2.0 Installation

2.1 Before you start

The 14 different applications P330.1 ...P330.14 are heating and DHW applications in various combinations.

The basic principles for a heating circuit

(example referring to P330.1)

Typically, the flow temperature is adjusted according to your requirements.

The flow temperature sensor S3 is the most important sensor. The desired flow temperature at S3 is calculated in the ECL controller, based on the outdoor temperature (S1) and the desired room temperature. The lower the outdoor temperature, the higher the desired flow temperature.

By means of a week schedule (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). The motorized control valve M1 is opened gradually when the flow temperature is lower than the desired flow temperature and vice versa.

The return temperature (S5) can be limited, for example not to be too high. If so, the desired flow temperature at S3 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. In boiler-based heating supply the return temperature should not be too low (same adjustment procedure as above).

A flow / power limitation can be arranged by using an M-bus based signal from a flow / heat meter. Furthermore, the limitation can be in relation to the outdoor temperature.

If the measured room temperature, S13 or via the remote control unit ECA 30 does not equal the desired room temperature, the desired flow temperature can be adjusted.

General information:

In’ Saving’ mode the heating can be reduced or totally switched off. The ‘Frost protection’ mode maintains a selectable flow temperature, for example 10 °C.

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.

The desired flow temperature of heating circuit 1 can, via S8, be controlled by means of an external voltage in the range 0-10 volt.

Exercise of circulation pump and control valve can be arranged.

Application P330.1:

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 basic principles for a DHW circuit, type 1

(example referring to P330.4)

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 the desired DHW temperature at S10).

The DHW heating temperature sensor S9 is the most important sensor. If the measured DHW temperature (S10) gets lower than the desired DHW temperature, the DHW heating pump (P7) is switched ON. The motorized control valve (M3) is controlled in order to maintain the DHW heating temperature at S9. The DHW heating temperature is determined by the desired DHW temperature at S10 plus the charging difference. When the DHW heating temperature is reached, the DHW charging pump P5 is switched ON. The DHW heating temperature at S9 is typically 5–10 degrees higher than the desired DHW temperature.

DHW tank with 1 temperature sensor (S10):

When the measured DHW temperature (S10) gets higher than the desired DHW temperature, the DHW heating pump (P7) and the DHW charging pump (P5) are switched OFF. The post-run time can be set individually.

DHW tank with 2 temperature sensors (S10, upper and S2, lower):

If the measured DHW temperature (S10) gets higher than the desired DHW temperature and the temperature (at S2) gets higher than the cut-out temperature, the DHW heating pump (P7) and the DHW charging pump (P5) are switched OFF. The post-run time can be set individually.

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 is used to compensate for the heat loss in the DHW circulation pipe. Furthermore, after DHW tank charging, the DHW heating temperature (at S9) is controlled according to the desired DHW temperature.

The return temperature (S7) can be limited, for example not to be too high. If so, the desired flow temperature at S9 can be adjusted (typically to a lower value), thus resulting in a gradual closing of the motorized control valve. In boiler-based heating supply the return temperature should not be too low (same adjustment procedure as above).

A flow / power limitation can be arranged by using an M-bus based signal from a flow / heat meter.

General information:

The ‘Frost protection’ mode maintains a selectable temperature, for example 10 °C.

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

The outdoor temperature sensor S1 is used to protect the circulation circuit against frost.

The DHW circulation pump (P8) has a week schedule for up to 3 ON periods per day.

The basic principles for a DHW circuit, type 2

(example referring to P330.5)

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 the desired DHW temperature at S10).

When the measured DHW temperature (S10) gets lower than the desired DHW temperature, the DHW heating pump (P7) and the DHW charging pump (P5) are switched ON.

DHW tank with 1 temperature sensor (S10):

DHW tank with 2 temperature sensors (S10, upper and S2, lower):

When the measured DHW temperature (S10) gets higher than the desired DHW temperature and the temperature (at S2) gets higher than the cut-out temperature, the DHW heating pump (P7) and the DHW charging pump (P5) are switched OFF. The post-run time can be set individually.

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 is used to compensate for the heat loss in the DHW circulation pipe. After DHW tank charging, the DHW charging pump P5 stops. The heating pump P7 continues being switched ON.

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

The outdoor temperature sensor S1 is used to protect the circulation circuit against frost.

The DHW circulation pump (P8) has a week schedule for up to 3 ON periods per day.

The basic principles for the master circuit

(example referring to P330.10)

The desired flow temperature at S3 is adjusted according to the demand from the sub-circuits (heating and DHW circuits). The flow temperature sensor S3 is the most important sensor.

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

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

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

The basic principles for the master circuit with buffer

(example referring to P330.14)

The highest demand from the sub-circuits (heating and DHW circuits) plus a difference ('Demand offset') determine the desired buffer tank temperature at S11.

When the measured buffer tank temperature (S11) gets lower than the desired buffer tank temperature, the charging pump (P1) is switched ON.

The motorized control valve (M1) is controlled in order to maintain the buffer tank heating temperature at S3. The motorized control valve is opened gradually when the flow temperature is lower than the desired flow temperature and vice versa.

The flow temperature sensor S3 is the most important sensor.

The desired temperature at S3 is determined by the desired buffer tank temperature at S11 plus a charging temperature difference. The buffer tank heating temperature at S3 is typically 5–10 degrees higher than the desired buffer tank temperature.

Buffer tank with 1 temperature sensor (S11):

When the measured buffer tank temperature (S11) gets higher than the desired buffer tank temperature, the charging pump (P1) is switched OFF. The post-run time can be set.

Buffer tank with 2 temperature sensors (S11, upper and S12, lower):

When the measured upper buffer tank temperature (S11) gets higher than the desired buffer tank temperature and the measured lower buffer tank temperature (S12) gets higher than the cut-out temperature, the charging pump (P1) is switched OFF. The post-run time can be set.

If S12 is not connected, S11 will be used for ON and OFF control of the charging pump.

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

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

When the measured buffer temperature (S11) gets higher than the desired buffer temperature, the desired temperature at S3 is lowered to typically 10 °C. Hereafter the charging pump (P1) is switched OFF. The post-run time can be set.

Operating Guide ECL Comfort 310, application P330

Application P330.14:

In order to avoid a discharging of the DHW circuit (a higher DHW temperature goes to a lower buffer tank temperature) two parameters can be set:

*The parameter ("Tank start diff.", ID no 13192) determines an acceptable temperature difference between S10 and S11 in order to start the DHW charging.

*The parameter ("Tank stop diff.", ID no 13196) determines an acceptable temperature drop of the difference between S10 and S11 in order to stop the DHW charging.

General information:

The desired flow temperature of the master circuit can, via S8, be controlled by means of an external voltage in the range 0-10 volt.

Operating Guide ECL Comfort 310, application P330

Application P330.1 – P330.5:

Heating circuits 2, 3, 4 and DHW circuits can be connected after heating circuit 1. Circuit 1 acts as master and can react on the sub-circuits demand. If so, the desired flow temperature at S3 can be influenced by the desired flow temperature at S4, S9, S10 and DHW charging temperature respectively.

The desired flow temperature of heating circuit 1 can, via S8, be controlled by means of an external voltage in the range 0 - 10 volt.

Application P330.6 – P330.15:

Heating circuits and DHW circuits are typically connected after the master controlled circuit (M). When so, the desired flow temperature at S3 can be influenced by the desired flow temperature at S4, S9, S10 and DHW charging temperatures.

The desired flow temperature of the master circuit can, via S8, be controlled by means of an external voltage in the range 0 - 10 volt.

Application P330 in general:

Up to two Remote Control Units, the ECA 30 (one for each heating circuit) 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 during the charging procedure, selected heating circuits can be closed in order to give higher priority to the DHW charging.

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

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

Input S8 can be used to control the desired flow temperature of heating circuit 1 or the master circuit. The applied voltage signal in the range 0-10 volt is converted in the ECL controller to the desired flow temperature.

Modbus communication to a SCADA system can be established. The M-bus data can furthermore be transferred to the Modbus communication.

Alarm relay (R6) 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).

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