Different types of remote controls can be used depending on the number of units to be controlled.
Individual remote controls
• Recommended to be always installed for the local control of each unit.
• The indoor units should be grouped in remote control groups with a maximum of 16 indoor units for each group.
Centralised remote controls
• Centralised remote controls are suitable for controlling a high number of indoor units distributed throughout a whole
oor of a building. Anyway, several oors can also be controlled by these type of controls.
• The indoor units are grouped in different remote control groups, and the maximum number of groups is different de-
pending on the device.
Building AC controls (CSNET WEB and CSNET Manager)
• These controls are recommended for installations with a high number of indoor units distributed through several oors
which need to be separately controlled.
• The devices PSC-A60WEB1 and HC-A64NET can be installed at any point of the building. They can be connected to
the CSNET Manager screen for centralised control of the building.
• PSC-A160WEB1 is accessible from any computer inside the building which has the CSNET WEB software installed.
Connection from outside the building can also be performed by conguring properly the network settings.
• CSNET WEB and CSNET Manager are both accessible from inside/outside the building through a web browser if the
network conguration is properly set-up.
Building management system (BMS)
• Recommended for use in intelligent buildings with integral control systems (building automation, security, access, etc.).
• Building Management systems (BMS) are based on information transmission protocols like LONWORKS, MODBUS
KNX, BACNET or FIDELIO.
• There are two different methods for controlling the units:
- Via Building AC controls (CSNET WEB or CSNET MANAGER) with the protocols MODBUS, FIDELIO or KNX
(through CSNET WEB only for the latter).
NOTE
BMS is connected to CSNET WEB and CSNET Manager, thus all their advantages can also be used in this system
control.
- Via direct connection with the protocols BACNET, LONWORKS, KNX or MODBUS.
NOTE
BMS control is limited to the building control room.
