Room Temperature Controller
The chart shows the relevant communication object for the temperature value:
Number Name
0 Actual temperature value
Table 4: Communication object – Temperature value
Send min/max value
This function activates the sending and saving of the min/max values. When the function is activated
by "Send enable", three communication objects will be shown. Two objects for the Min and the Max
value and one for the reset of the min/max values.
The chart shows the relevant communication objects for this parameter:
Number Name
21 Max memory value
22 Min memory value
23 Min/Max memory reset
Table 5: Communication objects – Min/Max values
Internal/external sensor
This setting sets the balance between an internal and an external sensor. The setting 100% intern
deactivates any external sensor. By choosing any other setting, an external sensor will be activated.
So, also communication objects for the external are shown. A balance of 100% extern deactivates the
internal sensor and the temperature controller will only note values of the external sensor.
The communication objects for an activated external sensor are shown at the chart:
Number Name
5 External sensor
28 Error external sensor
