- - Lock MinT Eco RE S/W On/Off
-
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 con fi 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

“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 con fi 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)
■
“
