CRR units with IRC electronic board

Multifunction control

Another option available for the serial communication between the

units is the possibility to connect up to 60 Carisma units in series (the

maximum length of the connection cable must not exceed 800 m)

and manage them with just one wall-mounted intelligent PCR-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. If more than 60 units need to

be connected, two or more wall-mounted intelligent controllers must

be used. Each wall-mounted controller only manages the units it is

connected to.

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

a maximum of 60 units, from one single control point. The PCR-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

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 PCR-DI panel can also be used for the time management of the units over the week.

Two on times and two off times can be set on the units for each day of the week.

The weekly programming mode can be stopped at any time, returning to the manual setting and then weekly

programming mode can subsequently be started again.
