ELECTRICAL CONNECTIONS
The dual thermostat is provided with four screw terminals for external conductors
with cross-section from 0.75 mm
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 instructions:
• 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 dual thermostat (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 dual thermostat (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 NO
{
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. Before installing
or following work on the thermostat or attached devices, disconnect from the electrical supply.
