Connection to a second motor (running at the speed settings of the CAIB motor) or a damper.
Information on the status of the HS and LS contactors is duplicated to permit control of a second fan or an "all-
or-none" inlet air damper.
This information is given in the form of a voltage-free contact (21-24) (breaking power 5 A max. /230 V ). This
can control:
-
A single-phase motor (directly) ( In = 5 A max.)
-
By relay: the power contactor control
-
A damper servo-motor.
The N / L1 power supply can be restored
from the switch isolator present in the
controller.
