1 Description

Introduction

This document describes the integration of Hisense VRF air conditioning systems into KNX home automation systems using gateway Intesis KNX – Hisense VRF.

The aim of this integration is to monitor and control your Hisense air conditioning system, from your KNX TP-1 installation. To do it so, Intesis performs as a one more KNX device, sending and receiving telegrams to group addresses in the KNX network.

Intesis makes available the Hisense air conditioning system indoor units’ datapoints through independent KNX objects. Up to 64 indoor units supported, depending on product version. This document assumes that the user is familiar with KNX and Hisense technologies and their technical terms.

2 KNX System

In this section, a common description for all Intesis KNX series gateways is given, from the point of view of KNX system which is called from now on internal system. Connection with the Hisense system is also called from now on external system.

Description

Intesis KNX connects directly to the KNX TP-1 bus and performs as one more device into the KNX system, with the same configuration and operational characteristics as other KNX devices.

Internally, the circuit part connected to the KNX bus is opto-isolated from the rest of the electronics. Intesis KNX receives, manages and sends all the telegrams related to its configuration to the KNX bus. On receiving WRITE telegrams of KNX group addresses associated to communication objects, the corresponding

messages are sent to the external system (Hisense installation). When a change in a signal of the external system is detected, a WRITE telegram is sent to the KNX bus (addressed

with the group address associated to the corresponding group object), in order to maintain both systems synchronised in every moment.

The status of the KNX bus is checked continuously and, if a bus drop-down is detected, for example due to failure in the bus power supply, after the KNX bus is restored again, Intesis will send READ telegrams to group addresses of all communication objects marked with flag ‘Ri’. The behaviour of each individual point into Intesis is determined by the flags configured for the communication object. See details below.

Points definition

Every group object in configuration has following KNX properties:

Property

Description

Descriptive information about the communication object or signal.

Object function

Information on range of values for the group object.

DPT

Datapoint type. It is the KNX data type used to encode the signal's value. It will depend on the type of signal associated in the external system in every case.

Group

It is the KNX group to which the point is associated. It is also the group to which the read (R), write (W), transmit (T), update (U) and read on init (Ri) flags are applied. It is the sending group.

Listening addresses

They are the addresses that can write on the group object, a part of the main group address.

R

Read. If this flag is activated, READ telegrams of this group address will be accepted.

Ri

Read on Init. If this flag is activated, the object will trigger corresponding READ request (on associated group address) on initialization.

W

Write. If this flag is activated, WRITE telegrams on this group object will be accepted.

T

Transmit. If this flag is activated, when the group object value changes, due to a change in the external system, a WRITE telegram of the associated group address will be sent to the KNX bus.

U

Update. If this flag is activated, UPDATE telegrams (response to READ telegrams) on this group object will be accepted.

Active

If activated, the point will be active in Intesis, if not, the behaviour will be as if the point is not defined. This allows deactivating points without the need of delete them for possible future use.

These properties are common for all Intesis KNX series gateways. Although each integration may have specific properties according to the type of signals of the external system.

See list of communication objects in section 9 APPENDIX A – COMMUNICATION OBJECTS TABLE.

3 Connections

Find below information regarding the Intesis connections available.

Power Supply

Must use NEC Class 2 or Limited Power Source (LPS) and SELV rated power supply.

If using DC power supply:

Respect polarity applied of terminals (+) and (-). Be sure the voltage applied is within the range admitted (check table below). The power supply can be connected to earth but only through the negative terminal, never through the positive terminal.

If using AC power supply:

Make sure the voltage applied is of the value admitted (24 Vac). Do not connect any of the terminals of the AC power supply to earth, and make sure the same power supply is not supplying any other device.

Ethernet

Connect the cable coming from the IP network to the connector ETH of the gateway. Use an Ethernet CAT5 cable. If communicating through the LAN of the building, contact the network administrator and make sure traffic on the port used is allowed through all the LAN path (check the gateway user manual for more information). Default IP is

192.168.100.246. DHCP is enabled by default.

PortA / KNX

Connect the KNX TP1 bus to connectors A3 (+) and A4 (-) of gateway’s PortA. Respect the polarity.

PortB / H-Link Hisense

Connect the H-Link terminals (TB2) of Hisense Outdoor Unit to the connectors B1 and B2 of gateway’s PortB. There is no polarity to be respected.

Console Port Connect a mini-type B USB cable from your computer to the gateway to allow communication between the Configuration Software and the gateway. Remember that Ethernet connection is also allowed. Check the user manual for more information.

USB

Power device

The first step to perform is to power up the device. To do so, a power supply working with any of the voltage range allowed is needed (check section 5). Once connected the ON led will turn on.

WARNING! In order to avoid earth loops that can damage the gateway, and/or any other equipment connected to it, we strongly recommend:

• The use of DC power supplies, floating or with the negative terminal connected to earth. Never use a DC power supply with the positive terminal connected to earth.

• The use of AC power supplies only if they are floating and not powering any other device.

Connect to Hisense installation

Use the Port B connector of the Intesis device in order to connect Hisense H-Link bus to the Intesis. Remember to follow all safety precautions indicated by Hisense.

Connect the Hisense H-Link bus to connectors B1 and B2 of gateway’s PortB. Bus is not sensitive to polarity.

Connection to KNX

Connect the KNX TP1 bus to connectors A3 (+) and A4 (-) of gateway’s PortA. Respect the polarity.

Connection to the configuration tool

This action allows the user to have access to configuration and monitoring of the device (more information can be found in the configuration tool User Manual). Two methods to connect to the PC can be used:

• Ethernet: Using the Ethernet port of Intesis.

1. Device configuration

1.1. Physical Address. KNX physical address of the device in the network

1.2. Extended Addresses. Enables usage of KNX Extended addresses (rangefrom 16/0/0 to 32/7/255).

2. Operating Mode. Settings related to KNX interface for control and feedback of AC unit’s operating mode.

2.1. KNX DPT for HVAC operation mode comm object. Base DPT. Base DPT to use for control/monitor the

operating mode. Following DPT types are offered:

o DPT_20.105. DPT_HVACContrMode: 0-Auto, 1-Heat, 3-Cool, 9-Fan, 14-Dry o DPT_5.x (non-standarized): 0-Auto, 1-Heat, 2-Dry, 3-Fan, 4-Cool

2.2. KNX DPT for HVAC operation mode comm object. Extra DPT. Additional DPT to use for control/monitor

the operating mode.

o DPT_1.100. DPT_Heat/Cool: 0-Cool, 1-Heat. o DPT_5.001. DPT_Scaling: Enables objects “Control_ Heat Mode & On” and “Control_ Cool Mode &

On”. Their type is DPT_Scaling (0..100%), and their ending is to be able to control parameters On/Off, Cool/Heat of indoor unit from a single percentage object. They are meant to provide compatibility with certain thermostats oriented to the operation of valves for Heating/Cooling. Whenever a value > 0% is received at each of these two objects, the corresponding operating mode and ON operation is sent to the indoor unit. Whenever both values are 0%, indoor unit is set to OFF

2.3. Use of 1-bit Operating Modes. 1-bit Control Objects. Enables a bit-type object for the control of each

operating mode.

2.4. Use of 1-bit Operating Modes. 1-bit Status Objects. Enables a bit-type object for monitoring each

operating mode.

3. Temperature Sensor.

3.1. Ambient temperature provided from KNX. Enables object Control_ KNX ambient temperature.

NOTE: Indoor unit does not accept, by itself, that an ambient temperature for control of operation

of the indoor unit is provided. To allow regulation of indoor unit according to a temperature reference from KNX, what Intesis does is passing a different temperature setpoint to the indoor unit than the

one required by the user. The passed setpoint is such that the difference ‘Ambient temperature

reported by Hisense IU – AC setpoint’ is equal to ‘Ambient temperature reported by KNX – AC

setpoint required by KNX’, using the following formula: “AC Setp. Temp” = “AC Ret. Temp” - (“KNX Amb. Temp.” - “KNX Setp. Temp”)

Where:

▪ AC Setp. Temp: AC indoor unit setpoint temperature

▪ AC Ret. Temp: AC indoor unit return temperature ▪ KNX Amb. Temp.: Ambient temperature provided from KNX ▪ KNX Setp. Temp: Setpoint temperature provided from KNX

Consequently, when using this feature (Ambient temp provided from KNX), setpoint at AC and setpoint in KNX will not necessarily be the same (actually, user will not be able to operate setpoint

from AC System controllers as the remote controller).

2. Install Intesis in the desired installation site. Installation can be on DIN rail or on a stable not vibrating surface (DIN rail mounted inside a metallic industrial cabinet connected to ground is recommended).

3. Connect the KNX communication cable coming from the KNX network to the port marked as Port A on Intesis (More details in section 3).

4. Connect the communication cable coming from the Hisense H-Link installation to the port marked as Port B of Intesis (More details in section 3).

5. Power up Intesis. The supply voltage can be 9 to 36 Vdc or just 24 Vac. Take care of the polarity of the supply voltage applied.

WARNING! In order to avoid earth loops that can damage Intesis and/or any other equipment connected to it, we strongly recommend:

• The use of DC power supplies, floating or with the negative terminal connected to earth. Never use a DC power supply with the positive terminal connected to earth.

• The use of AC power supplies only if they are floating and not powering any other device.

6. If you want to connect using IP, connect the Ethernet cable from the laptop PC to the port marked as Ethernet of Intesis (More details in section 3).

If you want to connect using USB, connect the USB cable from the laptop PC to the port marked as Console of Intesis (More details in section 3).

7. Open Intesis MAPS, create a new project selecting a copy of the one named INKNXHIS---O000.

8. Modify the configuration as desired, save it and download the configuration file to Intesis as explained in the Intesis MAPS user manual.

9. Visit the Diagnostic section and check that there is communication activity, some TX frames and some other RX frames. This means that the communication with the KNX installation and Hisense installation is OK. In case there is no communication activity between Intesis and the KNX side and/or Hisense units, check that those are operative: check communication cable used to connect all devices and any other communication parameter.
