EVO controller
Default value 0. It represents the percentage speed value of the fans to be added to the one set to obtain the
DFans
desired increase during dehumidification. For example, if the fan speed is 20% and this parameter is set to 30%,
000%->100%
when the dehumidification is enabled, the speed changes to 50% (20 + 30). If the machine is set to work under
000Pa
pressure or constant flow, this value is expressed in Pascal or in cubic meters now. The value to be passed
0000m³\h
depends on the set full scale. For 3-speed units, it is expressed in simple numerical form (0-1-2-3) corresponding to
0-1-2-3
the next speed increment to be set.
It is available a version of touch panel which support protocol Modbus Tcp-ip or Modbus RTU by an additional card (see control panel
wirings paragraph) .In this item of menu installer is possible to change configuration parameters :
Default
Restore the factory default values.
Modbus
Allow the user to choose between Modbus Tcp-ip or Rs485 (additional card).
Address
Only for RS485 protocol. It is the address of the unit (default=1).
Baud rate
Only for RS485 protocol. It is the baud rate of serial communication (default =9600).
Parity
Only for RS485 protocol. It is the parity value of the serial communication (default=even).
Stop bits
Only for RS485 protocol. It is the bits stop value of the serial communication (default=1).
Conn . to (s) 10sec
It is the reading time of the modbus registers. This value indicates the maximum time after which, if no registers are accessed from the
master device, the changes made by the modbus are reset. You can disable it, but for safety reasons the reset will take place anyway
once the machine is switched off.
IP0.IP1.IP2.IP3
It is the ip address of the unit (default=192.168.1.243 modifiable).
NM0.NM1.NM2.NM3
It is the subnet mask address of the unit (default=255.255.255.0 modifiable).
GW0.GW1.GW2.GW3
It is the gate away address of the unit (default=192.168.1.1 modifiable).
Reset
After changing of any address through reset the modify is confirmed without power cycle the unit. IP address

1 stop bit,
parity even,
disconnection after 10 sec without access to the registers. (modifiable via MODBUS)
close jumper on rs485 card ,insert if the unit is at the end of bus line..
Web server
A Web server installed allows us to monitor the machine status and change its parameters permanently through the PC. In order for
the connection with the Web server to be successful, the initial three fields of the IP address must match. For instance, if your address
is 192.168.1.243, the PC address must be 192.168.1.xxx. To start the web server after connecting the machine to the web, start your
browser and type http\\192.168.1.243 (or the address modified) in the address bar.
