Comfort Functions; Ii.3.10 Advanced Functions - RHOSS KCMS/PCM Série Mode D'emploi

In the c ase of the KICM panel, the electrical resistance (is declar ed to
be present) is acti vated by setting the HEAT func tion.
IMPORTANT !
In order to counter the air stratification
phenomenon, the termin al unit performs fan start-
up/switch-off cycles at minimum sp eed even when
the room temper ature has reach ed the set-point
(the hot/cold valve rem ains closed). This h elps the
room temperature be d etected correctly if the
terminal prob e is not used (ST 1 adjustment probe).
If the adjustment is performed with the terminal
probe, the function is deactivated.

COMFORT FUNCTIONS

II.3.9.1 TOO COOL
The COOL and DRY operating modes require the TOO COOL func tion
that bloc ks the fan from s tarting up if the water temperature entering the
exc hanger is over 18°C, thereby preventi ng unpleas ant flows of hot air.
This could occ ur when the unit is s tarted up after a long break.
The DIP1 must be set to ON.

II.3.9.2 HOT S TART
The HEAT operating mode requires the HOT START func tion that
bloc ks the fan from starti ng up if the water temperature entering the
exc hanger is bel ow 32°C at mi nimum s peed, 36°C at medium s peed
and 40°C at maximum s peed, thereby preventi ng unpleas ant flows of
cold air. T his coul d occ ur when the unit is started up after a long break.

at minimum speed, which is equal to the perc entage given by
P129

if the water temperature exc eeds P12+P13, adjus tment is allowed

II.3.9.3 MEMORY
After a power cut, the applianc e will restart in the mode it was operati ng
in at the moment the power c ut occurred. If the TIMER or SLEEP
functi on was acti ve before the power c ut, this is deacti vated.
MEMORY is also acti ve in the remote ON/OFF control and SECURITY
control func tions.

II.3.10 ADVANCED FUNCTIONS

II.3.10.1 Master/slave connection
This is a special functi on whereby an appliance defined as Master
sends infor mati on regardi ng the current operation to other appliances
(maximum 5) defined as Slave ( which do not have a c ontrol panel), via
an electrical connection, whic h must be s et up during the ins tallati on
(see wiring diagrams).
All the units can be adjusted vi a the c ontrol panel of the Mas ter in two
different ways :
if "Probe out" appears on the c ontrol panel and FULLAUTO or a
manual mode is set, each Slave applianc e is adjusted by its own
room air probe;
if "Probe in" appears on the control panel and FULLAUTO or a
manual mode is set, each Slave applianc e is adjusted by the room
air probe inside the c ontr ol panel (the Slaves repeat the Master
operation).
Control panel: dis plays onl y the Mas ter status .
Alarms: the al arms are managed separately in ever y control boar d.
Inputs: All the digital inputs of the Master are always ac tive. T he digital
inputs of the Slave's ECO, EIR and LOCK FUNCTION ar e dis abled:
SCR and SIC remai n ac tive.
The SCR on the Master bloc ks the entire chain; the SCR on the Slave
onl y stops the relati ve slave unit.
The SCR is s epar ate, i.e. it only stops the r elati ve unit (mas ter or slave).
