TECHNICAL MANUAL

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.

Covering plates available in three colours matching the 503 connectors.

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 ventilation (if present, as support in heating

mode) and the automatic cooling/heating changeover according to the water temperature.

PMA / PMAC - plenum for the connection to flexible dutcs

PMAD e PMACD (insulated) plenums are used to connect to air distribution plants achieved by means of hoses or to other dedicated accessories. They can be

installed on both the intake and delivery line (in this case the hose should be insulated). The spigot diameter is Ø 200 mm.

PAF - Front air intake plenum Ø200

Thanks to the accessories " PMA outlet plenum" and " PAF front intake plenum " it is possible to include DM in installations where it is necessary to have the air outlet

and inlet on a single side, thus considerably reducing the required space. The air intake is equipped with Ø 200 collars

RD / RDC - Suction/delivery straight connection

Are used to connect the unit DUCTIMAX to rectangular air distribution ducts or directly to GM and GA air outlet and intake grilles
