DESCRIPTION OF READ-ONLY REGISTERS [R]
 " STATUS" register
Bit 15 Bit 14 Bit 13 Bit 12
DOUT2 DOUT1 P04 Deum
Bit 7 Bit 6 Bit 5 Bit 4
Vh Vc Allarme MinT
On/Off: unit status (0: Off, 1=On)
-
S/W: operation mode (0: S=cooling,1:W=heating)
-
P01: "on unit/wall-mounted" parameter
-
- Eco: Economy logic active
Min.T: Minimum Temperature logic selected
-
Allarme: general alarm indication (activated when any of
-
the managed alarms is triggered)
- Vc: status of digital output Vc
Vh: status of digital output Vh
-
DI1: logical value of dig. input 1 (the physical status of the
-
input depends on the associated logic)
- DI2: logical value of dig. input 2 (the physical status of the
input depends on the associated logic)
P07: "DIN 2 Logic" parameter
-
P06: "DIN 1 Logic" parameter
-
- Deum: dehumidification ON (0:no, 1:yes)
- P04: "water probe present" parameter
DOUT1: Digital Input 1 status
-
DOUT2: Digital Input 2 status
-
 " SPEED" register: current operating speed of the indoor
unit
- 0: fan OFF
- 1: extra-low speed
- 2: low speed
- 3: medium speed
- 4: high speed
 " AIR TEMPERATURE" register: room temperature read
by the controller and shown on the display (N.B.: this
temperature corresponds to the reading of the remote
probe if the controller is located on the unit, or the reading
of the internal probe in the case of a wall-mounted controller
and remote probe disconnected).
 " HUMIDITY" register: room humidity read by the controller
via the probe associated with the temperature probe used.
 "WATER TEMPERATURE" register: value read by the
water probe (SW).
 " P00" register: "Controller configuration" parameter.
 " T. ACTIVE SETPOINT" register: setpoint used for
temperature control.
 " T. USER SETPOINT" register: setpoint programmed
by the user (it may differ from the active setpoint due
to corrections based on economy logics,...or use of the
setpoint imposed by the supervision software).
 " LCD VERSION" register: defines the controller type and
software version installed (0xHHSS: HH: ASCII character,
SS:sw version).
 " P09" register: "Digital output 1 Configuration" parameter
 " P10" register: "Digital output 1 Logic" parameter
 " P11" register: "Digital output 2 Configuration" parameter
 " P12" register: "Digital output 1 Logic" parameter
 " P14" register: "Configuration of analog outputs" parameter
 " Analog output 1" register: value of analogue output 1
expressed as a % of the full scale 0-10V
 " Analog output 2" register: value of analogue output 1
expressed as a % of the full scale 0-10V

Bit 7 Bit 6 Bit 5 Bit 4
- - Lock MinT
On/Off: On/Off via supervision system
-
S/W: operation mode via supervision system (0: Cooling,
-
1: Heating); N.B.: if the unit configuration (parameter P00)
provides for summer/winter changeover based on water or
air temperature, the resulting mode selection will override
the command from the supervision system (which is thus
substantially ignored)
- RE: selection of Heating element via supervision system
Eco: Economy mode ON via supervision system
-
MinT.: enabling of Minimum Temperature control via
-
supervision system; N.B.: actual activation remains at
the local discretion of each fan-coil unit based on the air
temperature probe reading.
Lock: keypad lock (0: unlocked, 1: locked)
-
En.On/Off :enabling of On/Off control via supervision
-
system
- En.S/W: enabling of mode control via supervision
system
En.RE: enabling of selection of heating element function
-
via supervision system
- En.ECO: enabling of economy mode activation via
supervision system
En.MinT: enabling of selection of Minimum Temperature
-
logic via supervision system
- En.Set: enabling of forced override of setpoint via
supervision system
En.Min/Max: enabling of setpoint thresholds via
-
supervision system
- En.Vel: enabling of selection of fan speed via supervision
system
 " Scheduling" register: ON/OFF time programming via
supervision system
- 0: scheduling disabled
- 1: scheduling enabled for ON/OFF
- 2: scheduling enabled with SETPOINT
 " COOLING - SETPOINT" register: setpoint imposed by
supervision system for the Cooling mode
 " HEATING - SETPOINT" register: setpoint imposed by
supervision system for the Heating mode
 " MINIMUM SETPOINT - COOL." register: lower limit for
setpoint in cooling mode
 " MAXIMUM SETPOINT - COOL." register: upper limit for
setpoint in cooling mode
 " MINIMUM SETPOINT - HEAT." register: lower limit for
setpoint in heating mode
 " MAXIMUM SETPOINT - HEAT." register: upper limit for
setpoint in heating mode
 " SPEED" register: selection of fan speed via supervision
system; in the case of modulating fan control, it expresses
the percentage of speed used in the manual mode
 " ECONOMY CORRECTION" register: correction of
setpoint in the case of economy mode imposed by
supervisor (this correction is an amount subtracted from
or added to the setpoint, based on the operating mode)
 " Modulating fan mode" register: selection of the mode
in the case of modulating fan control: 0 = fan OFF; 1 =
manually forced fan; 2 = automatic fan operation
