Function overview

With the available as an accessory EWPM extension it is possible to integrate a Dimplex heat pump with a heat pump manager into a KNX bus system. Values for up to 110 group addresses can be sent from the heat pump manager to the KNX bus system or sent from the KNX bus system to the heat pump manager. Among other things, it is possible to read out the status, the operating data or the history in order to visualize this later on the KNX level. The operating mode, the target hot water temperature or the heating curve could also be changed.

New:
Should the function of the intelligent room temperature control Smart-RTC + be used despite the existing KNX room sensors? From the heat pump manager software WPM_L23.1, it is possible to send the room temperature, room humidity and target room temperature of up to 10 rooms with KNX room sensors from the KNX bus to the heat pump manager. Further information and descriptions are given in the chapter Room temperature control Smart-RTC + made available.

System requirement

The minimum system requirement for using the EWPM extension is a Dimplex heat pump with heat pump manager WPM 2006, WPM 2007 or WPM EconPlus from software version H_H50 and higher. For the programming a PC with ETS3, ETS4 or ETS5 software (not included), a Project file, the "KSet" programming tool and a Data point list needed.

installation

ATTENTION
Before opening the device, all circuits must be disconnected from the power supply. All electrical connection work may only be carried out by a qualified electrician or a specialist for specified activities in compliance with the installation and operating instructions.

The installation of the EWPM extension takes place on the heat pump manager in the designated slot “Serial Card / BMS Card”. The following steps are carried out:

  • De-energize the heat pump manager

  • Remove the cover of the “Serial Card / BMS Card” slot with a small screwdriver

  • Remove the cover of the “Serial Card / BMS Card” slot with a small screwdriver

  • Installation of the EWPM extension

  • Breaking out the existing cover

  • Close the opening with the cover

 

 

  • Supply the heat pump manager with voltage

Electrical connection

The EWPM extension is connected to the KNX bus using the enclosed terminal. The device is supplied with power via the KNX bus. It should be noted that a new EWPM extension does not have a physical address owns and before programmed must become.

Heat pump manager settings

Depending on the software version of the heat pump manager, the following settings must be checked and, if necessary, adjusted:

Import device into ETS

The EWPM extension is integrated into the ETS by importing a Project file. In the Project file the device "EWPM Plugin" is included. After the successful import, the physical address programmed and the project-related XML file Loading.

NOTE
Before a bus monitor or communication with another application can be started, communication with the device must first be established! If this is not the case, the error message appears: "Verify connection cable and restart procedure"

Bus communication error

Physical address

In order to program the physical address via the ETS, the programming button on the EWPM extension must be pressed. Then the green LED starts to light up. This goes out when the device has successfully received the physical address from the ETS.

Program communication EWPM <-> KNX bus

An XML file is required for communication between the KNX bus and the heat pump manager. This XML file must be created and adapted according to the relevant system parameters and customer requirements. The program KSet needed.

Programming tool KSet

After installing and opening KSet it is recommended to use the attached file Example.xml to open. In Example.xml the most common standard addresses are preset at the factory.

First of all, the system-specific addresses to be transmitted should be specified. The main / middle and subgroups are then created in the ETS for the addresses. Means KSet the XML file is now edited. The following figure shows the structure of the XML file in KSet shown. The individual columns are described in the following table.

Data point list

The data point lists listed in the following tables contain the most frequently used addresses. The tables are subdivided according to the menus contained in the heat pump manager. The following examples deal with addresses that have some special features and must be explained separately.

Data points that can be written via the KNX bus are marked with "IN", those that deliver values to the KNX bus are marked with "OUT".

NOTE
With the current firmware of the EWPM extension, no values can be read via the KNX bus. The values are sent to the KNX bus cyclically or when the value changes!

*NOTE
A quantity of heat can only be output for heat pumps with pressure sensors or an external heat meter WMZ!

Example of heat quantities*

The heat quantities are made up of 3 addresses. These 3 addresses must be combined with the following formula for the amount of heat.

Heat quantity heating = (14/3/225 * 100000000) + (14/3/224 * 10000) + 14/3/223

2nd / 3rd heating circuit

In order to be able to make changes to the 2nd or 3rd heating circuit, the changeover must take place via an address. After switching over this address, it is possible to change parameters in the desired heating circuit without any problems.

* ProgrammingNOTE
When selecting the 2nd heating circuit, the value 2 is initially sent to address 209 or 289. The required values for the 2nd heating circuit can then be changed. Analogous to the description, this is done with the 3rd heating circuit and the value 3.

Selection of time functions

Access to the time functions, e.g. for blocking, lowering / increasing values or times, is achieved by switching over the address 192 (Modbus IP 5065).

* ProgrammingNOTE
To change a reduction or increase value for the 1st heating circuit, the value 1 for reduction or 2 for increase is sent to address 192 (Modbus IP 5065). The required values for the 1st heating circuit can then be changed. Analogous to the description, this is done with the 2nd and 3rd heating circuit or blocks for e.g. hot water and swimming pool preparation.

NOTE
In the event of a change, the status of the output is sent by the heat pump manager via the data points outputs. It is not possible to write to this data point!

Time alignment

Using the time synchronization, it is possible to write the current date and time via the interface. So that the change is accepted by the heat pump manager, the value 1 must be written to the associated "set register" immediately after the time has been written. Only then will the change be applied. The value of the "set register" is automatically reset to the value 0 after writing.

Function descriptions

In this chapter, some functional descriptions, their implementation and recommendations are collected and explained.

Room temperature control Smart-RTC +

From software version WPM_L23.1 it is possible to use the function of the intelligent room temperature control Smart-RTC + via the BMS interface with the KNX protocol available on the heat pump manager.

The values of the room temperature, the room humidity (for cooling) and the target room temperature of a maximum of 10 rooms must be sent to the heat pump manager via the KNX bus. The heat pump manager uses these values to calculate the maximum system temperature required for heating and the minimum possible system temperature for silent cooling, taking the dew point into account. At the end of this functional description there is a Example project for the ETS4 / 5 made available. This project folder also contains the XML file related to this project.

Necessary settings on the heat pump manager

To use the BMS interface for the intelligent room temperature control Smart-RTC +, additional settings must be made or adjusted on the heat pump manager.

IMPORTANT
The number of room controllers must be adapted to the number of KNX room sensors that should also send values to the heat pump manager. The heat pump manager can process values from a maximum of 10 room controllers.

Room control data points

Since only a limited number of addresses are available, the time function switch from Chapter is required to write the values for the rooms
