Connection of different actuators
When connecting thermal actuators, DO4 is used for heating actua-
tors and DO5 for cooling actuators. If the installation is a 2-pipe
installation and the change-over function is used, the actuator should
be connected to DO4.
When connecting 3-point actuators, DO4 is used for increase signal
and DO5 for decrease signal, even when the change-over function is
used.
