4.4.4 Controller parameter
This menu only appears for "Use unit as: controller"!
The output of the control variable is defined with the setting of the control value. Depending on this
setting, the other setting options are displayed.
The following table shows the setting options for this parameter:
ETS-Text
Dynamic range
[Default value]
Comment
Control value
▪
PI control continuous
▪
PI control switching (PWM)
▪
2-step control (switching)
Defines the control after which the
control value is output.
Table 60: Settings
–
Control value (Type of controller)
The temperature controller has three different types of controllers that determine the control value.
The further configuration options depend on the controller type used.
The following table shows the available communication objects:
Number Name/Function
Length Usage
10
Control value Heating
–
Send control value
1 Byte
1 Bit
Controlling the actuator for the heating process.
DPT depending on the set parameter.
10
Control value Heating/Cooling
–
Send control value
1 Byte
1 Bit
Controlling the actuator for the heating and
cooling process
11
Control value Cooling
–
Send control value
1 Byte
1 Bit
Controlling the actuator for the cooling process.
DPT depending on the set parameter.
Table 61: Communication objects
–
Control value
Depending on the controller type set, the control value controls the heating and/or cooling process.
If the control value is selected as a continuous PI control, the communication object for the control
value is a 1 byte object, as the control value can assume several states. If the control value is
selected as 2-point control or as PWM control, the communication object is a 1-bit object, as the
control value can only assume 2 states (0; 1).
