■ P04 = water
sensor
-0: not available
-1: available
Based on the set value, the sensor alarm and the electrical
heater functions will be controlled
■ P05 = use confi guration DIN 1/2
- 0: DIN1 = - DIN2 = -
- 1: DIN1 = - DIN2 = OnOff
- 2: DIN1 = Sum/Win DIN2 = -
- 3: DIN1 = Eco DIN2 = -
- 4: DIN1 = Sum/Win DIN2 = On/Off
- 5: DIN1 = Eco DIN2 = On/Off
- 6: DIN1 = Sum/Win DIN2 = Eco
■ P06 = DIN1 logic:
- 0: [open/closed] = [Cooling/Heating] = [-/ECO]
- 1: [open/closed] = [Heating/Cooling] = [ECO/-]
■ P07 = DIN2 logic:
- 0: [open/closed] = [OFF/ON] = [-/ECO]
- 1: [open/closed] = [On/Off] = [ECO/-]
■ P08 = Remote humidity sensor
- 0 : not available
- 1 : available
Based on the set value, the associated probe alarm will
be triggered accordingly.
■ P09 = DOUT1 confi guration:
- 0 : not used
- 1 : indicating operation mode
- 2 : indicating unit cooling/heating mode
- 3 : indicating unit cooling mode
- 4 : indicating unit heating mode
- 5 : indicating ON/OFF
- 6 : indicating sensor alarm triggered
- 7 : external dehumidifi cation active
- 8 : external humidifi cation active
- 9 : indicating high room temperature
- 10 : indicating low room temperature
- 11 : not used
- 12 : indicating low water temperature
(see “Confi guration of digital outputs”)
■ P10 = DOUT1 logic:
- 0 : not used
- 1 : indicating operation mode
(see “Confi guration of digital outputs”)
■ P11 = DOUT2 confi guration: same as parameter P09 but
for digital output 2.
(see “Confi guration of digital outputs”)
■ P12 = DOUT2 logic: same as parameter P10 but for digital
output 2.
(see “Confi guration of digital outputs”)
■ P13 = room relative humidity SETPOINT (see “Confi guration
of digital outputs)
■ P14 = AOUT1/2 confi guration: confi guration of the two
analog outputs 0-10V depending on the type of fan ( non-
modulating or modulating) and the type of valve(s) (ON/
OFF or modulating). For further details see “Confi guration
of analog outputs”.
KEY BOARD (SEE FIGURE 3)
On/Of
f key: Thermostat On/Off. During the
procedure of parameter modifi cation, it permits to
return to normal operating conditions
Up and Down keys: changing of thermostat set-
ting temperatur
e (Heating: [5.0-30.0°C], Cooling:
[10.0-35.0°C]). During the procedure of parameter
modifi cation, they are used to select the parameters
or to change their value
SEL key: in the heating mode, the electric electrical
heater can be selected as auxiliary function
Mode key: selection of Heating/Cooling operating
mode
Fan key: selection of operating speed
EC key: selection of Economy mode
ACTIVE KEY COMBINATIONS
■
with OFF thermostat: access to circuit board confi guration
parameters (password=10)
■ with thermostat ON: display of current water temperature
(if air sensor is present and correctly confi gured through
parameter P04) and hour set on the internal clock
■
selection of Minimum temperature function
■ selection of dehumidify option
■ keypad locking/unlocking (passwor
d=99);
■ access to time pr
ogramming parameters (password=5)
In any display mode other than the normal one, about 2 mi-
nutes after the last button was pressed the controller will go
back into the standard display mode.
BOARD CONFIGURATION
The boar
d can be confi gured according to the type of unit/
system to be governed by changing some parameters.
PARAMETER LIST
■
P00
= controller configuration (see “Available
confi gurations”) to select the type of unit to be managed.
■ P01 = type of controller installation
-000: on the unit
-001: wall mounted
■ P02 = Modbus address. In order for the change in this
parameter to become active (excepting in the case of
internal transfer between slave values) it is necessary
to switch the power off and back on again at the end of
programming):
-0: serial communication disabled
-1-247: Slave
-255: Master
■ P03 = neutral zone [20-50°C/10]; parameter used in case of
confi gurations with automatic cooling/heating changeover
according to air temperature.
