When Digital Temperature Controllers are

connected, set points and RUN/STOP

commands can be sent from the Digital

Temperature Controller that is set as the

master to the Digital Temperature

Controllers that are set as slaves.

Slope and offsets can be set for the set point.

Number of connected Digital Temperature

Controllers: 32 max. (including master)

When Digital Temperature Controllers are

connected, the parameters can be copied

from the Digital Temperature Controller that is

set as the master to the Digital Temperature

Controllers that are set as slaves.
