Vh Vc Alarm 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
- Alarm: 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
- Dehum: dehumidifi cation 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 tem-
perature 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 control-
ler via the probe associated with the temperature probe
used
■ "Water Temperature" register: value read by the water
probe (SW)
■ "P00" Register: "Controller confi guration" 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 correc-
tions based on economy logics,...or use of the setpoint
imposed by the supervision software)
■ "LCD version" Register: defi nes the controller type and
software version installed (0xHHSS: HH: ASCII character,
SS:sw version)
■ "P09" Register: "Digital output 1 Confi guration" parameter
■ "P10" Register: "Digital output 1 Logic" parameter
■ "P11" Register: "Digital output 2 Confi guration" parameter
■ "P12" Register: "Digital output 1 Logic" parameter
■ "P14" Register: "Confi guration 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

- - Lock MinT
- On/Off: On/Off via supervision system
- S/W: selection of operating mode via supervision system
(0: Cooling, 1: Heating); N.B.: if the unit confi guration
(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 Electrical heater 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 electrical heater function
via supervision system
- En.ECO: enabling of economy mode activation via super-
vision system
- En.MinT: enabling of selection of Minimum Temperature
logic via supervision system
- En.Set: enabling of forced override of setpoint via super-
vision system
- En.Min/Max: enabling of setpoint thresholds via supervi-
sion 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 su-
pervision system for the Cooling mode
■ "Heating - Setpoint" Register: setpoint imposed by su-
pervision 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 operation ; 2=automatic fan operation
