EVO - wall-mounted microprocessor split controller with display
EVO controller is a system composed of:
• Circuit board comprising the power circuit, the microprocessor system and the removable screw connectors for the connection
of the inlet and outlet devices;
• User interface comprising a graphic display and a keyboard (six keys) provided with clock and sensor to read the ambient
temperature.
Main functions:
• Room air temperature reading and adjustment
• Room humidity reading and adjustment
• Water temperature reading (water sensor as an optional)
• Manual/automatic regulation of the fan speed with ON -OFF step and modulating control
• Automatic adjustment of valve opening with ON/OFF and modulating controller
• 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 selectable neutral zone
• Clock and hourly timer-programmed operation
• 3 Analogue outputs for controlling modulating evices -10V
• E conomy function and minimum temperature
• 1 Digital outputs for controlling (On/Off) external devices (novoltage contacts)
• Serial port for RS485 connection
• Serial port for OC connection
• 3 digital inputs for ON-OFF, Economy, Operating mode remote setting
Operating mode
The controller is provided with a programmable display that allows you to view and set the hydronic unit functions by means of
the specific interface with parameter description.

LED503 - Recess wall-mounted microprocessor control
The proposed microprocessor control panels for Galletti indoor units is completed by the LED503 command with LED display that
is designed for recess wall mounting.
CONTROLLER
The control software developed by the Galletti Software Dept., features:
• Manual fan speed selection
• Automatic selection of fan speed according to the difference between the set temperature and the room air temperature
• Manual selection of heating/cooling operating mode;
• automatic selection of heating/cooling operating mode;
• Control of 1 or 2 ON/OFF valves;
• Control of additional heating element;
• on board timer function to detect the actual ambient air temperature;
• Reading of air ambient temperature, set point, fan speed and mode selection on the LED display.

MCSWE - water temperature sensor for microprocessor controls model EVO, MYCOMFORT
Directly connected to the microprocessor controllers EVO and MYCOMFORT to measure the water temperature through the heat
exchanger.
If the temperature registered is lower than 17 °C the unit works in cooling mode and the temperature range of the control panel
will be referred to the cooling mode (19/31 °C); if the temperature registered is higher than 37 °C the unit works in heating mode
and the temperature range of the control panel will be referred to the heating mode (14/26 °C). If the temperature registered is
between 17 °C e 37 °C the control panel will disable the unit operation.
MCSUE - Humidity sensor for EVO and MYCOMFORT microprocessor controller
Directly connected to the microprocessor controllers EVO and MYCOMFORT, it enables the control of the heating element ventila-
tion (if present, as support in heating mode) and the automatic cooling/heating changeover according to the water temperature.
NAVEL - Device for Wi-Fi or Bluetooth communication between EVO BOARD and smartphone
device for connect hydronic unit with control EVO to a WI-FI network or BLUETOOTH local device for remote or local management
by GALLETTI APP dedicated.
