CONNECT TO NETWORK
The device can connect to a PC via network RS485 or to a Remote Control via four cables.
Connect to a PC: CAMIN software can monitor all temperatures, compressors relays, alarms, parameters, while sending SMS and emails in case of an alarm.
More than 250 devices can connect to this network.
Connect to a Remote Control device: it displays on screen whatever is displayed on the main device and it has full access from the keyboard to the main device.
It can be installed up to 500 meters away from the main device.
PARAMETERS
Parameters are separated in two groups: 120 main parameters and 16 secondary parameters (A1-A16). Two of the main and 16 of the secondary parameters are easy
accessible. For the rest we have to enter in the parameter Cod = 22 to have access to all the parameters
.
Check relevant table on page 2.

Maximum consumption for each device 10 Watt
ON/OFF DEVICE
Press
for 4 seconds to toggle the device between
ON/OFF
state if the parameter is set to
Grc=0
.
If ON-OFF input No 15 is activated or if the parameters are under programming, this function is canceled.
HEATING – COOLING OPERATION
Press
for 4 seconds to toggle the operation between heating and cooling or cooling and heating mode if parameter is set to
GrH=0.
If the input No 16 Heating-Cooling is activated or the parameters are under programming, this operation is cancelled.
dFrost
Pressing the SET button for 5 sec starts dFrost on both circuits. The display shows the message dF1 and dF2 every 2 sec, for a fraction of a second, which means that
circuits 1 and 2 do dFrost.
RESET ALARMS
Pressing
to reset the alarms: this feature is active even during programming the parameters.
PROGRAMMING PARAMETERS
