Warnings
• If the equipment is used without adhering to the manufacturer's instructions, the device safety requirements could be
compromised. Only probes supplied by Danfoss must be used for the unit to operate correctly.
• From -40 – +20 °C, if the NTC probe is extended to 1000 m with at least 0.5 mm
• It should be installed in a place protected from vibrations, water and corrosive gases, where the ambient temperature does not
exceed the value indicated in the technical data.
• For the reading to be correct, the probe should be used in a place without heat in uences apart from the temperature you want to
measure or control.
• IP65 protection degree is only valid with the protection cover closed.
• IP65 protection degree is only valid if the cables enter the device using a tube for electric conductions + gland with IP65 or above.
The size of the glands should be suitable for the diameter of the tube used.
• Do not spray the unit directly with high-pressure hoses, as this could cause damage.
IMPORTANT:
• Before starting the installation, you must take the advice of local regulations in force.
• The AUXILIARY relays are programmable, and their operation depends on the con guration.
• The function of the digital inputs depends on the con guration.
• The recommended currents and powers are the maximum working currents and powers.
Wiring
Always disconnect the power supply to do the wiring.
The probes and their cables should NEVER be installed in a conduit together with power, control or power supply cables.
For disconnection, the power supply circuit must be equipped with at least a 2 A, 230 V switch, located near the device. The power
supply cable shall be of the H05VV-F or NYM 1x16/3 type. The cross-section to be used will depend on the local regulations in force,
but must never be less than 1.5 mm
Cables for relay or contactor outputs must have a cross-section of 2.5 mm
and must be installed with as little bending as possible.
The 120/230 V~ wiring area must be kept clear of any other external element.
The wiring to be undertaken depends on the option selected in the initial con guration wizard. Use the appropriate diagram
based on the option selected. Check the available options on the diagrams included in the controller's packaging. Wizard refers
to a built in tool to guide the user through the set up process.
Maintenance
• Clean the surface of the unit with a soft cloth, water and soap.
• Do not use abrasive detergents, petrol, alcohol or solvents, as this might damage the unit.
