to the new ECL Application Key, if required.

The room temperature is too low?

Make sure that the radiator thermostat does not limit the room temperature.

If you still cannot obtain the desired room temperature by adjusting the radiator thermostats, the flow temperature is too low. Increase the desired room temperature (display with desired room temperature). If this does not help, adjust the ‘Heat curve’

(‘Flow temp.’).

The room temperature is too high during saving periods?

Make sure that the min. flow temperature limitation ('Temp. min.') is not too high.

The temperature is unstable?

Check that the flow temperature sensor is correctly connected and in the right place. Adjust the control parameters ('Control par.').

If the controller has a room temperature signal, see 'Room limit'.

The controller does not operate and the control valve is closed?

Check that the flow temperature sensor is measuring the correct value, see 'Daily use' or 'Input overview'.

Check the influence from other measured temperatures.

How to make an extra comfort period in the schedule?

You can set an additional comfort period by adding new ‘Start’ and ‘Stop’ times in ‘Schedule’.

How to remove a comfort period in the schedule?

You can remove a comfort period by setting start and stop times to the same value.

How to restore your personal settings?

Please read the chapter concerning ‘Inserting the ECL Application

Key’.

158 | © Danfoss | 2019.08

VI.LG.H5.02

Operating Guide ECL Comfort 210/296/310, application A230

How to restore the factory settings?

Please read the chapter concerning ‘Inserting the ECL Application

Key’.

Why can’t the settings be changed?

The ECL Application Key has been removed.

Why can’t an application be selected when inserting the ECL application key into the controller?

The actual application in the ECL Comfort controller must be deleted before a new application (subtype) can be selected.

How to react on alarms?

An alarm indicates that the system is not operating satisfactorily.

Please contact your installer.

What does P and PI control mean?

P control: Proportional control.

By using a P control, the controller will change the flow temperature proportional to the difference between a desired and an actual temperature, e.g. a room temperature.

A P control will always have an offset which not will disappear over time.

PI control: Proportional and Integrating control.

A PI control does the same as a P control, but the offset will disappear over time.

A long ‘Tn’ will give a slow but stable control, and a short ‘Tn’ will result in a fast control but with a higher risk of unstability.

What does the "i" in the upper right corner of the display mean ?

When uploading an application (subtype) from the application key into the ECL Comfort controller, the " i " in the upper right corner indicates that - besides the factory settings - the subtype also contains special user / systems settings.

Why can't the ECL 485 Bus (used in ECL 210 / 296 / 310) and the ECL Bus (used in ECL 100 / 110 / 200 / 300) communicate?

These two communication busses (Danfoss proprietary) are different in connection form, telegram form and speed.

Language

At application upload, a language must be selected.

If another language than English is selected, the selected language

AND English will be uploaded into the ECL controller.

This makes service easy for English speaking service people, just because the English language menus can be visible by changing the actual set language into English.

(Navigation: MENU > Common controller > System > Language)

If the uploaded language is not suitable, the application must be erased. User and System settings can be saved on the application key before erasing.

After new upload with preferred language, the existing User and

System settings can be uploaded.

How to set a correct heat curve?

Short answer:

Set the heat curve to the lowest possible value, but still having comfortable room temperature.

The table shows some recommendations:

House with radiators:

Needed flow temp.

when the outdoor temp. is -10 °C:

Older than 20 years: 65 °C

Recommended heat curve value:

1.4

Between 10 and 20 years old:

Rather new:

60 °C

50 °C

1.2

0.8

Floor heating systems need, in general, a lower heat curve value

Technical answer:

In order to save energy, the flow temperature should be as low as possible, but still considering a comfortable room temperature.

This means the heat curve slope should have a low value.

See the heat curve slope diagram.

Choose the desired flow temperature (vertical axis) for your heating system at the expected lowest outdoor temperature (horizontal axis) for your area. Pick the heat curve closest to the common point of these two values.

Example: Desired flow temperature: 60 (°C) at outdoor temperature:

-10 (°C)

Result: Heat curve slope value = 1.2 (mid-way between 1.4 and 1.0).

In general:

• Smaller radiators in your heating system might require a higher heat curve slope. (Example: Desired flow temperature 70 °C resulting in heat curve = 1.5).

• Floor heating systems require a lower heat curve slope. (Example:

Desired flow temperature 35 °C resulting in heat curve = 0.4).

• Corrections of the heat curve slope should be done in small steps when having outdoor temperatures below 0 °C; one step pr. day.

• If required, adjust the heat curve in the six coordinate points.

• Setting of the desired room temperature has an influence on the desired flow temperature even if a room temperature sensor /

Remote Control Unit is not connected. An example: Increasing the desired room temperature results in a higher flow temperature.

• Typically, the desired room temperature should be adjusted when having outdoor temperatures above 0 °C.

Pressure measuring

Voltage (0 - 10 V) converted to a displayed Pressure (Bar)

(A230.4)

The conversion scale for applied voltage (to terminal S8) into Bar is found:

(Navigation: Circuit 1 > MENU > Alarm > Pressure > Pressure)

Click the Pressure line and the scale diagram appears.

The pressure at 2 Volts and 10 Volts can be set.

In the screen dump to the right the pressure at 2 Volt is 0.0 Bar and at 10 Volt the pressure is 4.0 Bar.

Follow the examples below for setting the pressure values.

Example 1:

The pressure transmitter generates 1 Volt at 0,5 Bar and 8 Volts at 6 Bar.

Relationship between Bar and Volt:

( 6 Bar - 0.5 Bar ) / ( 8 Volt - 1 Volt )

5.5 / 7 = 0.8 Bar / Volt

To get value for Bar at the "2 Volt" point and set into the scale diagram:

0.5 Bar (at 1 Volt) + 0.8 = 1.3 Bar

To get value for Bar at the "10 Volt" point and set into the scale diagram:

6 Bar (at 8 Volt) + (2 x 0.8) = 7.6 Bar

Example 2:

The pressure transmitter generates 0 Volt at 0 Bar and 8 Volts at 5

Bar.

Relationship between Bar and Volt:

( 5 Bar - 0 Bar ) / ( 8 Volt - 0 Volt )

5 / 8 = 0.6 Bar / Volt

To get value for Bar at the "2 Volt" point and set into the scale diagram:

0 Bar (at 0 Volt) + (2 x 0.6) = 1.2 Bar

To get value for Bar at the "10 Volt" point and set into the scale diagram:

5 Bar (at 8 Volt) + (2 x 0.6) = 6.2 Bar

Example 3:

The pressure transmitter generates 4 - 20 mA, being 0 - 6 Bar.

The current, 4 - 20 mA, is directed through a 500 Ohm resistor.

The voltage across the resistor will be 2 Volt at 0 Bar and 10 Volt at 6 Bar.

The values can directly be set in the scale diagram.

Example 4:

The pressure transmitter generates 4 - 20 mA, being 0 - 6 Bar.

The current, 4 - 20 mA, is directed through a 250 Ohm resistor.

The voltage across the resistor will be 1 Volt at 0 Bar and 5 Volt at 6 Bar.

Relationship between Bar and Volt:

( 6 Bar - 0 Bar ) / ( 5 Volt - 1 Volt )

6 / 4 = 1.5 Bar / Volt.

To get value for Bar at the "2 Volt" point and set into the scale diagram:

0 Bar (at 1 Volt) + 1.5 = 1.5 Bar

To get value for Bar at the "10 Volt" point and set into the scale diagram:

6 Bar (at 5 Volt) + (5 x 1,5) = 13.5 Bar

Temperature maintained in the circuits during comfort periods.

Normally during daytime.

Compensation temperature

A measured temperature influencing the flow temperature reference / balance temperature.

Desired flow temperature

Temperature calculated by the controller on basis of the outdoor temperature and influences from the room and / or return temperatures. This temperature is used as a reference for the control.

Desired room temperature

Temperature which is set as the desired room temperature. The temperature can only be controlled by the ECL Comfort controller if a room temperature sensor is installed.

If a sensor is not installed, the set desired room temperature however still influences the flow temperature.

In both cases the room temperature in each room is typically controlled by radiator thermostats / valves.

Desired temperature

Temperature based on a setting or a controller calculation.

Dew point temperature

Temperature at which the humidity in the air condensates.

The controller optimizes the start time of the scheduled temperature periods. Based on the outdoor temperature, the controller automatically calculates when to start in order to reach the comfort temperature at the set time. The lower the outdoor temperature, the earlier the start time.

Outdoor temperature trend

The arrow indicates the tendency, i.e. whether the temperature rises or falls.

Override mode

When ECL Comfort is in Scheduled mode, a switch or contact signal can be applied to an input in order to override to Comfort,

Saving, Frost protection or Constant temperature. As long as the switch or contact signal is applied, the override is active.

Pt 1000 sensor

All sensors used with the ECL Comfort controller are based on the

Pt 1000 type (IEC 751B). The resistance is 1000 ohm at 0 °C and it changes with 3.9 ohm / degree.

Pump control

One circulation pump is working and the other is the spare circulation pump. After a set time, the roles are exchanged.

Refill water function

If the measured pressure in the heating system is too low (e.g.

due to a leakage), water can be supplemented.

Return temperature

The temperature measured in the return influences the desired flow temperature.

Room temperature

Temperature measured by the room temperature sensor or the Remote Control Unit. The room temperature can only be controlled directly if a sensor is installed. The room temperature influences the desired flow temperature.

Room temperature sensor

Temperature sensor placed in the room (reference room, typically the living room) where the temperature is to be controlled.

Saving temperature

Temperature maintained in the heating / DHW circuit during saving temperature periods. Typically, the Saving temperature is lower than the Comfort temperature in order to save energy.

SCADA

Supervisory Control And Data Acquisition. A supervisory system for remote control and monitoring.

Schedule

Schedule for periods with comfort and saving temperatures. The schedule can be made individually for each week day and may consist of up to 3 comfort periods per day.

Software is used in the ECL Comfort controller to do the application related processes.

Weather compensation

Flow temperature control based on the outdoor temperature.

The control is related to a user-defined heat curve.

2-point control

ON / OFF control, e.g. circulation pump, ON / OFF valve, change-over valve or damper control.

3-point control

Actuator positioning by means of Opening, Closing or No-action signals for the motorized control valve in order to control the flow.

No-action means that the actuator remains in its current position.

7.7 Automatic / manual update of firmware

Info:

• Firmware and application software are on the application key

• ECL Comfort has firmware implemented

• Firmware with Encryption has version 2.00 and up

Situation 1:

ECL Comfort controller, new (= no application installed), from before 10 th of July 2018, to be installed:

1. Insert application key.

2. If the firmware on application key is newer than the firmware in the ECL, an update will be done automatically.

3. Hereafter the application can be uploaded.

4. If the firmware in the ECL is newer than the firmware on application key, the application can be uploaded.

Situation 2:

ECL Comfort controller is installed and runs an application.

1. Store all settings on the existing application key *.

2. Erase actual application in the ECL **.

3. Insert an application key with new firmware. The firmware update will be done automatically.

4. When ECL requires language selection, then remove application key.

5. Insert "old" application key.

6. Select language, select application subtype and see an "i" in upper right corner.

7. Set time / date if needed.

8. Choose "Next".

9. In Copy menu, choose YES at System and User settings; then choose "Next".

10. "Old" application is uploaded, ECL restarts and is ready again.

* Navigation: MENU > Common controller settings > Key functions > Copy > "To KEY", System settings = YES, User settings =

YES, Start copying: Push dial.

Within 1 sec the settings are stored on the application key.

** Navigation: MENU > Common controller settings > Key functions > New application > Erase application: Push dial.

NOTE: You might come in a situation where the update will not elapse. This is typically when one or two ECA 30 are connected.

Remedy: Disconnect (remove from its base) the ECA 30. If ECL 310B, then only one ECA 30 should be connected.
