The Giacoklima bus system equipped with the KM203 network controller allows for remote control and supervision, via Serial communication, of the whole heating/cooling framework.

Communication

Connect HSYCO to the KM203 controller employing an RS485 gateway.

RS-232 parameters:

Baud rate 19200
Data bits 8
Stop bit 1
Parity none
Flow control none

The Giacoklima bus architecture

This image illustrates an example of the system architecture: The RS485 port is on the top left corner of the KM203 interface as shown in the picture above.

HSYCO Configuration

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 1 n > 0 the data acquisition interval, in seconds

The Giacoklima bus architecture

The gkbus.ini file is a specific configuration file located in the main directory (same directory as hsyco.ini or hsyco.jar).

Here you must add a line for each thermostat belonging to the framework and optionally specify a descriptive name of the corresponding area.

Use the format “<ioserver_id>.k<n>.<addr> = name”, where <ioserver_id> is the id of the referred I/O server, <n> is the number of the KPM20 module the thermostat is connected to and <addr> is the secondary address of the thermostat.

For instance:

gk.k0.0 = Kitchen
gk.k0.1 = Bedroom
gk.k1.0 = Entrance

Datapoints

ID Value R/W Description


User Interface

You can use a [tempmini] object to create a thermostat-equivalent interface. Set the Server ID field to the I/O Server’s name and specify the address of the thermostat (K483 module) in the Address field using the format “k<n>.<addr>” where <n> is the number of the KPM20 module the thermostat is connected to and <addr> is its address (e.g. k0.1 represents the second thermostat connected to the first KPM20).


UISET Actions

You can use any object that accepts a text attribute, usually text, but also marquee and others, to display the status of the system according to the following table:

USER Commands

The CSx75 I/O Server supports a few system commands to be inserted within the Web interface. The controls are directly supported as ordinary user objects, by setting the name and param fields according to the following table:
