1. SECURITY RULES
CAREFULLY OBSERVE ALL THE FOLLOWING INSTALLATION INSTRUCTIONS TO ENSURE
PERSONAL SAFETY. IMPROPER INSTALLATION CAN SERIOUSLY ENDANGER SAFETY.
MANDATORY RISK ANALYSIS AND PROTECTION MEASURES.
The Nekos electrical actuators comply with the Machinery Directive (2006/42/EC), Standard
IEC 60335-2-103 (Particular requirements for drives for gates, doors and windows) and
other directives and regulations indicated in the attached Declarations of Incorporation and
CE Conformity (at the end of the manual). According to the Machinery Directive, actuators
are “partly completed machinery” intended for incorporation into doors and windows. The
manufacturer/supplier of the window is required, with exclusive responsibility, to ensure the
compliance of the entire system with the applicable standards and to issue CE certification.
We strongly discourage any use of the actuators other than that specified and therefore, in
any case, the supplier of the complete system retains full liability.
For systems installed at a height of less than 2.5 m above floor level or other levels
accessible to users, the manufacturer/supplier of the window must conduct risk analysis
regarding potential harm (violent blows, crushing, wounds) caused to people by normal use
or possible malfunction or accidental breakage of the automated windows, and to
implement suitable protective measures in view of these. Such measures include those
recommended by the specified standard:
- controlling the actuators via a “deadman’s button” placed near the system and within
the operator’s field of view, to ensure that people are out of the way during operation.
The button must be placed at a height of 1.5 m and operated by key if accessible to the
public; or:
- use of contact safety systems (also included in the actuators) that ensure a maximum
closing force of 400/150/25 N, measured in accordance with paragraph BB.20.107.2 of
IEC 60335-2-103; or:
- use of non-contact safety systems (lasers, light grids); or:
- use of fixed safety barriers that prevent access to moving parts.
Automated windows are deemed adequately protected if they:
- are installed at a height of >2.5 m; or:
- have a leading-edge opening of <200 mm and a closing speed of <15 mm/s; or:
- are part of a smoke and heat evacuation system for emergency use only.
In any case, moving parts of windows that could fall below 2.5 m following breakage of a
system component need to be fixed or secured in order to prevent them from suddenly
falling or collapsing: e.g. the use of safety arms on bottom-hung windows.
The device is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lacking experience and knowledge. Do
not allow children to play with the fixed controls and keep any remote-control units
out of their reach.
The actuator is destined exclusively for installation indoors. For any special
application we recommend you consult the manufacturer beforehand.
After removing packaging, check for any damage on the appliance.
Always request exclusive use of original spare parts. Failure to respect this
condition could compromise safety and invalidate the benefits contained in the
warranty for the appliance.
In the event of any problems or queries, consult your agent or contact the
manufacturer directly.

2. FORMULAS AND RECOMMENDATIONS FOR INSTALLATION
2.1. Calculation of opening / closure force
Using the formulas below, approximate calculations can be made for the force required
to open or close the window considering all the factors that determine the calculation.
Symbols used for the calculation
F (Kg) = Force for opening or closing P (Kg) = Weight of the window (mobile sash only)
C (cm) = Opening stroke (actuator stroke) H (cm) = Height of the mobile sash
For horizontal light domes or
skylights
F = 0.54 x P
(Eventual weight of snow or wind on the
cupola should be calculated separately).
For vertical windows
 TOP HUNG WINDOWS, OUTWARD OPENING (A)
 BOTTOM HUNG WINDOWS (B)
F = 0.54 x P x C : H
(Eventual load of favourable or unfavourable
wind on the sash should be calculated
separately.)
2.2. Maximum opening according to height of sash
The actuator stroke is in accordance with the height of the sash and its application.
Check that the actuator stroke does not touch the profile of the sash and that the chain
does not exert force on the window frame (measurements in mm).
ATTENTION. For safety reasons the actuator should not be assembled if dimensions are
inferior to those indicated in the table below. In the event that the height of the sash should
be lower, call on the manufacturer to check the appliance.
Mode of installation Selection of actuator stroke
110 200 300 400
Light domes, skylights or vertical top hung windows
opening outwards with frontal assembly 150 250 350 450
Top hung windows opening outwards with
horizontal assembly 150 250 350 450
Bottom hung windows (motor on frame) 250 450 600 700
Bottom hung windows (motor on sash) Consult manufacturer

3. TECHNICAL INFORMATION ABOUT FUNCTION
The chain operated actuator opens and closes windows by means of a steel chain
located inside the cover. Movement is powered by electricity which powers a gear
motor controlled by an electronic function device. Window opening can be programmed
to open at 110, 200, 300 and 400 mm (see respective chapter).
During closure the end course uses a self-regulating electronic process with power
absorption and therefore requires no regulation.
The actuator leaves the factory with factory settings of +1 cm for the return course
which allows the actuator to be assembled without electricity, with the window in closed
position after assembly is complete.
4. MANUFACTURE AND REFERENCE STANDARDS
INTENDED USE. The KATO ADV RADIO chain actuator is designed and built
to open and close awning and bottom-hung windows, dormer windows, domes
and skylights used for ventilation and climate control in rooms; any other use is
strongly discouraged, with the supplier of the entire system in any case
retaining sole liability. It can also be used in combination with the NRS1
operated rain sensors.
The actuator is manufactured in accordance with the Directives and following
Regulations listed in the attached Declaration of Incorporation and Conformity
.
Electrical connections must conform to regulations in force for the design and
set up of electrical equipment.
To ensure efficient separation from the grid, an approved type of bipolar “dead-
man” switch should be used. An omnipolar general power switch with minimum
distance of 3 mm between contacts should be installed upstream of the control
line.
The KATO ADV RADIO actuator is packed in one single carton.
Each package contains:
 Actuator with 2 metre (±5%) lead.
 Standard support brackets with distancer (A).
 Bracket for vertical assembly of the actuator (B).
 Bracket for transom window (C).
 Bracket for outward opening fixture (D).
 Template for boring.
 Instruction manual.
5. LABEL DATA AND MARKINGS
The KATO ADV RADIO actuators have CE marking and comply with the Standards
listed in the Declaration of Conformity. They also come with a Declaration of
Incorporation, due to their classification by the Machinery Directive as “partly completed
machines”. Both declarations are included in the final pages of this manual.

7. ELECTRIC POWER SUPPLY
Warning. Check that the electric power supply used corresponds to that
specified on the “technical data” label attached to the machine.
The manufacturer cannot be held liable for damage due to an application which is
incorrect or non-compliant with regulatory requirements.
The actuator is powered by a mains voltage, in alternating current, of 110-230V~ with a
frequency of 50/60 Hz.
The actuator is already equipped with a power supply cable which is 2 meters long. The
cable has two colored conductors: Phase (brown) and Neutral (sky-blue).
The connection between the line and the power supply cable of the actuator must be
protected by a magnetothermic switch between the line and actuator.
8
7.1. Selecting the cross-section of electric power supply cables
The cross-section of the electric power supply conductors must comply with current
standards on electrical systems, without prejudice to standard EN 60335 for connected
electrical devices.
8. ELECTRIC POWER SUPPLY AND SENSOR CONNECTION
8.1. Electric power supply cable
The power supply cable is already wired to the actuator. It is used for the electric
power supply of the system and should be connected to the electricity mains. The
power supply cable has two conductors: sky-blue, brown.
8.2. Cable entry to the terminal block
The cables entering on the left, in the same cable
feedthrough, are the following low-voltage cables:
 Rain sensor cable (five conductors).
 Manual open/close control cable.
After the wiring is completed (see the “Electrical
connection” chapter) and the cables and cable
feedthrough are arranged properly, it is
recommended that the cable entry be sealed with
a drop of silicone; this will prevent humidity or
water from entering.
9. ELECTRICAL CONNECTION
ELECTRIC SHOCK HAZARD.
Before beginning any work on the machine's wiring, make certain that the
electric power has been disconnected; failure to observe this rule may
compromise safety.

10. OPEN AND CLOSE COMMANDS
10.1. Remote electronic control (Radio remote control)
The PIK radio remote control is the standard-equipped device for controlling the KATO
ADV RADIO motor.
For more details on the characteristics and operation of the PIK radio remote control,
consult the instructions manual provided with the radio remote control itself.
Some functions of the radio remote control are not discussed in this manual.
THE TRANSMITTER IS NOT FACTORY-PROGRAMMED.
First follow the radio remote control instructions and then those provided below
concerning the specific operation of the machine you would like to control.
10.1.1. Saving the radio remote control
The radio remote control supplied is the PIK model, with 30 channels and a display,
which transmits at the radio frequency of 433.92 MHz; no other radio remote control
model is provided for the KATO ADV RADIO. Several actuators can be controlled with
a single radio remote control, however each channel must correspond to a KATO ADV
RADIO actuator and thus a window.
The encoding used varies for each channel, so each transmission will send a signal
that is different from all the others. It follows that the receiver must be able to recognize
the enabled transmitters, thus the transmission codes should be saved following the
procedure below:
 Equip yourself with the radio remote control, checking beforehand that it is
working, has charged batteries and is in good condition.
 Select the desired channel on the radio remote control. (Consult the instructions
manual of the PIK radio remote control).
 On the KATO ADV RADIO, briefly press (for about 1 second) the small “PRG”
button located near the terminal block. The slowly flashing LED indicates that it is
waiting to receive a valid radio code.
 Within 10 seconds, press any one of the up arrow ▲, STOP or down arrow ▼
buttons two times (once to activate the display of the radio remote control and the
second time to transmit the radio code).
 If the code is saved correctly, the LED will emit one long flash (1 sec.) to confirm;
then the LED will go out and remain at rest.
 If the code is not saved correctly - due to the memory being full, for example, or
the radio remote control being incompatible - the LED will emit a series of quick
flashes for about 1 second; then the LED will go out and remain at rest.
10
10.1.2. Erasing the radio memory
To completely erase the memory of the radio remote control on the machine, press the
“PRG” button and hold it pressed for about 20 seconds until the LED begins to flash
quickly. At this point you can release the button; the flashing continues until the memory
has been completely erased.
10.1.3. Remotely saving a radio remote control
A new radio remote control can be saved remotely – i.e., without accessing the PRG
button – only if at least one radio remote control has already been saved as described
in point 10.1.1 and you have the radio remote control which is already recognized. To
remotely save a radio remote control, follow the procedure below:
 Equip yourself with the PIK radio remote control to be saved and set it on the
desired channel (see the instructions provided with the radio remote control).
 Equip yourself with the radio remote control already saved and operating on the
KATO ADV RADIO in question.
 On the already saved radio remote control, press the following buttons in sequence:
F1, F2 and then STOP. This sequence “opens” the memory of the KATO ADV
RADIO (in the same way as pressing the PRG button).
 Within 10 seconds, press any one of the up arrow ▲, STOP or down arrow ▼
buttons of the (new) radio remote control that you want to program two times (once
to activate the display of the radio remote control and the second time to transmit
the radio code).
10.2. Control with conventional button
If necessary, due to unavailability of the radio remote control or other reason, the
controls can be connected by cable.
The control must have a clean (voltage-fee) single-pole contact, normally open, or a
deadman's button, but not a stable switch. It should be connected to the left terminal
block in the actuator, as indicated in the previous “Electrical connection” chapter.
Warning. The IN1 and IN2 controls prevail over the radio commands.
The manual control prevails over radio remote control.
10.3. Ventilation function
The commands issued by the radio remote control can include a specific function called
“VENTILATION”, which has the purpose of ventilating the room naturally for a specified
time.
To activate this function, press the following buttons in sequence: F1, F2, up arrow ▲.
The window opens and, if no other commands are given, closes again automatically
after 5 minutes. In the case in which the rain sensor, a manual command or radio
command intervened, the ventilation function stops; to restore the function, the
sequence of buttons must be pressed again.

11
11. RAIN DETECTION SENSOR
The rain sensor should be installed outside on the window frame and fixed with a screw
or weather-resistant adhesive system. The device acts only on the commands of the
chain actuator.
Warning. The command coming from the rain sensor prevails over any other
command; if a stable switch is assembled with the manual control and forced opening is
instructed, after having reached the opening stroke-end the window closes again, then
it opens again, then closes again, etc. In order to prevent this problem from arising, do
not assemble a stable control switch.
As described above in Chapter 9 (Electrical connection), a rain sensor model NRS1 can
be connected to the KATO ADV RADIO chain actuator with radio control.
The detector is capacitive sensor equipped with a heater in order to render the
detection area insensitive to the formation of dew, humidity and ice and allow it to dry
quickly after rainfall.
NRS1 is a universal sensor with relay output and voltage-free change-over contact (it
can also be used by other systems), with a heater that operates below +4 °C.
If necessary, the heater can be excluded by a dip-switch. The 5-conductor cable
provided is 5 m long, with a highly weather-resistant PVC sheath which is also non fire-
propagating and resistant to UV radiation.
12. PREDOMINANCE OF THE COMMANDS
The rain sensor intervenes when it rains regardless of the state of the commands, i.e.,
the closing command due to rain, if activated, prevails over any manual command.
13. PROGRAMMING ACTUATOR
13.1. Limit switches at opening
Four (4) positions can be selected for the limit switch of the outgoing chain.
To program, adjust the two dip-switches near left terminal board, as indicated in the
following table.

Limit switch at:
(mm)
Dip-switch n°
After the limit switches have been programmed, run a few check manoeuvres. In the
event of error, programming can be repeated to give the desired track run.
The actuator comes from production set on longer stroke (400 mm), dip-switch 1 in ON;
dip-switch 2 in ON.
13.2. Limit switches at closure
The limit switch at closure is automatic, electronically operated and cannot be
programmed. The actuator stops when the charge is absorbed when the window is
completely closed and the weather stripping is completely depressed.
12
Attention. The actuator at maximum charge, exercises a force enough to
crush fingers in the event of distraction.
After each closure or intervention of the electrical protection mechanism, the chain
moves in the opposite direction for around 1,0/1,5 mm. This is to loosen the tension of
the mechanical parts and gives correct pressure to the weather stripping.
14. ASSEMBLY
These indications are intended for the attention of technicians and specialized
personnel. Basic job and safety techniques are therefore not included.
All preparatory operations, assembly and electrical connections must be carried out by
technical and specialized personnel to guarantee best performances and good function
of the KATO ADV RADIO chain operated actuator.
First of all, please check that the following fundamental points have been satisfied:
Before installing the actuator, check that the moving parts of the window on which it
is to be installed are in perfect working condition and that they open and close
properly and are well balanced (where applicable).
Check that the electrical supply used corresponds to the indications on the
“TECHNICAL DATA” label attached to the machine and that the given temperature
range is compatible with the place of installation.
Actuator specifications must be sufficient for movement of the window without
encountering any obstacle. The limits indicated in the technical data table must not
be superseded (page 7) and the most appropriate stroke should be selected.
Calculations should be checked using the formula indicated on page 5.
Ensure that the actuator has not been damaged during transport, first visually and
then by powering in both directions.
Check that the width of the inside of the window (where the actuator is to be
assembled) is over 405 mm, otherwise the actuator should not be installed.
Check that once the actuator has been installed the distance between the fixed
part of the window frame (where the actuator is to be assembled) and the mobile
part of the window frame (where the bracket is to be fixed) is greater than or
equal to 0 mm. If this is not the case the actuator will not function correctly as the
window will not close correctly. If required, add additional thickness below the
support brackets to reset the quota.
14.1. Preparation of actuator for assembly
Before starting assembly of the actuator, prepare the following material for completion,
equipment and tools.
 For fixing onto metal window frames: M5 threaded inserts (6 pieces), M5x12 flat
headed metric screws (6 pieces).
 For fixing onto wooden window frames: self-threading screws for wood Ø4.5 (6
pieces).
 For fixing onto PVC window frames: self-threading screws for metal Ø4.8 (6 pieces).
 Equipment and tools: measuring tape, pencil, drill/screwdriver, set of drill heads for
metal, insert for screwing in, electricians pliers, screwdrivers.

16. CHECKING FOR CORRECT ASSEMBLY
 Check that the window has closed completely, even at the corners, and check there
are no obstacles caused by assembly in the wrong position.
 Check that when the window frame is closed, the chain terminal is at least a couple
of millimetres distant from the actuator body. This will ensure correct closure of the
window with correct pressure on the weather stripping. If the chain terminal is not
positioned as stated there is no guarantee the window will close correctly.
 Check that all attachments and support brackets are tightly fixed to the window
frame and that all screws are correctly tightened.
 Check that the window moves to the desired position in accordance with the limit
switch selected.
 Check that the gear motor support brackets are aligned and the four fixing screws
are firmly screwed into position.
17. EMERGENCY MANOEUVRES, MAINTENANCE AND CLEANING
Should the window have to be opened manually in the event of no electricity,
mechanical failure, or for normal maintenance or cleaning of the external surface of the
window frame, the following instructions should be followed:
1. Release the safety clip locking the chain terminal to the bracket.
2. Hold the window with one hand and pull the pin out of
the opening with the other hand (Fig. 16).
3. Manually open the window frame.
ATTENTION: DANGER – the window could fall as the
sash is no longer held in position by the chain.
4. After maintenance and/or cleaning repeat points 1 and 2
in reverse order.
