Open Web Net My Home – Daikin Interface

www.myopen-legrandgroup.com

What we are going to do

We are going to build a basic system using several My Home devices to connect and

control a CoolMaster Daikin interface unit. The CoolMaster is a really useful interface that

can control to a Daikin HVAC system using a RS232 protocol.

Steeps

1. – Building the setup

2. - Configuration all the devices in the set up

3. – Run some tests

WHAT YOU WILL NEED

1. – Any My Home Gateway like MH200N or F454 this tutorial uses the MH200N

2. – Any Power Source like E49 for SCS Bus, or 346020 for MH200N this tutorial use the

346020

3. - Bticino TouchScreen H4890

4. - IRSplit Interface 3456 one for each internal unit we are controlling, in this case we are

using 3 off them.

5. - CoolMaster 1000D Daikin VRV Supply by Cool Automation

6. - DS1206 supply by Tibbo Technology, this device need also a power source supplied

by third party

7. - USB to RS232 converter, you need this only in case your PC don’t have one of them,

this device is used to simulate some internal units in the CoolMaster if you have the actual

units connected to the CoolMaster you probably won’t need this device.

8. - Several hardware, Serial cable, Network cable, power supply etc.

Abstract

Basically we need to translate Open Web Net messages into RS232 messages for

CoolMaster in a reliable way to control the Daikin system. As you know Open Web Net is

based on IP protocol, so we need to translate from IP to RS232.
