4.5. Parameter window “Channel X”-Heating actuator
The window of “Channel X-Heating actuator” in Fig. 4.5(1) will be visible with “Heating actuator
(without controller)” in “Work mode of the channel”.
In the running mode of “Heating actuator”, it is used to control heating valve or temperature sensor
to realize the temperature constancy in the room.
There are 2 options of control mode for every output: 1 bit control and 1 byte control. Under the
1bit mode, it will receive 1 bit command by the communication object “On-off”; under the 1byte mode, it
will receive 1 byte command by the communication object “Continuous control”.
“0” means the valve is off, while “100%” is on. And 0~100% means during a cycle period, the valve
will be on for x% of the period while off for the rest time.
