ERGO GALLETTI MANAGEMENT SOFTWARE
If you are using ERGO Galletti management software it is also
possible to connect a Chiller/Heat pump to the supervision
system. In this way, the management software analyses the
system's data and adapts operation to the real needs.
ERGO management software can assign 4 different degrees
of freedom to the LCD controller, based on the type of
remote control that has been assigned through the software.
LOCAL: all of the functions are accessible on the
controller: speed choice, temperature, cooling or
heating mode, ON/OFF. All of the operation parameters
are read by the system.
REMOTE CONTROL A - cooling or heating mode is set
from the ERGO software; all of the other functions are
accessible on the controller: speed choice, temperature,
ON/OFF. All of the operation parameters are read by the
system.
REMOTE CONTROL B - The user can choose the
based on the value set through ERGO. The operating
mode is set by the software.
REMOTE CONTROL C - No function can be set on the
control panel, it is fully managed by the software.
"SMALL" NETWORK SOLUTIONS
"SMALL" network solutions constitute a MASTER/SLAVE
network system where one of the EVO controllers performs
the function of MASTER while all of the other EVO controllers
on the network perform the SLAVE function.
It can be set up in two different ways, each with different
functions and type of connection:
SMALL network on RS485
SMALL network on CONVEYED WAVES
SMALL NETWORK ON RS485
In this case the connection is set up using bus RS485,
comprised of a twisted 2-conductor, shielded data cable
(figure 02).
For details on how to wire the network, read
"RS485 NETWORK GUIDE LINES" available in
the download area of the Galletti website.

USER MANUAL
IT IS strictly forbidden to reproduce this manual, even partially
The MASTER controller sends the following settings to the
SLAVE controller:
Operating mode: (COOLING or HEATING);
ON/OFF status of the controller: all of the SLAVE
controllers switch to the ON/OFF status of the MASTER
controller;
Enabling minimum room temperature control;
Room temperature SET;
or (based on the "Temperature control from MASTER"
parameter in the "Networks and Connections" menu):
Limits that apply to changes in the room temperature
SET (both SUMMER and WINTER): on each SLAVE
controller, the SET variation is allowed with a delta of ±
2°C around the value of the SET entered on the MASTER
controller.
In terms of the ON/OFF status, the following is allowed on
each SLAVE controller:
Automatic local ON when requested by the minimum
room air temperature control function.
Automatic local ON/OFF depending on the time slots,
if enabled;
OFF on SLAVE controller from digital input if it is
enabled.
Each SLAVE controller maintains its autonomy in managing
ventilation speed, in switching the ECONOMY function
on and in setting the SET value (with the limits described
above).
This type of network does not allow a supervision network
to be included (ERGO solution) as the RS485 serial ports on
all of the controllers (both MASTER and SLAVE) are already
occupied by the SMALL network arrangement.
Once the network has been wired, it is necessary to configure
each EVO controller. Press PRG to access the MENU and then
enter sub-menu "Networks and connections" (password =
20). Set the SETUP RS485 parameters as follows:
MST/SLV = set "Master" on the EVO controller acting
as the MASTER on the network, and set "Local Slave"
on all of the EVO controllers acting as the SLAVEs in
the network.
Protocol = "Modbus"
Serial address = set a value between 1 and 255, only
in the SLAVE controllers.
