Return diversion

4.154 Return diversion temperature differential ON
(ZuFu1)
Defines the temperature differential required for activating auxiliary function "Return di-
version" (ZuFu1).
Setting range
Line 481...40
The controller compares the temperature acquired with sensor B73 with the tempera-
ture of the sensor on operating line 483 and activates the auxiliary function as soon as
the required temperature differential is reached.
If the temperature differential is smaller, the auxiliary function will not be activated.
The effect changeover depends on the mode of operation selected on operating line
482.
For a description of the auxiliary function and a graph, refer to operating lines 140 and
141.
4.155 Return diversion temperature differential OFF
(ZuFu1)
Defines the temperature differential required for deactivating auxiliary function "Return
diversion" (ZuFu 1).
Setting range
0...line 480
The controller compares the temperature acquired with sensor B73 with the tempera-
ture of the sensor on operating line 483 and deactivates the auxiliary function as soon
as the temperature differential drops below the value set here. If the temperature differ-
ential is larger, the auxiliary function remains activated.
The effect changeover depends on the mode of operation selected on operating line
482.
For a description of the auxiliary function and a graph, refer to operating lines 140 and
141.
