Do not use solvents or jets of water to wash the appliance. The appliance should
not be submerged in water.
1.2. Notes for functioning and use
NRS1-NRS1/R
(NRS1R is different from the other because of the antenna protected by a
black sheath in the feeding cable)
is a sensor to detect rain and through the connected
cable or in case of R version by means of a 433,92 MHz radio signal, transmits the signal to
a device able to interpret it.
Use for any applications other than those indicated must be authorised by the
manufacturer after technical review of the assembly.
This product is designed to be used with the manufacturer's original products.
Use with any other products may result in damage or malfunctions.
The initial start-up of the sensor should be carried out by a skilled and qualified
person following the manufacturer's instructions.
After removing packaging, check for any damage on the appliance.
Before using the rain sensor, check that the power has the same nature, quality
and tension as those indicated on the technical data label on the appliance.
This machine is destined exclusively for the use for which it has been designed
and the manufacturer accepts no responsibility for damage incurred by improper
use.
Repairs should only be performed by qualified personnel at assistance centres
authorised by the manufacturer.
The product must be disposed of in compliance with local environmental
regulations and not as household waste.

2. TECHNICAL AND CONSTRUCTIONAL INFORMATION
NRS1
and
NRS1/R
sensors signal the rain event to an apparatus able to interpret and
command the connected devices. The sensor is insensitive to the formation of dew or
moisture after rainfall dries very quickly and being heated - below +5 °C - does not
allow the formation of ice.
The sensor is fed with a tension between 12V and 24V
.
Electrical connection must comply with the rules in force on electrical systems.
All connected devices must be manufactured according to the regulations in force and
comply with regulations issued by the European Community.

4. ID PLATE AND MARKING DATA
NRS1
and
NRS1/R
rain sensors have
marking and are destined for use in the
European Union without further requirements.
ID plate data are indicated on a polyethylene adhesive label applied on the product,
printed in black on a grey background.
5. TECHNICAL INFORMATION
NRS1
or
NRS1/R
rain sensor, to completely fulfil its task, has to be placed out in the open
fully exposed to any precipitation, possibly over the roof or in a similar position, or where
can be affected by rainfall.
Sensor can be connected to all stations or devices where signal processing is foreseen or
where a free contact signal is necessary (free from tension).
Feeding cable is 5 m long, made weather resistant, fire retardant and UV resistant.
