The Ichill has to be configured to manage the remote keyboard.
Upper digits (red color): configurable by parameter CF44 (PB1, PB2, PB4, Set-point
(parameter value)*, working set-point (real set-point modified from dinamic set-point,
Energy saving or function for units without water storage tank), Hysteresis, Machine
status **))
Lower digits (yellow color): configurable by parameter CF45 (PB1, PB2, PB3, PB4,
Set-point (parameter value)*, working set-point (real set-point modified from dinamic set-
point, Energy saving or function for units without water storage tank), Hysteresis, RTC,
Machine status **)).
*the display visualizes chiller set point when the unit is on and in chiller mode, heating
set point when the unit is on and in heat pump mode, and OFF when the unit is in
standby.
**the display visualizes OnC when the unit is on and in chiller mode, OnH when the unit
is on and in heat pump mode, and OFF when the unit is in standby.
Note:
the Ichill 100CX is not compatible with VI610 remote keyboard.
Key Function
Concerning the meaning of the keys, refer to paragraph 2.3.
Air/Air unit: using the remote keyboard with NTC sensor on board (VICX610S model
and parameter CF35 = 2), the read-out and the regulation are controlled by the NTC
sensor mounted on the remote keyboard.
When there is not communication between the keyboard and the instrument the display
visualizes ”noL” (no link message).

ISPLAY VISUALIZATION
Upper digits (red color): configurable by parameter CF36 (PB1, PB2, PB4, Set-point
(parameter value)*, working set-point (real set-point modified from dinamic set-point,
Energy saving or function for units without water storage tank), Hysteresis, Machine
status **)
Lower digits (yellow color): configurable by parameter CF43 (PB1, PB2, PB3, PB4,
Set-point (parameter value)*, working set-point (real set-point modified from dinamic set-
point, Energy saving or function for units without water storage tank), Hysteresis, RTC,
Machine status **).
*the display visualizes chiller set point when the unit is on and in chiller mode, heating
set point when the unit is on and in heat pump mode, and OFF when the unit is in
standby.
**the display visualizes OnC when the unit is on and in chiller mode, OnH when the unit
is on and in heat pump mode, and OFF when the unit is in standby.
Alarm visualization
When the instrument detects an alarm, the lower display shows the alarm code
alternated to probe value. The alarm icon ( ) is on flashing.
In case of HIGH PRESSURE alarm (HP), LOW PRESSURE alarm (LP) or WATER
FLOW SWITCH (Flow!), dedicated icons are on.
STD-BY visualization
It is possible to choose what visualize when the Ichill is in STD-BY.
CF 46 = 0: the display visualizes the same informations configured in CF36 e CF43
CF 46 = 1: the display visualizes the label “OFF”
CF 46 = 2: the display visualizes the label “StbY”

NSTALLING
After giving power supply to the instrument, the lower display can show “rtC” alternated
to the probe value: it is necessary to set the clock time.
If the probes are not connected, or they are faulty, the display shows the corresponding
alarm code.
In any case it is possible to proceed with clock setting.
