Please disregard the descriptions of any parameters not available in your specific system setup. Page Optimizer [Hours] Figure 4. Page 49 Service Settings Pre-heat period This is the function that allows the controller to calculate the optimum starting time.
If the system is equipped with a room temperature sensor, this function is adaptive. If no room temperature sensor is connected, the controller estimates the room tem- perature as a function of the actual outdoor temperature and the default pre-heat pe- riod entered by the operator see below.
Page 50 Service Settings Pre-heat method This function enables the controller to determine the flow temperature level during the pre-heat period. The purpose is to reach comfort room temperature sooner, that is, re- duce the duration of the pre-heat period. Page 52 Flow cut-off Depending on the type of ECL and the type of application you have selected, it is possible to customize 1 or more sensor inputs see page If one of these inputs is used to measure the water flow, the controller can be set up to close the valve if the flow in the system falls below a user-defined limit.
Flow temp. The follow- ing parameters can be set: Display text Parameter Default value, Page Limiter Service Settings Room influence These settings determine how the room temperature should influence flow tempera- ture control.
They are only applicable when a room sensor is connected in the heat circuit. Page 55 Service Settings Flow This and the following functions Energy, Wind, Sun and Universal are related to the sensors you connect to those inputs that can be customized after you have selected an application for the controller see page The Flow function requires that the flow in the heat circuit is being measured. It en- ables the controller to change the flow temperature if the current flow in the circuit exceeds the flow setpoint.
Page 56 This function is ex- tremely flexible and is used for very special applications. Page Hot-Water Circuit Functions This section describes all parameters that can be set for a hot-water circuit. Please dis- regard the descriptions of any parameters not available in your specific system setup. Anti-bacteria function When this function is active, the hot-water temperature is raised once in a hour period to a user-defined temperature and for a user-defined length of time.
The con- troller accomplishes this by temporarily raising the hot-water temperature setpoint. Page 59 Service Settings Charging temperature These settings control how the water in a hot-water storage tank is heated. The set- tings are different, depending on the type of hot-water circuit installed. The following pages describe the charging temperature settings for three different charging procedures a — Page 60 Service Settings Charging procedure b Charging procedure b is used in application 3, 4, 11 and The hot-water circuit has indirect storage tank con- trol, and the tank is equipped with an internal heat ex- changer.
The following settings are available: Display text Parameter Default value, Page 61 Service Settings Charg. Charging procedure c This charging proecedure is used in application 5, 6, 7, 8 and The hot-water service system has indirect storage tank charging and the tank has no internal heat exchanger.
For this type of system, the following settings are avail- able: Display text Parameter Pump This group of settings determines how pumps in the system operate.

Page Common Functions Service Settings For example, you can select which language should be used in the display, you can set the time and date and you can change the access code. The most important of these are explained on the following pages. Page Alarm Status Service Settings Alarms can be generated based on measurement data from all relevant sensors, i. There is an Alarm Status picture for every sensor that has an alarm setup, as explained on page All settings can still be seen.
A listener is a slave controller with address 0 in a master - slave system. A listener receives T. In total When the listener only needs to receive the T. When the listener needs to receive the T. These buses are totally different. When the application has been uploaded in the ECL controller, the ECA 30 will be updated and having a much quicker reaction.
One ECA Demands: - The master must send T. The outdoor temperature sensor must be connected to the base part of the master controller. Procedure: 1. Don't place any ECL controllers in any base part. Insert in its base part the ECL controller which must be addressed with the lowest slave number, for example "1".
Power up the units. The ECL address has now been set to See extra info "Reset ECL address" at the end of this document. This will ensure that the ECA has address A and it is connected to address 15 which is required in order to install an application in the ECL controller. Insert the appl. Choose language. Choose application not possible for A because only one subtype exists.
Set Time and date 9. Choose "Next" Display shows shortly "Application A The display shows an application related menu. Giving the slave an address number a. Select an ECL menu b. Choose MENU c. Choose "Common controller settings" d. Choose "System" e. Choose "Communication" f. Choose "ECL addr. Select "ECL addr. Change the address to the planned address number for this slave i. After 5 sec, the chosen address number changes to a "0" j. A master is not present on the ECL bus.
Setting the ECA to communicate on address 15 a. Choose "ECA system" c. Choose "ECA communication" d. Choose "Connection addr. Follow points Follow points 6 - The Master controller has address 15 from the factory, so it does not need to be addressed. The entire communication set-up is finished. This will take approximately 15 seconds.
As all ECL controllers on the ECL network will get their ECL address changed to 15 it is recommended that all other controllers except for the intended master controller are turned off or removed from its base part before this function is activated. The whole operation will take approximately 25 seconds. If multiple controllers end up with address 15 then there is a risk that they will conflict with each other.
It is therefore necessary to manually check and reset the ECL addresses of slave controllers after this function has been used. Main items in A The pulses from the flow meter are applied to the ECA 32 module's pulse input. A was originally made with A As per January the A appl. Main differences, compared to A Sensor S4 is DHW-heating temp. Unfortunately, we have seen some ECL base parts where the right terminal block's position has changed in up-down direction. This means that temperature sensors are not seen correctly from the ECL Correct position is with two terminals space above and below the terminal block.
As from start of year , the production line has tested correct terminal block position. The combination balances the system hydronically, allow remote access via a BMS and provides actual energy consumption data per climate panel during both heating and cooling operation. In Europe, 30 percent of all energy consumption goes to heat or cool buildings. Danfoss has the solution to lower energy usage and improve indoor climate by adding a digital element: Leanheat software.
