Operating Guide ECL Comfort 310, application P318.21

1.1 Important safety and product information

1.1.1 Important safety and product information

This Operating Guide is associated with the ECL Application Key P318 (code no. 087H3835) and is only focusing on subtype P318.21.

For detailed information about ECL Comfort 310, handling, setting etc., please see the P318 Operating Guide.

P318.21 runs an advanced Domestic Hot Water (DHW) temperature control. As option, a heating circuit can be controlled.

See the Installation Guide for application diagrams and electrical connections.

The application diagrams show mandatory temperature sensors with an underscore; example S3.

The described functions are realized in ECL Comfort 310 which also allows M-bus, Modbus and Ethernet (Internet) communication. The Application Key P318 complies with ECL Comfort 310 controllers as of firmware version 1.11. The firmware (controller software) is visible at start-up of the controller and in 'Common controller settings' in 'System'.

Up to two Remote Control Units, ECA 30 or ECA 31, can be connected.

The application P318.21 works with the additional Internal I/O module ECA 35.

The extension module ECA 35 gives PWM (= Pulse Width Modulation) signal for control valves and ON-OFF signal for Flushing and Heating circuit.

Alternatively, ECA 35 gives 0 - 10 Volt signal for control valves.

The ECL Comfort 310 works with one ECA 35 which is placed in the base part of the ECL Comfort 310.

Together with the ECL Comfort 310 the additional Internal I/O modules can also be used for extra data communication to SCADA:

•Temperature, Pt 1000 (default)

•0 - 10 volt signals

•Digital input

The set-up of input type can be done by means of the Danfoss Software "ECL Tool" or from the ECL Portal.

The ECL Portal (see https://ecl.portal.danfoss.com) is an Internet-based tool for monitoring and remote control of ECL controllers.

Application keys might be released before all display texts are translated. In this case the text is in English.

Safety Note

To avoid injury of persons and damages to the device, it is absolutely necessary to read and observe these instructions carefully.

Necessary assembly, start-up, and maintenance work must be performed by qualified and authorized personnel only.

Local legislations must be respected. This comprises also cable dimensions and type of isolation (double isolated at 230 V).

A fuse for the ECL Comfort installation is max. 10 A typically.

The ambient temperature ranges for ECL Comfort in operation are:

ECL Comfort 210 / 310: 0 - 55 °C

ECL Comfort 296: 0 - 45 °C.

Exceeding the temperature range can result in malfunctions.

Installation must be avoided if there is a risk for condensation (dew).

The warning sign is used to emphasize special conditions that should be taken into consideration.

This symbol indicates that this particular piece of information should be read with special attention.

Operating Guide ECL Comfort 310, application P318.21

Automatic update of controller software (firmware):

The software of the controller is updated automatically when the key is inserted (as of controller version 1.11 (ECL 210 / 310) and version 1.58 (ECL 296)). The following animation will be shown when the software is being updated:

Progress bar

During update:

•Do not remove the KEY

If the key is removed before the hour-glass is shown, you have to start afresh.

•Do not disconnect the power

If the power is interrupted when the hour-glass is shown, the controller will not work.

•Manual update of controller software (firmware):

See the section "Automatic / manual update of firmware"

As this Operating Guide covers several system types, special system settings will be marked with a system type. All system types are shown in the chapter: 'Identifying your system type'.

°C (degrees Celsius) is a measured temperature value whereas K (Kelvin) often is used for temperature differences.

The ID no. is unique for the selected parameter.

Example	First digit	Second digit	Last three digits

11174	1	1	174

	-	Circuit 1	Parameter no.
		Circuit 1	Parameter no.


12174	1	2	174

	-	Circuit 2	Parameter no.
		Circuit 2	Parameter no.

If an ID description is mentioned more than once, it means that there are special settings for one or more system types. It will be marked with the system type in question (e.g. 12174 - A266.9).

2.0 Installation

2.1 Before you start

Description, in general

Subtype P318.21 ex. a

Control of the flow temperature in an indirectly heated DHW (Domestic Hot Water) system. The temperature sensor S3 must be connected and the temperature control is, among others, based on the flow signal from flow meter F1. This flow is present when DHW is taken from the tap. The control valve is operated by a stepper motor via the V1 output, which is a PWM signal. With control by means of a stepper motor ( = quick operating), the control valve controls the flow for correct temperature at S3.

The measured temperature at S2 can change the Xp value (proportional band) for optimum DHW temperature control. Return temperature S5 is for monitoring only.

A Bypass function can maintain a desired temperature at S2. This helps to reduce the heat-up time for DHW if DHW has not been taken from the tap for a longer time.

Based on the measured temperature at S2, the control valve V1 can be opened periodically to a set position. ECL awaits the temperature to reach a set temperature and V1 closes again. A

schedule ("Schedule, bypass") can be set for having Bypass active in set periods.

A flush function, activating an ON-OFF valve via output X1, can avoid the heat exchanger to be too warm when no DHW is taken from the tap.

Subtype P318.21 ex. b

In addition to the description of example a, the subtype can furthermore control a heating circuit.

The ON-OFF valve X3 (= solenoid valve = magnetic valve) is operated by either the X3 output or the V2 output, which is the PWM signal for control of a stepper motor. In this case the stepper motor either fully opens or closes the X3 valve.

The week schedule ("Schedule") determines the periods (Comfort) where the heating circuit is switched in.

A room thermostat, potential free ( = volt free ) connected at input S11, can also switch in the heating if "Schedule" is in Saving mode. The heating circuit is switched off (= closed) during DHW heating.
