EVO

GENERAL FEATURES

The EVO controller is designed to control all of the system
units in the Galletti range with multi-speed, single-phase
motor or coupled to an inverter for speed modulation.
The EVO controller system is composed of:
I/O board containing the power supply circuit,
the microprocessor system and the connectors
(unscrewable) to connect the input and output devices;
User unit composed of graphic display and keyboard
(six keys) equipped with clock and probe to read the
room temperature.
The connection between the I/O board and the
user unit is set up using the relative connectors
and a data transmission cable fitted with a pair
of twisted conductors and shielding.
The controller makes serial communication possible on two
types of networks:
ERGO solution: connection to an external supervision
system with MODBUS RTU protocol on serial RS485
(the Galletti ERGO system, for example);
SMALL solution: connection of multiple EVO controllers
in two possible configurations:
- MASTER/SLAVE on serial RS485
- MASTER/SLAVE on CW (Conveyed Waves), which
can also be set up with ERGO solutions.

MAIN FUNCTIONS

Automatic or manual fan speed variation (selected
from the keyboard);
Management of ON/OFF or modulating valves for two
or four-piped systems.
SUPPORTING electric heater control, used during
heating;
SUMMER/WINTER mode switch (= cooling/heating)
in four possible ways:
- manually, from the keyboard;

dehumidification function control;
operation with TIME SLOTS.
It is also supplied with:
External pre-consensus digital input (for example:
window contact, remote ON/OFF, presence sensor, etc.)
that can enable or disable unit operation (contact logic:
see board configuration parameters);
Digital switching input Remote centralised Cooling/
Heating (contact logic: see board configuration
parameters);
Digital input to enable ECONOMY function from
remote control (contact logic: see board configuration
parameters);
Water temperature probe (accessory), one or two
(optional with 4-pipe systems);
STANDARD room air temperature probe (installed
inside the user unit);
Remote room air probe (accessory) that can be used,
if connected, in place of the standard one installed in
the user interface;
Remote relative room air humidity probe (accessory);
A completely configurable digital output (dry contact).
