2.0 Installation

2.1 Before you start

The Application Key A214 contains several applications, mainly related to ventilation systems with heating or cooling or a combination of these. The applications in the A214 key offer a wide range of possibilities (see the examples).

The application A214.1 is very flexible. These are the basic principles:

Cooling with room temperature control:

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

Comfort controller as the 'Desired balance temperature'.

The motorized control valve M2 (controlling the cooling transfer) is opened gradually when the duct temperature is higher than the desired duct temperature and vice versa.

S 4

Room temperature:

If the measured room temperature (S4 or ECA 30) does not equal the desired room temperature, the desired temperature at S3 can be adjusted.

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

The desired room temperature determines a correction of the desired temperature at S3.

If the room temperature is not measured, the desired room temperature equals (will be) the desired temperature at S3. In this case, the setting of the 'Balance temperature' is not considered (or: has no influence).

The fan (F1) is ON / OFF controlled according to the schedule and cooling demand. The damper (P2) is ON / OFF controlled according to schedule. The circulation pump (X3) is ON / OFF controlled according to cooling demand.

Return temperature (optional):

If the measured return temperature (S5) does not equal the limitation value (typically, the return temperature becomes lower than the limitation value), the desired temperature at S3 can be adjusted (typically to a higher value). This results in a gradual closing of the motorized control valve.

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.

The applications A214.2 and A214.3 are very flexible and almost identical. These are the basic principles:

A214.2: Heating with duct temperature control

A214.3: Heating with room temperature control

Typically, the heating temperature is adjusted according to your requirements. The temperature sensor S3 is the most important sensor. The desired temperature at S3 is set in the ECL Comfort controller as the 'Desired balance temperature'.

The motorized control valve M1 (controlling the heating supply temperature) is opened gradually when the S3 temperature is lower than the desired S3 temperature and vice versa.

S4 temperature:

If the measured S4 temperature does not equal the desired S4 temperature, the desired temperature at S3 can be adjusted.

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 desired S4 temperature). The desired S4 temperature determines a correction of the desired temperature at S3.

The fan (F1) is ON / OFF controlled according to the schedule and heating demand. The damper (P2) is ON / OFF controlled according to schedule. The circulation pump (X3) is ON / OFF controlled according to heating demand.

The application A214.4 is very flexible. These are the basic principles:

Heating / cooling with air duct temperature control

Typically, the heating / cooling temperature is adjusted according to your requirements.

The flow temperature sensor S3 in the heating circuit is the most important sensor. The desired temperature at S3 is set in the ECL

Comfort controller as the 'Desired balance temperature'.

The motorized control valve M1 (controlling the heating temperature) is opened gradually when the flow temperature is lower than the desired balance temperature and vice versa.

At cooling, the motorized control valve M2 controls the cooling temperature at S4.

Air duct temperature:

A too low air duct temperature S4 will activate the heating circuit

M1, whereas a too high air duct temperature will activate the cooling circuit M2.

At heating demand, the air duct temperature S4 can adjust the desired temperature at S3. At cooling demand, the air duct temperature S4 is controlled according to the desired air duct temperature. A "Dead zone" (= number of degrees) can be set in order to avoid unstable shifts between heating and cooling operation.

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

In 'Saving' mode the desired air duct temperature determines a correction of the desired temperature at S3 in heating mode. In cooling mode the cooling is OFF during 'Saving'.

The fan F1 is ON / OFF controlled according to the schedule and heating / cooling demand. The damper P2 is ON / OFF controlled according to schedule. The circulation pump X3 is ON / OFF controlled according to heating demand.

For a description of alarms, compensation temperature, return temperature limitation (S5) and frost protection (S6 and S7), please read the section ‘A214 and A314 in general’.

The application A314.1 is very flexible. These are the basic principles:

Heating and (passive) cooling with air duct temperature control

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

Comfort controller as the 'Desired balance temperature'.

The motorized control valve M1 (controlling the heating temperature) is opened gradually when the flow temperature is lower than the desired temperature and vice versa. At cooling, the motorized damper M2 controls the cooling temperature. The cooling section can be passive (re-circulation) or active.

Air duct temperature:

A too low temperature at S4 will activate the heating circuit (M1), whereas a too high duct temperature will activate the cooling circuit (M2).

At heating demand, the temperature at S4 can adjust the desired temperature at S3. At cooling demand, the S4 temperature is controlled according to the desired S4 temperature. A "Dead zone"

(= number of degrees) can be set in order to avoid unstable shifts between heating and cooling operation.

M1 is 3-point controlled, whereas M2 is 0-10 V controlled.

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

In 'Saving' mode the desired air duct temperature determines a correction of the desired temperature at S3 in heating mode. In cooling mode the cooling is OFF during 'Saving'.

The fan F1 is ON / OFF controlled according to the schedule and heating / cooling demand. The damper P2 is ON / OFF controlled according to schedule. The circulation pump X3 is ON / OFF controlled according to heating demand.

The advanced heating application A314.4 is very flexible. These are the basic principles:

Heating with room temperature and air pressure control

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

Comfort controller as the 'Desired inlet temperature'.

The recovery circuit, controlled by M2, is considered as the main circuit, whereas the heating circuit, controlled by M1, is the supplementary circuit.

The motorized control valve M1 (controlling the heating temperature) is opened gradually when the S3 temperature is lower than the desired S3 temperature and vice versa.

Typical A314.4 application:

Room temperature:

If the room temperature (S4 or ECA 30) does not equal the desired room temperature, the desired temperature at S3 can be adjusted.

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 desired inlet temperature and two different temperature values for desired room temperature).

The fan F1 is ON / OFF controlled according to the schedule and heating demand. A damper P2 can be ON / OFF controlled according to schedule. The circulation pump X3 is ON / OFF controlled according to heating demand.

Air pressure control:

The fans V2 and V3 are speed controlled individually in relation to desired pressures (Pascal) at S11 and S12. The signals at S11 and

S12 are measured as 0 - 10 volt and converted into Pascal in the ECL

Comfort 310. Furthermore, the speed of the fans can be lowered at lower outdoor temperatures in order to reduce cold air inlet.

Heat recovery:

In order to utilize heat from the exit air duct, a rotating heat-exchanger, a cross heat-exchanger or a fluid battery can be controlled by M2. Based on the outdoor temperature S1, the entry duct temperature S13 and the exit duct temperature S14 the recovery efficiency (in %) can be indicated.

Night cooling:

During Saving mode a passive cooling (setting the fans ON) can be arranged, mainly under the following conditions:

• room temperature is higher than desired saving room temperature outdoor temperature is lower than the room temperature

Room temperature:

If the room temperature (S4 or ECA 30) does not equal the desired room temperature, the desired temperature at S3 can be adjusted.

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 desired inlet temperature and two different temperature values for desired room temperature).

The fan F1 is ON / OFF controlled according to the schedule and heating demand. A damper P2 can be ON / OFF controlled according to schedule. The circulation pump X3 is ON / OFF controlled according to heating demand.

Air quality control (CO

When the ppm value (0 - 10 volt signal measured by S11) exceeds a selectable limit, the damper M2 gradually opens in order to supply more fresh air.

When M2 is fully open, the fans V2 and V3 are gradually increased in speed until the ppm value is acceptable. Speed relation between

V2 and V3 can be set.

As an alternative, the S11 signal can express an RH signal (Relative

Humidity).

A214 and A314 in general:

Compensation temperature (optional):

If the measured compensation temperature (S1 or S2) is higher or lower than the limitation value, the desired temperature at S3 can be adjusted. The compensation temperature can be measured by the outdoor temperature sensor or for example an additional room temperature sensor.

Override possibilities:

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

Alarm functions:

The alarm (relay 4 in ECL 210, relay 6 in ECL 310) is activated:

1. If an unaccepted deviation between the desired and actual S3 temperature occurs.

2. If a frost thermostat (S7) is activated.

3. If a frost temperature is detected at S5 or S6.

4. If the fire alarm (S8) is activated.

5. If a temperature sensor or its connection disconnects / short circuits.

A214.2, A214.3, A214.4, A214.5, A314.1, A314.2 and A314.3:

Return temperature (optional):

If the measured return temperature (S5) does not equal the limitation value (typically, the return temperature becomes higher than the limitation value), the desired temperature at S3 can be adjusted (typically to a lower value). This results in a gradual closing of the motorized control valve.

Frost protection (optional):

Temperature sensor S6 and / or frost thermostat S7 can protect the heat exchanger against frost.

Furthermore, if the S5 temperature becomes too low, it also can enable the frost protection.

An activated frost protection will start the alarm, stop the fan F1, close the damper P2 and fully open the motorized control valve M1.

Fire alarm (optional):

An activated fire alarm input will start the alarm, stop the fan F1, close the damper P2 and close the motorized control valves.

2.2 Identifying the system type

Sketch your application

The ECL Comfort controller series is designed for a wide range of heating, domestic hot-water (DHW) and cooling systems with different configurations and capacities. If your system differs from the diagrams shown here, you may want to make a sketch of the system about to be installed. This makes it easier to use the Installation Guide, which will guide you step-by-step from installation to final adjustments before the end-user takes over.

The ECL Comfort controller is a universal controller that can be used for various systems. Based on the shown standard systems, it is possible to configure additional systems. In this chapter you find the most frequently used systems. If your system is not quite as shown below, find the diagram which has the best resemblance with your system and make your own combinations.

The circulation pump(s) in heating circuit(s) can be placed in the flow as well as the return. Place the pump according to the manufacturer’s specification.

2.3 Mounting

2.3.1 Mounting the ECL Comfort controller

For easy access, you should mount the ECL Comfort controller near the system. Select one of the following methods using the same base part (code no. 087H3230):

• Mounting on a wall

• Mounting on a DIN rail (35 mm)

The ECL Comfort 310 can only be mounted in the ECL Comfort

310 base part.

Screws, PG cable glands and rawlplugs are not supplied.

Locking the ECL Comfort controller

In order to fasten the ECL Comfort controller to its base part, secure the controller with the locking pin.

56 DEN-SMT/DK

To prevent injuries to persons or the controller, the controller has to be securely locked into the base. For this purpose, press the locking pin into the base until a click is heard and the controller no longer can be removed from the base.

If the controller is not securely locked into the base part, there is a risk that the controller during operation can unlock from the base and the base with terminals (and also the 230 V a.c. connections) are exposed.

To prevent injuries to persons, always make sure that the controller is securely locked into its base. If this is not the case, the controller should not be operated!

The easy way to lock the controller to its base or unlock it is to use a screw driver as lever.

2.4 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 and 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 or 310).

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

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).

3.2 Understanding the controller display

This section describes the function in general for the ECL Comfort

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

Choosing a favorite display

Your favorite display is the display you have chosen as the default display. The favorite display will give you a quick overview of the temperatures or units that you want to monitor in general.

If the dial has not been activated for 20 min., the controller will revert to the overview display you have chosen as favorite.

To shift between displays: Turn the dial until you reach the display selector ( ) at the bottom right side of the display. Push the dial and turn to choose your favorite overview display. Push the dial again.

Heating circuit

Overview display 1 informs about: actual outdoor temperature, controller mode, actual room temperature, desired room temperature.

Overview display 2 informs about: actual outdoor temperature, trend in outdoor temperature, controller mode, max. and min. outdoor temperatures since midnight as well as desired room temperature.

Overview display 1: Overview display 2:

Overview display 3 informs about: date, actual outdoor temperature, controller mode, time, desired room temperature as well as shows the comfort schedule of the current day.

Overview display 4 informs about: state of the controlled components, actual flow temperature,

(desired flow temperature), controller mode, return temperature

(limitation value), influence on desired flow temperature.

Dependent on the chosen display, the overview displays for the heating circuit inform you about:

• actual outdoor temperature (-0.5)

• controller mode ( )

• actual room temperature (24.5)

• desired room temperature (20.7 °C)

• trend in outdoor temperature ( )

• min. and max. outdoor temperatures since midnight ( )

• date (23.02.2010)

• time (7:43)

• comfort schedule of the current day (0 - 12 - 24)

• state of the controlled components (M2, P2)

• actual flow temperature (49 °C), (desired flow temperature (31))

• return temperature (24 °C) (limitation temperature (50))

Overview display 3:

Example of overview display with

Influence indication:

Overview display 4:

The setting of the desired room temperature is important even if a room temperature sensor / Remote Control Unit is not connected.

If the temperature value is displayed as

"- -" the sensor in question is not connected.

"- - -" the sensor connection is short-circuited.

Setting the desired temperature

Depending on the chosen circuit and mode, it is possible to enter all daily settings directly from the overview displays (see also the next page concerning symbols).

Setting the desired room temperature

The desired room temperature can easily be adjusted in the overview displays for the heating circuit.

Action: Purpose:

Desired room temperature

Confirm

Adjust the desired room temperature

Confirm

Examples:

20.5

This overview display informs about outdoor temperature, actual room temperature as well as desired room temperature.

The display example is for comfort mode. If you want to change the desired room temperature for saving mode, choose the mode selector and select saving.

The setting of the desired room temperature is important even if a room temperature sensor / Remote Control Unit is not connected.

Setting the desired room temperature, ECA 30 / ECA 31

The desired room temperature can be set exactly as in the controller. However, other symbols can be present in the display

(please see 'What do the symbols mean?').

With the ECA 30 / ECA 31 you can override the desired room temperature set in the controller temporarily by means of the override functions:

3.4 Monitoring temperatures and system components

This section describes the function in general for the ECL Comfort

210 / 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

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.

This section describes the function in general for the ECL Comfort

210 / 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.

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 / 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 / 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.

5.3 Duct T limit / Room limit

This section is only relevant if you have installed a duct / room temperature sensor S4 or a Remote Control Unit for utilizing the room temperature signal.

In the following description is referred to "flow temperature" in general. This can be air duct or inlet temperature too.

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

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

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

Use this influence type to avoid a too high duct / room temperature.

The controller will allow for free heat gains, i.e. solar radiation or heat from a fire place etc.

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

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

Use this influence type to avoid a too low duct / room temperature.

This could e.g. 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

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

x stands for circuit / parameter group.

The return temperature limitation is based on a selectable temperature value. The controller automatically changes the desired flow / duct temperature to obtain an acceptable return temperature when the return temperature falls below or gets higher than the set 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 / duct temperature.

Typical for heating systems is that the return temperature must be as low as possible.

Typical for cooling systems is that the return temperature must be as high as possible.

5.6 Compensation 1

A limit value for the compensation temperature makes it possible to change the desired flow / duct temperature.

The influence from the compensation temperature can result in an increase or a decrease desired flow / duct temperature. The compensation temperature is often the outdoor temperature but could for example be a room temperature.

This application contains 2 compensation temperature limits:

Compensation 1 (Comp. 1) and Compensation 2 (Comp. 2).

In the parameter descriptions "Sx"is used for the compensation temperature.

A214.1 - A214.6 and A314.1 - A314.3:

The desired flow / duct temperature can be influenced by a compensation temperature, measured by S1 or S2. The choice between S1 and S2 is made by the parameter "Comp. T select".

A314.4 - A314.7 and A314.9:

The desired flow / duct temperature can be influenced by a compensation temperature, measured by one of the temperature sensors S1 . . . S16.

Combination of two compensation temperature limit points:

Compensation 1 and 2 can be combined to give a compensation at

2 different compensation temperatures. This can for instance be used to avoid a too big difference between the indoor and outdoor temperatures.

The example below shows that below Comp. 1 and above Comp.

2, the desired flow / duct temperature will be increased, but with different values.

Example :

Comp. 1 value is set to 21 °C and Comp. 2 value is set to 25 °C.

'Infl. min.' for Comp. 2 is set to 0.0 and 'Infl. max.' for Comp. 2 is set to 1.5.

The desired flow / duct temperature is kept on a constant level as long as the compensation temperature is between 21 and 25

5.8 Control parameters

Control of valves / dampers / cross- / rotating heat-exchangers

/ fluid batteries

The motorized control valves / dampers are controlled by means of either 3-point control or a 0 - 10 volt control signal or a mix of these.

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.

Damper control (typical M2):

The motorized controlled damper(s) is(are) opened gradually when the air duct temperature is lower than the desired duct temperature and vice versa.

The air flow through the damper(s) is managed by means of an electric actuator.

Rotating heat-exchanger, cross heat-exchanger or fluid battery

(typical M2):

In order to utilize the heat of the exit air different devices can be controlled.

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.

130 DEN-SMT/DK VI.GU.A2.02

Danfoss District Energy

Installation Guide ECL Comfort 210 / 310, application A214 / A314

0 - 10 volt controlled actuator or damper (ECL Comfort 310):

This actuator type is indicated in the application diagrams with an "A". 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.

A314.1 and A314.2: The 0 - 10 volt output signal can be reversed.

Control of fan speed

The fans V2 and V3 can be individually speed controlled by means of 0 - 10 volt signals. Each speed control signal comes from the analog outputs of the ECA 32 module.

The control voltage is expressed as a % value and displayed at the

V1 and V2 symbols.

Danfoss District Energy VI.GU.A2.02

DEN-SMT/DK 131

Installation Guide ECL Comfort 210 / 310, application A214 / A314

Control of fan speed

A314.3:

The fan speed is controlled in relation to measured wind speed

(S10). When the wind speed gets higher, the control voltage is gradually increased in order to increase the speed of the fan V1.

A314.4 and A314.6:

The desired pressures (Pascal) at S11 and S12 can be set individually in relation to the outdoor temperature (S1).

When the pressure gets lower than the desired pressure, the control voltage is gradually increased in order to increase the speed of the fan more than the moment before. By this, the pressure difference aligns with the desired pressure. A too high pressure results in opposite procedure.

The control voltage remains on a fixed value as long as the pressure corresponds to the desired pressure.

The desired pressure can be limited to a maximum and a minimum pressure value.

The control voltage can be limited to a maximum and a minimum

% value.

When the ECL controller is in Saving mode:.

• the fan velocity of V2 is controlled in relation to a desired pressure at S11

• V3 is OFF

The pressures at S11 and S12 are measured in Pascal and represented as a 0 - 10 volt signal. Conversion of the 0 - 10 volt signal into pressure is done in a conversion (scale) menu. Two different voltages (X1 and X2) and the related pressure values can be set.

A314.5, A314.7 and A314.9:

The limitation value for air quality (ppm) at S11 can be set.

When the air quality (ppm) gets higher than the set limit, the control voltage is gradually increased in order to increase the speed of the fan(s). Fan V3 is speed controlled by means of an off-set in relation to fan V2.

The control voltage can be limited to a maximum and a minimum

% value.

When the ECL controller is in Saving mode:

• the fan velocity of V2 can be controlled in relation to a desired pressure at S11

• V3 is OFF

The air quality at S11 is measured in ppm and represented as a 0 - 10 volt signal. The higher ppm value, the less air quality.

Conversion of the 0 - 10 volt signal into ppm is done in a conversion

(scale) menu. Two different voltages (X1 and X2) and the related ppm values can be set.

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.)

The pressure is measured by means of a 0 - 10 volt signal.

The measured voltage must be converted to a pressure value by the controller.

The following procedure sets up the conversion:

Push the dial to see the graph and enter the value sets for the 2 input voltages and related pressure values.

Pressure value range: 0 … 1999 pascal

The factory set voltage values can be changed in the two separate menus "X1" and "X2".

Typically, the higher the voltage, the higher the displayed pressure.

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.

Temp.

Critical time period

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.

A314.3:

Wind influence on fan speed

A wind speed sensor can be connected to the ECL controller in order to control the fan speed. Typically, the more windy, the higher the fan speed.

The signal from the wind speed sensor is a 0-10 volt signal which is applied directly to input S10. The voltage rises at higher wind speed.

The measured voltage on input S10 must be converted to a wind speed value by the controller.

The following procedure sets up the scaling.

The measured and converted wind speed signal controls the output signal 'Control voltage'. Typically, the higher the wind speed, the higher the 'control voltage' for the fan speed.

Push the dial to see the graph and enter the value sets for the wind speed values (0 and 10 m/s) and control voltage.

Control voltage: 0.0 ... 10.0 V

Fixed wind speed settings: 0 (zero) m/s and 10 m/s.

The section "Application" describes specific application related issues.

"Total stop" (ID 1x021) works differently, depending on actual subtype. In relation to the parameter "Fan function" (ID 11137), selected subtype and controller mode, different functionalities are present. See the related tables.

"Stop at T out" (ID 1x038) is used for the "Night cooling" function.

Outdoor temperature must be higher than set value in order to activate "Night cooling".

"Comp. T select" (ID 1x140) is a universal parameter:

A214.1 - A214.6 and A314.1 - A314.3:

The desired flow / duct temperature can be influenced by a compensation temperature, measured by S1 or S2. The choice between S1 and S2 is made by the parameter "Comp. T select".

A314.4 - A314.7 and A314.9:

The desired flow / duct temperature can be influenced by a compensation temperature, measured by one of the temperature sensors S1 . . . S16.

The choice of compensation sensor is made by the parameter

"Comp. T select".

"Summer, cut-out" (ID 1x179) is present in A314.4 and A314.5.

When outdoor temperature gets higher than cut-out value + 0.5 K, the heating is stopped.

Falling outdoor temperature: When actual - and "accumulated outdoor temperature" come below cut-out value - 0.5 K, the heating will start. The time constant for "accumulated outdoor temperature" is a fixed value and corresponds to an average building's time constant.

The parameter 'Stop difference' (ID 1x194) is used differently, depending on application:

A214.6: When X3 is set to act as room thermostat.

A314.4 … A314.7: When utilizing the "Night cooling" function.

The room temperature must be "Stop difference" higher than the outdoor temperature for enabling "Night cooling".

"S4 filter" is present in the subtypes A214.2, A214.4 and A314.1.

"1. step level" and "2. step level" are used for smooth transition between recovery stage and heating / cooling stage.

"Send desired T" (ID 1x500) is present in some of the subtypes.

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

When the controller acts as a slave controller in a master / slave system, information about the desired flow temperature can be sent to the master controller via the ECL 485 bus.

*

* See Appendix “Parameter ID overview”

OFF:

Information about the desired flow temperature is not sent to the master controller.

ON:

Information about the desired flow temperature is sent to the master controller.

In the master controller, 'Demand offset' must be set to a value in order to react on a desired flow temperature from a slave controller.

When the controller acts as a slave, its address must be 1, 2, 3 ... 9 in order to send the desired temperature to the master (see the section

‘Miscellaneous’, ‘Several controllers in the same system’).

5.11 Alarm

Many applications in the ECL Comfort 210 and 310 series have an alarm function. The alarm function activates relay 4

(A214 applications in ECL Comfort 210 or 310) or relay 6 (A314 applications in ECL Comfort 310).

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

Typical alarms, type 1:

• S3 defective

• Actual S3 temperature differs from the desired S3 temperature

• Fire alarm (S8)

• Filter monitor S10 (Digital 10)

• Heat recovery

• Activation of a frost thermostat (S7)

• Detection of frost temperature at S5 or S6

Type 1 alarms are present as long as the alarm reason is present.

Typical alarms, type 2:

• Fan monitor S9 (Digital 9)

• Inlet pressure

• Outlet pressure

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

Type 2 alarms are present even if the alarm reason no longer is present. To remove the alarm indications, the alarms must be cleared.

When an alarm is activated, the appears in the favorite displays.

To find the reason for alarm:

• select MENU

• select ‘Alarm’

• select ‘Alarm overview’. A will be shown at the alarm in question.

Some alarms are generated if a measured value gets higher or lower than set values.

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

2. Comfort 7 - 23

3. Saving

4. Frost protection

Example 1:

Circuit 1:

Holiday set to "Saving"

Common Controller:

Holiday set to "Comfort"

Result:

As long as "Comfort" is active in Common Controller, circuit 1 will be in

"Comfort".

Example 2:

Circuit 1:

Holiday set to "Comfort"

Common Controller:

Holiday set to "Saving"

Result:

As long as "Comfort" is active in circuit 1, it will be in "Comfort".

Example 3:

Circuit 1:

Holiday set to "Frost protection"

Common Controller:

Holiday set to "Saving"

Result:

As long as "Saving" is active in Common Controller, circuit 1 will be in "Saving".

The ECA 30 / 31 cannot override the holiday schedule of the controller temporarily.

However, it is possible to make use of the following options from the ECA 30 / 31 when the controller is in scheduled mode:

Day off

Controlled components Circuit selector

"Manual control" has higher priority than "Output override".

When the selected controlled component (output) is not ‘AUTO’, the

ECL Comfort controller does not control the component in question

(pump or motorized control valve e.g.). Frost protection is not active.

When output override of a controlled component is active the symbol

! ’ is shown to the right of the mode indicator in the enduser displays.

Valves (M), dampers (M) and Fans (V) are in some applications controlled by a 0–10 volt (0–100 %) signal. The control can be set to

AUTO or ON.

AUTO: Normal control (0–100%).

ON: The 0–10 volt signal is set to the %-value, set below the indication

'ON'.

6.8.5 Energy meter (heat-meter) and M-bus, general information

ECL 310 only

When using the Application Key in the ECL Comfort 310 / 310B, up to 5 energy meters (heat-meters) can be connected to the M-bus connections.

Connection of energy meter can:

• limit the flow

• limit the power

• transfer energy meter data to the ECL Portal, via Ethernet, and / or a SCADA system, via Modbus.

Energy meter data acquisition from ECL Portal is possible without setting up the M-bus configuration.

Many applications with control of heating, DHW or cooling circuit have the possibility to react on energy meter data.

To verify if actual application key can be set to react on energy meter data:

See Circuit > MENU > Settings > Flow / power.

The ECL Comfort 310 can always be used for monitoring purpose of up to 5 energy meters.

The ECL Comfort 310 acts as an M-bus master and must be set to communicate with connected energy meter(s).

See MENU > Common controller > System > M-bus config.

Technical info:

• The M-bus data are based on standard EN-1434.

• Danfoss recommends AC supplied energy meters in order to avoid battery draining.

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.

7.3 Frequently asked questions

The definitions apply to the Comfort 210 as well as ECL Comfort

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.

DEN-SMT/DK 197

Installation Guide ECL Comfort 210 / 310, application A214 / A314

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.

7.4 Definitions

The definitions apply to the Comfort 210 as well as ECL Comfort

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

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.

Dew point temperature

Temperature at which the humidity in the air condensates.

DHW circuit

The circuit for heating the domestic hot water (DHW).

Duct temperature

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

ECL Portal

A supervisory system for remote control and monitoring, locally and via Internet.

EMS

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

Factory settings

Settings stored on the ECL Application Key to simplify the set up of your controller the first time.

Flow temperature

Temperature measured in the water flow where the temperature is to be controlled.

Flow temperature reference

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.

Heat curve

A curve showing the relationship between actual outdoor temperature and desired flow temperature.

Heating circuit

The circuit for heating the room / building.

Holiday schedule

Selected days can be programmed to be in comfort, saving or frost protection mode. Besides this, a day schedule with comfort period from 07.00 to 23.00 can be selected.

Humidity, relative

This value (stated in %) refers to the indoor moisture content compared to the max. moisture content. The relative humidity is measured by the ECA 31 and is used for the calculation of the dew point temperature.

Inlet temperature

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

Limitation temperature

Temperature that influences the desired flow / balance temperature.

Log function

The temperature history is displayed.

Master / slave

Two or more controllers are interconnected on the same bus, the master sends out e.g. time, date and outdoor temperature.

The slave receives data from master and sends e.g. desired flow temperature value.

Modulating control (0 - 10 V control)

Positioning (by means of a 0 - 10 V control signal) of the actuator for the motorized control valve in order to control the flow.

Optimization

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.

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
