Connection of different actuators

When connecting thermal actuators, DO4 is used for heating actuators 
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.
