ELECTRONIC CONTROL FOR TERMINAL UNITS
18
II.3.5.2 ON / OFF remote control (SCR)
Digital input D1.
It is possible to control the device from a remote consent by means of a
time switch or a centralized system (clean contact).
Entry is always enabled.

input
Polarity
/ / D1
Open = unit on (ON)
Closed = unit turned off (OFF)
When the contact is reopened, the machine resumes operation with the
last settings.
OFF appears flashing on the control panel.
The connection between the board and the remote switch must be
carried out with a shielded cable consisting of 2 twisted conductors of
0.5 mm² and the shield (type Belden 8762 20 AWG). The screen must
be connected to the GND.
The maximum distance is 10m.
Digital inputs between different boards can not be connected in parallel.
Use the clean contacts of an external relay (not supplied).
II.3.5.3 SUMMER / WINTER remote control (EIR)
Digital input D2 or D3.
The operating mode of the device can be controlled by a remote
consent (dry contact) via a closed / open switch or a centralized system.

Open = unit in heating
Closed = unit in cooling
The MODE key on the control panel is disabled, the display shows the
operating mode symbol controlled by a digital input.
The connection between the board and the remote switch must be
carried out with a shielded cable consisting of 2 twisted conductors of
0.5 mm² and the shield (type Belden 8762 20 AWG). The screen must
be connected to the GND.
The maximum distance is 10m.
Digital inputs between different boards can not be connected in parallel.
Use the clean contacts of an external relay (not supplied).
II.3.5.4 SECURITY control (SIC)
Digital input D2 or D3.
It is possible to subordinate the operation of the unit to a remote
consent (clean contact). For example, it is possible to interrupt the
operation of the unit when a window is opened by means of a contact
placed on it.

If the contact is opened, the machine goes into the OFF position and
the flashing On / Off display appears on the control panel.
When the contact closes again, the machine resumes operation with
the last settings.
The connection between the board and the remote switch must be
carried out with a shielded cable consisting of 2 twisted conductors of
0.5 mm² and the shield (type Belden 8762 20 AWG). The screen must
be connected to the GND.
The maximum distance is 10m.
Digital inputs between different boards can not be connected in parallel.
Use the clean contacts of an external relay (not supplied).
II.3.5.5 ECONOMY (ECO)
Digital input D2 or D3.
It is possible to operate the unit in ECONOMY mode by a remote
consent (clean contact).
The input is enabled by parameter H12 or H13.

H12 4 D2
Open = Eco function not activated
Closed = Eco function activated
H13 4 D3
Open = Eco function not activated
Closed = Eco function activated
In Economy mode, the fan is forced at minimum speed and the working
temperature values ??are optimized in order to achieve energy savings.
In the "cooling" mode the temperature is increased by one degree, in
the "heating" mode the temperature is decreased by one degree.
If the Economy function is activated, no symbol on the control panel
identifies the active function.
The Economy function is active in all operating modes.
The connection between the board and the remote switch must be
carried out with a shielded cable consisting of 2 twisted conductors of
0.5 mm² and the shield (type Belden 8762 20 AWG). The screen must
be connected to the GND.
The maximum distance is 10m.
Digital inputs between different boards can not be connected in parallel.
Use the clean contacts of an external relay (not supplied).
II.3.5.6 ALARM (ALL)
Digital input D2 or D3.
It is possible to block the operation of the device through a digital input
configured as a remote alarm (clean contact) by means of a closed /
open switch or a centralized system.
The input is enabled by parameter H12 or H13.

E06 flashes on the control panel.
If an Off call occurs during the block, the fan coil is forced to switch off
(the display shows the Off status). At the next On call, the fancoil
returns to the previous state of alarm (the display shows E06).
When the contact is closed, the machine resumes operation with the
last settings.
The connection between the board and the remote switch must be
carried out with a shielded cable consisting of 2 twisted conductors of
0.5 mm² and the shield (type Belden 8762 20 AWG). The screen must
be connected to the GND.
The maximum distance is 10m.
Digital inputs between different boards can not be connected in parallel.
