Modulating devices control
EVO is capable of simultaneously controlling up to two modulating valves
and one BLDC fan, making it possible to vary the air flow rate and the water
flow rate in the heat exchanger, adapting to the thermal load.
Humidity control
EVO offers the possibility of automatically activating a dehumidification
process depending on the relative humidity and a settable setpoint. This
function requires a humidity sensor that is available as an accessory.
Serial Communication
The controller has serial ports for RS485 communication and power-line
communication that allow the development of control networks that are
adequate for every need.
ZA - Pair of support covering feet for GTFA
models
The ZA covering feet, designed for the
installation on éstro GTFA models are supplied
in pairs and comprise supports for fastening to
the base unit and outer coverings for fastening
to the cabinet. They are used to conceal the
plumbing (pipes leading up from the floor) and
in cases where the fan coil unit cannot be anchored to the wall. The height
of covering feet is 100 mm.
ZAG - Pair of support covering feet with front
grille for FA models
The ZAG covering feet, designed for the
installation on éstro GTFA models are supplied
in pairs and comprise supports for fastening to
the base unit, outer coverings for fastening to
the cabinet and the front covering grille. They
are used to conceal the plumbing (pipes leading
up from the floor) and in cases where the fan coil unit cannot be anchored
to the wall. The height of covering feet is 100 mm.
ZL / ZC - Pair of support covering feet for
GTFL, GTCL models
The ZL, ZC, covering feet, designed for the
installation on éstro GTFL, GTCL models are
supplied in pairs and comprise supports for
fastening to the base unit and outer coverings
for fastening to the cabinet.
They are used to conceal the plumbing (pipes
leading up from the floor) and in cases where the fan coil unit cannot be
anchored to the wall. The height of covering feet is 100 mm.
ZLG / ZCG - Pair of support covering feet with
front grille for GTFL, GTCL models
The ZLG, ZCG covering feet, designed for the
installation on éstro GTFL, GTCL models are
supplied in pairs and comprise supports for
fastening to the base unit, outer coverings for
fastening to the cabinet and the front covering
grille.
They are used to conceal the plumbing (pipes leading up from the floor) and
in cases where the fan coil unit cannot be anchored to the wall. The height
of covering feet is 100 mm.
9 ACCESSORIES
MYCOMFORT LARGE - Wall-mounted microprocessor
control, GALLETTI model MYCOMFORT LARGE
having the following main features:
- Room air temperature reading and adjustment.
- Room humidity reading and adjustment.
- Water temperature reading (water sensor as an
optional).
- Manual and automatic adjustment of fan speed.
- Manual and automatic switching of heating
and cooling mode depending on the water
temperature within the heat exchanger or on the room temperature, with
a neutral zone that can be selected in the range from 2° to 5°C.
- Clock and hourly timer-programmed operation.
- 2 analogue outputs for controlling modulating devices 0-10V.
- 2 digital outputs for controlling (On/Off) external devices (no-voltage
contacts).
- Serial port for Bus connection.
The controller is equipped with a large display (3”) to show and set all the
functions of the unit.
Using the installation kit available, mycomfort can be mounted on the unit.
EVO - Electronic microprocessor
controller with remote user
interface
Intuitive and user-friendly multi-
purpose regulator
EVO encompasses the best of
Galletti adjustment with regard to
hydronic indoor units.
The EVO software, which was
developed entirely by Galletti’s
Technical Department, consists
of two distinct parts in two
microprocessors. The first of these, resident on the power board, manages
the monitoring of the parameters and the adjustment logics. The second
part of the software, which is loaded on the user interface microprocessor,
guarantees true communication, by means of which the installer and the
user are guided in the configuration and use of the controller.
If on-board installation of the power board is requested, which is an option
that is available for the majority of Galletti hydronic indoor units, during the
wiring phase you just need to connect the user interface using a two-core
shielded cable. This extraordinary simplicity cuts installation time and costs
in half.
The EVO controller has been designed to govern the operation of Galletti
indoor units with single-phase multispeed asynchronous motor or
modulating speed BLDC motors. Specifically, its advanced technology
makes it possible to establish control networks that are suited to meet any
need, for automatic and intelligent management of the system’s indoor
units.
PLUS
Considerable savings in the installation phase
User-friendly interface
RS485 and OC serial communication
Advanced de-humidifying function
Simultaneous control of 3 modulating devices
Advanced control of time schedules
FUNCTIONS
Automatic control of time slots
The user interface makes it possible to set the ON/OFF status of the control
and the desired setpoint, on an hourly basis, for the different days of the
week. If the above-mentioned operating parameters are set on a master
unit, they can be replicated on all the connected slaves.
