2.0 Installation

2.1 Before you start

The applications (subtypes) in the A377 application key are very flexible and almost identical.

However, some applications have extra functions which are described separately.

These are the basic principles:

Typical A377.1 application, example a:

S 1 ECL 310

S 4

Heating (circuit 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).

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

By means of a week schedule (up to 3 ‘Comfort’ periods / day), the heating circuit can be in ‘Comfort’ or ‘Saving’ mode (two different temperature values for the desired room temperature).

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

The motorized control valve M2 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. Furthermore, the return temperature limitation can be dependent on the outdoor temperature.

Typically, the lower the outdoor temperature, the higher the accepted return temperature.

The shown diagram is a fundamental and simplified example and does not contain all components that are necessary in a system.

All named components are connected to the ECL Comfort controller.

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

If the measured room temperature (Remote control unit ECA 30 /

31) does not equal the desired room temperature, the desired flow temperature can be adjusted.

The circulation pump (P2) 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 M-bus signal 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.

The desired flow temperature of heating circuit 1 can, via S7, be controlled by means of an external voltage in the range 0-10 volt.

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

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

The room temperature signal can be achieved from the Remote

Control Unit ECA 30 / 31, if connected.

A377.2:

When both DHW heating / charging and heating circuit 1 are active, the circulation pump in the heating circuit can continue operating. The heating circuit temperature is typically increased.

This is parallel mode. If the increase of the flow temperature cannot be accepted, the circulation pump in heating circuit can be stopped. This is DHW priority mode.

Heating circuit, in general:

Exercise of circulation pump and control valve in periods without heating demand can be arranged.

Heating (circuit 2):

This circuit works after same principles as circuit 1.

The flow temperature sensor S4 is the most important sensor.

The motorized control valve M3 controls the circuit.

The return temperature (S2) enables limitation as described previously.

Heating circuit 2 can be connected after heating circuit 1. If so, the desired flow temperature at S3 can be influenced by the desired flow temperature at S4.

DHW (circuit 3):

The DHW heating circuit is connected directly to the heating source. The temperature sensor S10 measures the return temperature. If the return temperature limit is exceeded, the desired temperature at S9 can be corrected.

By means of a week schedule (up to 3 ‘Comfort’ periods / day), the

DHW circuit can be in ‘Comfort’ or ‘Saving’ mode (two different temperature values for desired DHW temperature).

Charging start, DHW tank with 1 or 2 temperature sensors

When the measured DHW temperature S6 gets lower than the charging-start temperature, the DHW heating pump P1 is switched

ON.

The motorized control valve (M1) is controlled in order to maintain the heating / charging temperature at S9.

The DHW charging pump is switched ON when the S9 temperature is acceptable, which means it must be within 3 K from desired heating / charging temperature. See also application A377.1, ex. d.

If S9 is placed on the heat-exchanger's secondary side, it must be placed in the heat-exchanger.

The DHW charging temperature is determined by the desired DHW temperature at S6 plus the set charging difference. The charging temperature is typically 5–10 degrees higher than the desired

DHW temperature.

A377.1, A377.3:

S10 can have one of two functions:

1. Act as return temperature limiter

2. Monitor the DHW heating temperature in order to avoid discharging and enable return temperature limitation.

Function 1: The return temperature, when the DHW heating / charging is active, can be limited to a set value.

Function 2: The DHW charging pump is switched ON when the S10 temperature is higher than the DHW temperature. After 4 minutes, the return temperature limitation (set value) is activated.

A377.2:

The DHW heating / charging circuit is connected after heating circuit 1. The DHW heating circuit cannot be connected directly to the heating source. The temperature demand at S9 is transferred as desired temperature at S3.

The DHW heating circuit has a preheating circuit, where the DHW heating temperature at S9 is adapted to the desired DHW charging temperature at S10. If the DHW charging temperature at S10 cannot be reached, the ECL controller gradually increases the desired DHW heating temperature at S9 in order to obtain the DHW charging temperature. The ECL controller remembers the adapted

S9 temperature. A maximum temperature value can be set.

A delayed start of charging pump can be arranged. Also, it can be arranged, that the start of the charging pump depends on the charging temperature. In this case, S10 must be placed in the heat-exchanger.

Charging stop, DHW tank with 1 temperature sensor:

When the measured DHW temperature S6 gets higher than the charging-stop temperature, the DHW charging pump P2 is switched OFF. A post-run time can be set.

Charging stop, DHW tank with 2 temperature sensors:

When the measured DHW temperature S6 gets 2 K higher than the charging-start temperature AND the lower tank temperature

S8 gets higher than the charging-stop temperature, the DHW charging pump P2 is switched OFF. A post-run time can be set.

DHW circulation:

In charging applications the DHW circulation can be through the DHW tank (connection A) or through the heat-exchanger

(connection B).

The solution with connection A results in closing of the motorized control valve after the DHW tank charging procedure.

The solution with connection B stops the DHW charging pump after the DHW tank charging procedure. The temperature at the charging temperature sensor is maintained according to the value of the desired DHW temperature in order to compensate for the heat loss in the DHW circulation pipe.

Flow / power limitation

A connected flow or energy meter based on M-bus signal can limit the flow or power to a set maximum value.

An anti-bacteria function is available for activation on selected days of the week.

The DHW circulation pump P3 has a week schedule for up to 3

ON-periods per day.

A377, in general

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

When the DHW circuit is active for the heating / charging procedure, heating circuits 1 and 2 can be closed in order to give higher priority to the DHW heating / charging.

Holiday programs are present for Heating and DHW circuits.

Besides, a holiday program is present for the entire controller.

One or more connected flow or energy meters (based on M-bus signal) can limit the flow or power to a set maximum (DHW circuit) and in relation to the outdoor temperature (heating circuits).

Input S7 can be used to control the desired flow temperature of heating circuit 1. The applied voltage in the range 0 - 10 volt is converted in the ECL controller to the desired flow temperature.

Exercise of circulation pumps and control valve in periods without heating 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. The ECL controllers in the ECL 485 system can work in master-slave system.

Unused input can, by means of an override switch, be used to override the schedule to a fixed 'Comfort', 'Saving', 'Frost protection' or 'Constant temperature' mode.

Modbus communication to a SCADA system can be established.

The M-bus data can furthermore be transferred to the Modbus communication.

Alarm:

Alarm A1 (= relay 6) can be activated:

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

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

When the A377 has been uploaded, the ECL Comfort controller starts in Manual mode. This can be used for checking the controlled components for correct functionality.

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.

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, 296 or 310).

The “Key overview” does not inform — through ECA 30 / 31 — about the subtypes of the application key.

Key inserted / not inserted, description:

ECL Comfort 210 / 310, controller versions lower than 1.36:

-

-

Take out the application key; for 20 minutes settings can be changed.

Power up the controller without the application key inserted; for 20 minutes settings can be changed.

ECL Comfort 210 / 296 / 310, controller versions 1.36 and up:

-

-

Take out the application key; for 20 minutes settings can be changed.

Power up the controller without the application key inserted; settings cannot be changed.

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

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.

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

DHW circuit

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

Display example (heat exchanger):

50 °C Flow temperature

(50)

- -

Desired flow temperature

(30)

Return temperature: sensor not connected

Return temperature limitation

Display example with heat exchanger:

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.

Danfoss District Energy VI.GU.F4.02

DEN-SMT/DK 57

Operating Guide ECL Comfort 310, application A377

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:

58 DEN-SMT/DK VI.GU.F4.02

Danfoss District Energy

Operating Guide ECL Comfort 310, application A377

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 Installation Guide and the ECL Comfort

210 / 296 / 310 controllers.

You might also come across navigation hints which are not present in your application.

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

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

… ) cover multiple subtypes.

Some parameter descriptions refer to Duct or Flow or Inlet temperature because the parameters in question are used in other applications too.

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.

The heat curve can be changed in two ways:

1. The value of the slope is changed (see heat curve examples on next page)

2. The coordinates of the heat curve are changed

Change the value of the slope:

Push the dial to enter / change the slope value of the heat curve

(example: 1.0).

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

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

‘Ramp’ functions etc.

External signal for desired flow temperature

A voltage (0 - 10 V) can be applied to the input terminal S7 in order to determine the desired flow temperature.

The measured voltage on input S7 must be converted to a temperature value by the controller. When the voltage gets higher, the desired flow temperature increases.

5.3 Room limit

The following section is a general description for Room temperature limitation.

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

In the following description is referred to "flow temperature" in general.

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 or heat from a fire place 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 type to avoid a too low room temperature.

This could for example be caused by windy surroundings.

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

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

5.4 Return limit

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.

5.5 Flow / power limit

Heating circuit

A flow or energy meter can be connected (M-bus signal) to the ECL controller in order to limit the flow or consumed power.

The flow / power limitation can be based on the outdoor temperature. Typically, in district heating systems a higher flow or power is accepted at lower outdoor temperatures.

The relationship between the flow or power limits and the outdoor temperature is set in two coordinates.

5.7 Control parameters

Control of valves

The motorized control valves are controlled by means of 3-point control signal.

Valve control:

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

The water flow through the control valve is managed by means of an electric actuator. The combination "actuator" and "control valve" is also called motorized control valve. The actuator can in this way gradually increase or decrease the flow in order to change the supplied energy. Different types of actuators are available.

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.

Danfoss District Energy VI.GU.F4.02

DEN-SMT/DK 89

Operating Guide ECL Comfort 310, application A377

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.

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.

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

5.9 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.

5.9.2 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.

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.

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).

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

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.

Situation 1:

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

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.

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 system type and the software generation of the controller 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’.

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.

148 DEN-SMT/DK VI.GU.F4.02

Danfoss District Energy

Operating Guide ECL Comfort 310, application A377

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.

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

Between 10 and 20 years old:

Rather new:

60 °C

50 °C

Recommended heat curve value:

1.4

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.

2.2 2.6 3.0 3.4

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.

7.5 Definitions

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

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

Accumulated temperature value

A filtered (dampened) value, typically for room and outdoor temperatures. Is calculated in the ECL controller and is used to express the heat stored in the walls of the house. The accumulated value does not change so rapidly as the actual temperature.

Air duct temperature

Temperature measured in the air duct where the temperature is to be controlled.

Alarm function

Based on the alarm settings, the controller can activate an output.

Anti-bacteria function

For a defined period, the DHW temperature is increased in order to neutralize dangerous bacteria, e.g. Legionella.

Balance temperature

This setpoint is the basis for the flow / air duct temperature. The balance temperature can be adjusted by the room temperature, the compensation temperature and the return temperature. The balance temperature is only active if a room temperature sensor is connected.

BMS

Building Management System. A supervisory system for remote control and monitoring.

Comfort operation

Normal temperature in the system controlled by the schedule.

During heating the flow temperature in the system is higher to maintain the desired room temperature. During cooling the flow temperature in the system is lower to maintain the desired room temperature.

Comfort temperature

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.
