Another option available for the serial communication between

the units is the possibility to connect up to 60 Cassette units in

series and manage them with just one wall mounted PSM-DI

controller. The wall mounted controller can be used to set the

operating mode for each individual unit connected, display

the operating conditions of each individual unit, and set the

ON/OFF time sets for each day of the week (the program

can be set for all the units and for a maximum of two groups

of units).

If more than 60 units need to be connected, two or more

controllers must be used. Each wall mounted controller only

manages the units it is connected to.

The PSM-DI control is used to manage a series of fan coils,

up to a maximum of 60 units (the maximum length of the RS 485

connection cable must not exceed 800 m), from one single control point.

The PSM-DI control communicates via a serial line with all the units connected, with the possibility of controlling

them all together or individually. In fact, the unique address of each individual fan coil means that all the units can

be called at the same time, or the individual unit called, to perform the following functions:

- display the current operating mode, the fan speed, the set point;

- display the room temperature measured on the individual unit;

- turn all the units ON and OFF at the same time or alternatively each unit individually;

- change the operating mode (fan only, heating, cooling, automatic changeover);

- change the set point;

- modify the values and operation parameters of the fan speed.

Each function can then be sent to all the units connected, or alternatively to each individual unit.

Different set points or operating modes can be set for each individual unit.

The PSM-DI panel can also be used for the time management of the units over the week. Four ON times and four

OFF times can be set on the units for each day of the week. A different Temperature set that will be considered as

Operation set for all connected appliances, can be set for each event. If the Temperature set is not entered for the

individual event, it must be set during programming for each individual unit or for the entire network.

Units without receiver or with receiver can be connected within the network: the former can receive instructions only

from the PSM-DI wall mounted panel; while the latter can receive information from both the wall mounted panel

(PSM-DI) and infra-red remote control. Use the infra-red remote control to force ON mode of the individual unit,

if ON/OFF daily time programming has been set. The unit will regain the settings from the PSM-DI panel during

execution of successive start-up program.

The PSM-DI panel cannot be used

Note: set the configuration Dip Switches of each fan coil as illustrated in the remote control use manual, based on

the required solutions.
