ELECTRICAL CONNECTIONS
The thermostat is provided with two screw terminals for external conductors with cross-section
from 0.75 mm to 2.5 mm .
2 2
The terminals have capacity for two wires each in order to allow connection of many devices to
the same thermostat.
To connect the thermostat, follow these instruction:
• use flexible conductors suitable for the terminals provided
• loosen each terminal screw and insert the conductor, then tighten the screws. When finished,
pull the conductors gently to verify if they are tight enough
• to tighten the screws, do not exceed 0.5 Nm torque

OPERATION
The NO thermostat (Normally Open - blue) has open contact when the temperature is below
the set point value and closes with rising temperatures.
Fig.1 shows the typical operation cycle: the contact closes with rising temperature, at the
value T=T set point +4K when the rated current is 5A, or T=T set point +7K when the rated
current is > 5A.
The contact opens on descent at the value T=T set point . The set point value represents the
lower limit of the setting temperature range, the upper limit represents the differential, having a
value of +4K or +7K with respect to the set point value.
The NC thermostat (Normally Closed - red) has closed contact when the temperature is below
the set point value and opens with rising temperatures.
Fig. 2 shows the typical operation cycle: the contact opens with rising temperature, at the
value T=T set point and closes on descent at the value T=T set point -3K. The set point value
represents the upper limit of the setting temperature range, the lower limit represents the
differential, having a value of -3K with respect to the set point value.

Mounting suggestions
The thermostat must not be mounted in environments with the following characteristics:
• presence of strong vibrations or impacts
• environmental conditions not met by IP20 protection
• exposure to direct sun rays
• heat or cold sources
• openings or ventilation slots which allow the passage of hot or cold air
WARNING
This device should be installed inside enclosure. Any use different from this and any
modifications, not expressly authorized by the manufacturer, are considered inappropriate.
Eventual damages due to an inappropriate use are the full responsibility of the user.
All the service and maintenance operations must be carried out by qualified personnel only in
compliance with the respective EU power-supply guidelines.
The protective measures and the protection against contact are to be ensured by the
installation. The thermostat is a live device, reactive to the ambient temperature.
N
Before installing or following work on the thermostat or attached devices, disconnect from the
L
electrical supply.
The assembly instructions are an integral part of the product. They must be issued to everyone
who works with the product. We cannot accept any liability for damage associated with failure
to observe these instructions.
All specifications, data and drawings are subject to change without notice.
