RHOSS KCMS/PCM Série Mode D'emploi page 42

Dip-Switch : only Dip Switch 1-4-5-6 is considered in the Slaves.
Timeout: The Slaves cannot continue to r un without the Master (due to
no c ommunication, a fault, etc .) as no c ommand coul d be given to the
mac hines (On/Off, etc.).
Therefore, if no message is rec eived from the Mas ter for 8 s, the slave
is switched off.
The maxi mum distanc e of the loc al networ k is 30 m (the distanc e
between the Master and the l ast Sl ave).
The connection between the Master and the Slave must be c arried out
with a s hielded c able c onsisti ng of 2 twisted 0.5 mm² conduc tors and
the s hield. The shiel d must be connec ted to the earth screw.
II.3.10.2 ON/OFF remote control (SCR)
The appliance c an be controlled from remote consent via a time switc h
or a centralised s ystem ( potenti al-free c ontact).
Unit is ON
Unit is OFF
When the c ontact is r eopened, the mac hine restarts with the mos t
recent s etti ngs.
REMOTE CONTROL appears on the c ontrol panel.
Note: The maximum cable length allo wed is 30 m with an AW G 14-
22 section.
II.3.10.3 SUMMER/WINTER remote control (EIR)
The appliance operating mode c an be controlled from remote consent
(potential-free contact) via a cl osed/open contac t or a centralised
system.
The input is enabl ed by the DIP-Switch 2 (see paragraph 0).
The MODE key of the c ontrol panel is disabl ed and LOCK FUNCTION
appears on the displ ay.
Heating mode
Cooling mode
Note: The maximum cable length allo wed is 30 m with an AW G 14-
22 section.
II.3.10.4 SECURITY control (SIC)
Unit operation can be c ontr olled fr om r emote cons ent (potential-free
contact). For example, unit operation can be interrupted when a window
is opened by a c ontact on the window itself.
Any TIMER – SLEEP func tions are deacti vated.
Unit is ON
Unit in al arm status
If the contact is clos ed, the mac hine is s et to OFF and A07 appears on
the c ontr ol panel.
When the c ontact is r eopened, the mac hine restarts with the mos t
recent s etti ngs.
Note: The maxi mum c able l ength allowed is 30 m with an AWG 14-22
section.
II.3.10.5 ECONOMY (ECO)
The unit c an run in ECONOMY mode from remote consent (potential-
free contact).
When in Economy mode, the fan is forced to the minimum speed, the
brightness of the LEDs is reduc ed and the operating temperature
val ues are opti mised for energy savi ng purposes. The temperature is
increased by 1 degree when in the "cooling" mode and decreased by 1
degree when i n the "heating" mode.
If the Ec onomy function is acti vated, the SLEEP key is disabled and the
Sleep s ymbol appears on the control panel.
The Ec onomy function is acti ve in all operati ng modes.
Eco functi on is not

II.3.10.6 LOCK FUNCTION
Allows res tricted management of the applianc e in the cas e of centrall y
managed applications (restricted air conditi oning).
The functi on is enabled with the Dip-Switch 3 (see paragraph0).
It only allows the FULLAUTO mode (or possibl y EIR, if enabled).
The other possible functions ar e:
switching the unit on and off;
change the Set-poi nt by ±3°C (onl y if the Comfort Contr ol function
is enabled);
change the fan s peed ( min-med-max-AUTO);
enable the CONT function;
If the EIR function is acti ve, the operating mode depends on the status
of the digital input.
LOCK FUNCTION appears on the c ontrol panel.
II.3.10.7 Comfort Control
In some installations , the Set-point is deci ded
by the s ystem manager. In these c ases, the
user can increase or reduce the Set-poi nt val ue
by 3°C to c ompensate for the difference i n
temperature. The modification is done from the
UP and DOW N keys and is displ ayed for 5
seconds.
Note: the function must be acti vated by setti ng parameter P36=1.
Note: i n the c ase of a recess ed panel, use a PCM panel "temporaril y" to
change the parameter.
The default s witch- over set is 22°C.
II.3.10.8 Occupancy function (only for KICM)
The rec essed panel onl y allows the room to be air conditioned when it
is occupi ed. Simply press the Sleep key or wait for the sensor (if
installed) to detect the pres ence for the s ystem to be acti vated.
Not occupied
In this case, there is no one in the room that is to
be air conditioned. The room is air conditioned
with a Set-point that allows for energy savings.
Occupied
In this case, there is s omeone in the room that is
to be air c onditi oned. T he room is air c onditi oned
according to the c onfigured Set-poi nt.
Note: the function must be acti vated by setti ng parameters P45=8,
P93=3 by means of the installer pass word on the panel.
