2.0 Installation

2.1 Before you start

The ECL application key P318 contains 4 subtypes, P318.1, P318.2,

P318.10 and P318.11.

The basic principles for application P318.1:

Temperature control of DHW buffer

The desired DHW temperature at S6 (set in circuit 1, favorite display 1) determines the buffer charging procedure. The buffer temperature sensors S6 and S8, the supply temperature sensor S2 and the charging temperature sensor S3 are the most important sensors and must be connected. If one of the mentioned temperature sensors is not connected, the control valve M1 will close; alternatively, the control pump P1 / V1 will stop.

The charging temperature at S3 is based on the desired DHW temperature at S6 and a set charging difference.

The application allows internal or external DHW circulation. When connected for external circulation, the desired S3 temperature is the same as the desired DHW temperature, when charging is not in progress.

Optional: Temperature control of the circulation pipe at S9 ensures the desired temperature by means of ON / OFF control of pump P3 or speed control of pump V3. During the charging process the circulation pump can be switched OFF or run at a minimum speed.

Start buffer charging process:

1.Buffer temperature S6 temperature gets lower than ('Desired DHW temperature' + 'Start difference').

An example: 60 °C + (-5) = 55 °C

2.X1 is switched ON

3.M1 opens either fully or to a preset position (alternatively, P1 / V1 is switched ON / preset speed) in order to increase the supply temperature S2. Return temperature limitation is respected.

4.P2 / V2 is switched ON when supply temperature S2 gets higher than ('Desired DHW temperature' + 'Pump start diff.').

An example: 60 °C + 3 K = 63 °C

V2 starts with minimum speed, for example 20 %.

5.M1 (or P1 / V1) controls the charging temperature at S3.

6.V2 increases the speed as long as the charging temperature S3 is higher than (desired charging temperature - 2 K).

Stop buffer charging process:

1.Buffer temperature S6 temperature gets higher than (2 K + 'Desired DHW temperature' + 'Start difference)

AND

Lower buffer temperature S8 gets higher than ('Desired DHW temperature' + 'Stop difference).

An example: S6 temperature higher than (2 + 60 °C + (-5) = 57 °C) AND (60 °C + (-8) = 52 °C)

2.P2 is switched OFF, respecting 'Char. P post-run'. V2 changes to 0 %.

NOTE: Post-run is not respected if charging temperature S3 is lower than desired charging temperature.

3.X1 is switched OFF.

4.M1 closes (alternatively, P1 / V1 stops) or maintains the desired temperature at S3.

Operating Guide ECL Comfort 310, application P318

By means of a week schedule, the DHW circulation can be ON / OFF controlled.

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

Alternatively, the control pump P1 / V1 is increased in speed when the charging temperature is lower than the desired charging temperature and vice versa.

The return temperature S5 can be limited, for example not to be too high. If so, the desired charging temperature at S3 can be adjusted (typically to a lower value); this results in a gradual closing of the motorized control valve or, alternatively, a lower speed of the control pump.

DHW circulation temperature control:

If DHW circulation return temperature sensor S9 is not connected, the ON-OFF controlled pump will be ON. A speed controlled pump can be limited to a desired speed by means of V.out max. and V.out min settings.

The ON-OFF output X1 is ON at DHW heating demand.

As an option, the desired DHW temperature at S6 can be set externally. A voltage signal (1 - 10 Volt) can be applied to input S12 (ECA 32 / 35). The scale for voltage versus temperature can be set.

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

The anti-bacteria function can be set to include the DHW circulation.

The ON-OFF output X2 is ON at active anti-bacteria function.

The basic principles for application P318.2:

DHW temperature and buffer control

If the measured DHW temperature S4 is lower than the desired DHW temperature (set in circuit 1, favorite display 1), the motorized control valve M2 opens gradually for more water from the buffer tank.

Cold tap water is, via the heat-exchanger, used to control the DHW temperature S4 if the temperature gets higher and will gradually close the control valve M2.

The DHW temperature sensor S4, the charging temperature sensor S3, the supply temperature sensor S2 and the buffer temperature sensors S6 and S8 are the most important sensors and must be connected. If one of the mentioned temperature sensors is not connected, the control valve M1 will close; alternatively, the control pump P1 / V1 will stop.

The buffer charging temperature at S3 is based on the set desired buffer temperature at S6 (set in circuit 2, favorite display 1).

Optional: Temperature control of the circulation pipe at S9 ensures the desired temperature by means of ON / OFF control of pump P3 or speed control of pump V3.

Start buffer charging process:

1.Buffer temperature S6 temperature gets lower than ('Desired charging temperature' + 'Start difference').

An example: 70 °C + (-5) = 65 °C

2.X1 is switched ON

3.M1 opens (alternatively, P1 / V1 is switched ON / preset speed) in order to increase the supply temperature

S2. Return temperature limitation is respected.

4.P2 / V2 is switched ON when supply temperature S2 gets higher than ('Desired charging temperature' + 'Pump start diff.').

An example: 70 °C + 3 K = 73 °C

V2 starts with minimum speed, for example 20 %.

5.M1 (or P1 / V1) controls the charging temperature at S3.

6.V2 increases the speed as long as the charging temperature S3 is higher than (desired charging temperature - 2 K).

Stop buffer charging process:

1.Buffer temperature S6 temperature gets higher than (2 K + 'Desired charging temperature' + 'Start difference)

AND

Lower buffer temperature S8 gets higher than ('Desired DHW temperature' + 'Stop difference).

An example: S6 temperature higher than (2 + 70 °C + (-5) = 67 °C)

AND S8 temperature higher than (70 °C + (-8) = 62 °C).

2.P2 is switched OFF, respecting 'DHW P post-run'. V2 changes to 0 %.

NOTE: Post-run is not respected if charging temperature S3 is lower than desired charging temperature.

3.X1 is switched OFF.

4.M1 closes (alternatively, P1 / V1 stops).

The basic principles for application P318.10:

Temperature control of DHW

The desired DHW temperature at S3 (set in circuit 1, favorite display 1) determines the temperature control.

The DHW flow temperature sensor S3 is the most important sensor and must be connected. If S3 is not connected, the control valve M1 will close; alternatively, the control pump P1 / V1 will stop.

Temperature control of the DHW circulation pipe at S9 ensures the desired temperature by means of speed control of pump P3 / V3.

A week schedule for switching the DHW circulation pump ON and OFF can be set.

If DHW circulation return temperature sensor S9 is not connected, the ON-OFF controlled pump will be ON regardless the schedule status.

A speed-controlled pump can be limited to a desired speed by means of V.out max. and V.out min settings.

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

Alternatively, the control pump P1 / V1 is increased in speed when the DHW flow temperature is lower than the desired DHW flow temperature and vice versa.

The return temperature S5 can be limited, for example not to be too high. If so, the desired DHW temperature at S3 can be adjusted (typically to a lower value); this results in a gradual closing of the motorized control valve or, alternatively, a lower speed of the control pump.

The supply temperature S2 is used to compensate the proportional band Xp in order to improve the temperature control at different supply temperatures.

The water flow signal from F1 can be used to override the control valve in order to optimize the DHW temperature control. This pro-active functionality compensates for the delay before the flow temperature sensor S3 measures a change in temperature.

The water flow signal can also be utilized for control of the S3 temperature, even if there is no DHW circulation.

As an option, the desired DHW temperature can be set externally. A voltage signal (1 - 10 Volt) can be applied to input S12 (ECA 32 / 35). The scale for voltage versus temperature can be set.

An anti-bacteria function for the DHW circuit is available for activation on selected days of the week. The anti-bacteria function can be set to include the DHW circulation.

The ON-OFF output X2 is ON when anti-bacteria function is active.

The basic principles for application P318.11:

Advanced DHW temperature and buffer control

The desired DHW temperature at S3 (set in circuit 1, favorite display 1) determines the temperature control.

The DHW flow temperature sensor S3, the buffer temperature sensors S6 and S8 are the most important sensors and must be connected. If S3 is not connected, the control pump P1 / V1 will stop; alternatively, the control valve M1 (examples c and d) will close.

Temperature control of the DHW circulation pipe at S9 ensures the desired temperature by means of speed control of pump P3 / V3. A week schedule for switching the DHW circulation pump ON and OFF can be set.

If DHW circulation return temperature sensor S9 is not connected, the ON-OFF controlled pump will be ON regardless the schedule status.

A speed-controlled pump can be limited to a desired speed by means of V.out max. and V.out min settings.

The control pump P1 / V1 is increased in speed when the DHW flow temperature is lower than the desired DHW flow temperature and vice versa.

Alternatively, the motorized control valve M1 (examples c and d) is opened gradually when the DHW flow temperature is lower than the desired DHW temperature and vice versa.

The buffer is ON / OFF controlled by means of P2 or M2, operating as ON / OFF valve, based on 3-point control.

Start buffer charging process:

1.Buffer temperature S6 temperature gets lower than ('Desired DHW temperature' + 'Start difference').

An example: 60 °C + 5) = 65 °C

2.X1 is switched ON

3.P2 is switched ON

Stop buffer charging process:

1.Buffer temperature S6 temperature gets higher than (2 K + 'Desired DHW temperature' + 'Start difference)

AND

Lower buffer temperature S8 gets higher than ('Desired DHW temperature' + 'Stop difference).

Return water from DHW heat-exchanger to buffer can be directed by the change-over valve X3, based on temperature relationship between S5 and S8.

This return layering function directs low temperature water to buffer-bottom or higher temperature water to buffer-mid. Differential temperatures for layering control can be set.

The supply temperature S2 is used to compensate the proportional band Xp for improving the temperature control at different supply temperatures.

The water flow signal from F1 can be used to override the control valve for optimizing the DHW temperature control. This pro-active functionality compensates for the delay before the flow temperature sensor S3 measures a change in temperature.

P318, in general

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

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 bus system can work as master and slaves. The application P318 can work alone or as a slave.

Heat-meters:

Up to 5 heat-meters can be connected to the M-bus terminals. Data can be transferred to the SCADA system via Modbus and TCP / IP to the ECL Portal.

The P318 application has event indications for

•Charging temperature

•Tank (buffer) temperature

•DHW flow temperature

•Supply temperature

•Anti-bacteria

Typically, an event is registered if a set temperature condition is not accepted. The events can be prioritized to be indicated as information or an alarm.

The alarm A1 (= relay 6) can be activated if:

•an event occurs

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

VI.JM.Q5.02

Operating Guide ECL Comfort 310, application P318

PWM (Pulse Width Modulation)

A 200 Hz frequency is applied to the PWM controlled pump. The duty cycle (the percentage of the period time) determines the pump speed.

Pump speed, PWM or 0 – 10 Volt controlled

Some types of speed controlled pumps are limited to a minimum speed, for example 30 % (PWM or 3.0 Volt). Even if the applied control % gets lower than 30 %, the pump speed remains on the minimum level *.

Furthermore, when the applied control % gets below, for example, 10 %, the pump switches OFF. In order to get the pump switched ON again, the applied control % must exceed 20 %.

This behavior can, at low load or a too big pump, cause unstable temperature regulation. To avoid this, the P318 has a function where the applied control signal is converted into a pulsed signal. The pump is shortly stopped and then started again. The result is a pump speed control also below the minimum speed level.

The parameters "PWM period" (ID 11565) and "Adapt time" (ID 11065) are used for this functionality.

*) See the pump manufacturer's data sheet

Input configuration

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

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

Commissioning

When the P318 application has been uploaded, the ECL Comfort 310 controller starts in Manual mode. This can be used to verify correct connections of input related components, for example temperature and pressure sensors and flow meters.

In addition, controlled components can be verified for correct functionality.

The application key is delivered with factory settings. Depending on system type, it is recommended to change some of the settings individually for optimizing the functionality.

These setting changes, if required, are listed after the explanation of each subtype (See section "Before you start")

Important:

Set the correct running time "M run" of Motorized Control Valve(s) (Circuit X > MENU > Settings > Control parameters > M run).

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

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

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 Operating 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.

See the Installation Guide (delivered with the application key) for application types / sub-types.

Advice for settings:

Factory settings in the subtypes are related to the examples a. Some of the application examples need change of dedicated settings.

Locking the ECL Comfort 210 / 310 controller

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

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!
