Connection Server Installation Manual

3.2.3. Connection of air conditioning units

Connection of air conditioning units

There are two ways of connecting air conditioning units in iMM system:

a) Direct

b) Indirect

a) Direct connection means that the air conditioning unit control protocol is implemented directly in

iMM. Currently air conditioning units of LG brand are supported; others have been worked on. We

support communication of LG air conditioning units which is marked as PI485. Any LG unit supports

that interface; it can be interconnected to application iTP via iMM.

b) Indirect connection means utilization of communication unit CoolMaster which can communicate

with different types and makers of air conditioning units (http://www.inels.cz/media/PDF-

export/download/Coolmaster_compatibility.pdf). CoolMaster is then controlled from iMM.

Interconnection is performed by means of 485/ETHERNET converter. Steps for communication

setting:

1. Connect the converter to communication interface of air conditioning unit and to ethernet.
