Mitsubishi

The MITSUBISHI air-conditioning system equipped with one of the centralized controllers among G-50, GB-50, or AG-150 allows for remote control and supervision, via Ethernet communication, of the whole framework.

This I/O Server complies with the XML API for the Mitsubishi M-NET proprietary protocol.

In order to connect the Mitsubishi controller with HSYCO, the Web Monitor and Annual Schedule pin codes activation are required. On request, Mitsubishi will provide a document to be compiled for the activation.

Communication

The Mitsubishi controller replies on the port 80 (10 sockets) or 1025 (4 sockets) of its IP address.

M-NET Configuration

All the devices comprising the M-NET architecture are assigned an address ranging from 0 to 250.

Conditioners and lossnay modules can be associated to 50 different groups (indexed from 1 to 50). The control of these modules is thus performed addressing the group they belong to.

Further, it is possible to expand the system using up to three ECs which allow to replicate a full M-NET architecture under each EC. In this case, modules are addressed specifying both the EC and the group they belong to.

HSYCO Configuration

Add a MNET I/O Server in the I/O Servers section of the Settings and set its parameters:

Communication

• IP Address: IP address of the controller
• IP Port: TCP/IP port to use, can be set to 80 or 1025, leave blank to use default port 80.

High Availability

• Shutdown when inactive: defaults to true.

Options

ID	Default	Values	Description
gui	true	true	enable support for the UI object, UISET actions and USER commands
		false	disable UI support
startupevents	false	true	generate IO events also during the driver’s start-up phase
		false	start generating events only after HSYCO is aligned with the current status of the system
pollinterval	20	n > 0	the data acquisition interval, in seconds
ec	0	0 - 3	specifies the number of ECs connected to the main controller. A value of 0 indicates that no EC is used

Datapoints

In the following tables, replace <target> with "system" for sending the command to all the defined groups. If ECs are used (i.e. the option “ec” is set to a value greater than 0), you can specify “ec<s>” (with <s> ranging from 1 to the specified value of ECs) as target to address a single sub-system.

Further, replace <n> in “g<n>” with a group number ranging from 1 to 50 and replace <m> in "a<m>" with an address from 0 to 250.

If ECs are used, it is necessary to specify the EC number we are addressing too. To this end, prepend the string “ec<s>.” to the group or the address.

For instance, when an EC is used, the following datapoint ID is not correct:

g1.power

The correct one to be used is the following:

ec1.g1.power

Note 1 

For some modes the temperature must be set following these ranges:

• modes “cool” or “dry”: 19 - 30
• mode “heat”: 17 - 28
• mode “auto”: 19 - 28

If <target> is set to “system” or “ec<s>” and the specified temperature parameter doesn’t respect the above mentioned ranges for a group belonging to the target, then the temperature is not changed for that group and an error message is logged.
