Connect the circulation pump and valve actuator for chilled
water according to the table. If the pump motor does not have
an integrated alarm unit, the motor protection can be used
to receive an alarm signal. Connect a 3-phase pump directly to
the contactor. Connect a 1-phase pump via a quick-t connector
an alarm signal. Connect a 3-phase pump directly to the
contactor. Connect a 1-phase pump via a quick-t con-
