Parameter

Name

Type

Description

Setpoint

LREAL

The temperature setpoint of the zone.

StandbySetpoint

LREAL

This value is used as the temperature setpoint by the zone in standby.

Setpoints

ARRAY OF LREAL

Additional setpoints can be specified here, which can be easily switched over via an index. The number of the index is to be specified in TempCtrl.SelectSetpoint.

Threshold_PP

LREAL

The outer positive tolerance limit.

Threshold_P

LREAL

The inner positive tolerance limit.

Threshold_M

LREAL

The inner negative tolerance limit.

Threshold_MM

LREAL

The outer negative tolerance limit.

Openloop_Output

LREAL

Control value output if no actual temperature is available.

SaveDelay

DINT

Memory delay in µs. After a time written to this variable by the application, the saving of the actual values is triggered. (If the value is zero, the system is saved; if it is -1, the system is at rest; if the value is greater than zero, the system is saved after the time has elapsed)

Update

BOOL

With a TRUE the user interface signals here that it has changed values in this structure. The framework will check these values, adjust them if necessary and adopt them.

bLoadParams

BOOL

This flag triggers the saving of the parameters.

bSavingParams

BOOL

Signals to the application that data are being saved.
