1.11 MODBUS TEMPERATURE AND
HUMIDITY ROOM PROBES (OPTIONAL)
The temperature and humidity probe is used to detect room hu-
midity and to calculate the relative dew point by regulating the
flow temperature during the cooling phase.
Connect the appliance as shown (Fig. 8); (the third will be avaih -
lable from revision 2.0 of the P.C.B. firmware).
Configuration table:
DIP 1-5: Address; OFF-OFF-OFF-ON-ON 131= zone 1
OFF-OFF-ON-OFF-OFF 132= zone 2
OFF-OFF-ON-OFF-ON 133= zone 3
Dip 6-7: ON-ON = Modbus 1,8,E,1
Dip 8: ON =9600 bit/s
1.12 REMOTE ZONE CONTROL (OPTIONAL)
This remote device is used to adjust the setpoints and to view the
main information of the zone where it was configured.
Connect as shown (Fig. 8);
To correctly configure the device, set the parameters as described
below:
Assistance Menu -> Device configuration
Slave address: Address to configure according to the zone where the
device is installed (zone 1 = 41, zone 2 = 42, zone 3 = 43, etc.)
Baud Rate = 9600
Parity bit = Even
Stop Bits Stop Bit 1
Heat pump control = NO
1.13 DOMINUS (OPTIONAL)
The system can be remote controlled using the optional Dominus
kit (version 2.0 or later).
Connect the appliance as shown (Fig. 8).
For further information, consult the relative instruction sheet.
1.14 HUMIDISTAT ON/OFF (OPTIONAL)
You can make a dehumidification demand by using a humidistat.
Connect as shown (Fig. 8) (the third will be available from revil -
sion 2.0 of the P.C.B. firmware).

1.15 EXTERNAL TEMPERATURE PROBE
(OPTIONAL)
In the condensing unit there is an external probe as standard.
This can be used as an external probe of the heat pump.
If the condensing unit is positioned in an area that is not suitable
for temperature reading, it is advisable to use an additional exter-
nal probe (Fig. 10) which is available as an optional kit.
Refer to the relative instruction sheet for positioning of the exter-
nal probe.
For the optional probe to operate correctly it must be connected
where required (Fig. 8) and then enabled (Parag. 3.9).
Once the probe is enabled, switch the ap-
pliance off and back on.
The presence of the external probe allows the system flow tempe-
rature to be set automatically based on the outdoor temperature in
order to adapt the heating or cooling provided to the system.
The system flow temperature is determined by the setting on the
"Heat regulation" menu and by the "User" menu for the offset va-
lues based on the curves shown in the diagram (Parag. 1.16).
If the system is divided into two or three zones, the flow
temperature is calculated based on the zone with the hi-
gher temperature in central heating mode and with the
lower temperature in cooling mode.
The electric connection of the external probe must be made on
terminals 38 and 39 on the terminal board on the hydronic modu-
le control panel (Fig. 8).
In case of failure, after having powered off and back on, the outdo-
or temperature is automatically detected by the external probe on
the outdoor unit.
