IMPORTANT:
in order to avoid that
SC6D malfunction
causes damage to
animal's health we
suggest to install an
indipendent minimum-
maximum alarm system
(See our depliantl).

INSTALLATION
How to connect the auxiliary contacts:
Connect 41-42......43-44 terminals on the terminals block (contacts up to 2AMP.AC1)
to the loads as shows in the diagram.
Protect contacts with a 2AMP.F fuses.
How to connect temperature probe.
Connect the sensor provided as shown in the diagram: for remote connections use a
standard 0,5-square millimetre two-pole wire, taking great care over the connections,
by insulating and sealing carefully the joints.
In case of strong radio-interference insert a ferrite sleeve in the cable near regulator.
How to connect the power line.
Connect power line on L-N terminals, connect earth on PE terminal.
Protect against electric shocks by a line differential breaker.
SC6D istallation.
Place installation in a clean and dry site.
Connectelectricwiressuchasshownindiagram;useIP55cross-cablefornotdegrade

Inordertoavoiddamagetoregulatorduringdrillingispossibletoremovebasedprinted
circuit (fixed by 4 screws).
Fuse replacement.
Switch off line switch and replace with a 8A FF 6.3x32mm ceramic fuse.
Before switching on power line verify cause of over current.
Minimum speed setting.
To allineate setting of minimum speed to effective ventilator's minimum speed
(VENT key SP._ _ function) plug-off CNA connector on relay's circuit and adjust
MINIMUM trimmer to get minimum required speed.
Press HEAT (key lamp flashes) :
this message will be displayed instead of the
°C Heat temperature value.
Press +or -to modify, press HEAT to exit.
The light situated at the bottom of display shows the state of the controller.
