C-Bus to Daiken Interface

Well, maybe I was too agresive. As a matter of fact when this tread started, I wanted to remind you about the coolmaster
http://www.cbusforums.com/forums/showthread.php?t=4007&highlight=coolmaster

However, I couldn't access their site from my jobs network - I still can't.

However I have to admit that when I emailed to them (it was Sunday afternoon) they call back after 15 minutes.

 

What! 15 min, that's way too long...

 

As I understand, DBACS solution is ready to use with usual PC interface, and Coolmaster solution needs PAC and self-made rs232 logic programming?

 

Coolmaster cost??

This product looks good did anyone have the rough cost for this unt???

 

Not cheap... about $2k aussie!

 

Yes nickrusanov you are absolutely right. coolmaster has to connect to a serial port and you have to do your own logic.

I just completed a project. When the project first started we had to exclude ac simply because of the complexity of ac integration. However after seeing all the posts here I decided to do some research.

Coolmaster is a great solution, but you need to have access to a serial port and have to parse RS232 messages on your own and somehow display that information on cbus gear.

This is one of the reasons why I decided to go with the other solution. But the deciding factor was the Daikin warranty issue. I read this thread and other similar ones on the web. Coolmaster connects directly to ac system (something they call f1 f2 terminal). I have found that this voids the Daikin Warranty.

I found the documentation of the DBACS Solution pretty descriptive. But I found the following to be confusing.

1) Temperature up/down controlling. Manual says send a group address on command. But when you program buttons you need to make the button type a bell press. If not it won?t send on commands, if the group address is already on.

2) They change a group address level to change the ac function (cool, heat etc). But you need to be make sure what states in the manual is the actual level. Not a percentage. Cool is level 1 and this is not 1%. Heat is level 2 etc. etc.

Anyway everything worked out smoothly. send me a message if you need to have a look at my piced file.

 

why dont you send me the document.infact am also looking for the same

why dont you sendme that document.am also looking for the same.

 

Plz send me that documetn

Dear nikrusanov,

Can u sen me that document plz.
