Wiring of various actuators
When wiring thermal actuators, DO4 is used for heating and DO5 for cooling actuators. If
the change-over function is used together with a 2-pipe installation, the actuator should be
connected to DO4 if an electric heater is not used. If an electric heater is used, the change-
over function is instead located on DO5. When wiring 3-position actuators, DO4 is used for
the increase signal and DO5 for the decrease signal, including when the change-over
function is used.
