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:

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.

Software version	Pre-configuration menu	Submenu	Setting value

Software version	Pre-configuration menu	Submenu	Setting value

		1. Heating / cooling circuit heating room control	BMS
		1. Heating / cooling circuit cooling room control	BMS
		1. Heating / cooling circuit Number of room controls	01-10

When using an additional 2nd heating or heating / cooling circuit, the settings must be made in the same way as for the 1st heating circuit.

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 "Selection of time functions" utilized. The addresses 50 - 59 for the 1st heating / cooling circuit and 60 - 69 for the 2nd heating / cooling circuit are available for access. A switchover takes place via address 272.

Example for writing the room values

The following table relates to the group addresses in the sample project.

Surname	e.g. Group Address

Surname	e.g. Group Address
Read number of rooms	14/5/1 (sensor)
Switch room address 50 - 59	14/5/2 (actuator)
Write actual room temperature RIT addr. 50 - 59	14/5/4 (actuator)
Write actual room humidity RIF addr. 50 - 59	14/5/6 (actuator)
Write room target temperature RST addr. 50 - 59	14/5/8 (actuator)
Write room release RFG addr. 50 - 59	14/5/10 (actuator)

The address (14/5/2) is switched over to transfer the room values. The following description is intended to represent one possibility of such an implementation. The room values are written to the heat pump manager every 1 minute per room. With 10 rooms, this means a maximum processing time of 10 minutes. This lead time is not a problem with the small changes in room values and will not limit comfort.

Module 1 - Switching the room addresses

In module 1, a counter is first created which counts up by +1 every minute (pulse for minute). The count starts at 50 and ends with the number of room controllers set (sensor 14/5/1). After the number of set room controllers has been reached, counting starts again at address 50. This count value is written to actuator 14/5/2 every minute. At the same time, marker 1 (AI memory flags 1) is also filled with the counter value. Flag 3 (AI memory flags 3) triggered with the minute pulse. Both flags are required in module 2. The input M with the constant 0 means that the counter starts again at 50 when the number of set room controllers is reached and does not stop when the set room controllers are reached.

Module 2 - Delayed writing of the room values

After switching the room addresses with module 1, the writing of the values via actuators 14/5/4 (room temperature), 14/5/6 (room humidity), 14/5/8 (target room temperature) and 14 / is delayed by 3 seconds. 5/10 (room clearance). For this, marker 1 (AI memory flags 1) and marker 3 (AI memory flags 3) from step 1 are required. First, a delayed pulse by 3 seconds (delayed time 3 sec.) Is filled via marker 3 (AI memory flags 3). The delayed pulse triggers the analogue memory, which is already filled with marker 1 (AI memory flags 1) count value from module 1. If the delayed pulse is triggered, the value is written from the analogue memory to marker 2 (AI memory flags 2). The value in marker 2 (AI memory flags 2) is still required in module 3.

Module 3 - Compare the room address to be written

The marker 2 (AI memory flags 2) from module 2 contains the current value of the room address that is to be written. So that the correct trigger of the room address is triggered, the room address from marker 2 (AI memory flags 2) must be compared. The marker 2 (AI memory flags 2) is compared with the constant 50 (Constant 50). If the value is the same, another marker 50 (AI memory flags 50) is set. The marker 50 (AI memory flags 50) is required in module 4 and triggers the trigger there.

Module 4 - Writing the room values to the buffer

Module 4 is explained using the example of the target room temperature for room address 50 (Room-set-temperature 50). First, the target room temperature (Room-set-temperature 50) is multiplied by the factor x10. This is necessary because only integers (*) are written. The result is written to an analogue memory. If the marker 50 (AI memory flags 50) is triggered from step 3, the number in the analog memory (analogue memory) is written to the marker RST 50 (AI memory flags RST 50), which in turn simultaneously drives the actuator 14/5 / 8 triggers for the target room temperature.

Module 5 - Writing the room values to the heat pump manager

Module 5 shows how the room values are triggered in the actuator. It stands
RIT => actual room temperature
RIF => actual room humidity
RST => target room temperature
RFG => room release.

summary

The modules 1 - 5 serve as an example and represent a possibility for the implementation of the description of the room values. The process was deliberately divided into individual modules so that the process can be explained as simply as possible. The modules shown can also be combined, structured differently, or other paths can be selected.

Smart-Grid / SG Ready

The use of photovoltaic electricity ultimately represents a load-variable tariff, since the heat pump can be operated with inexpensive electricity with photovoltaic yield. In this case, a digital input for "green" electricity can be connected on the heat pump manager. In this operating state, the heat pump runs in increased mode for room heating (return target temperature + increase value) and hot water preparation (maximum temperature hot water). The possibility of release via the available interfaces is also given from heat pump manager software version L20.2. The wiring of the digital input is then not required to enable the function.
