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.

1.1 Functionality

IntesisTM continuously monitors Hisense VRF network for all configured signals and keeps the updated status of all of them in its memory. It triggers updates on configured group addresses to KNX network on value change.

Commands toward the indoor unit communication adaptor are permitted. Each indoor unit is offered as a set of KNX objects.

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.

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

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

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

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.

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

Connect a USB storage device (not a HDD) if required. Check the user manual for more information.

Ensure proper space for all connectors when mounted (see section 6)
