Differential temperature
Setting of coding address "07"
Differential temperature setting range from "07:00" = 6 K
to "07:15" = 36 K (Change per step: 2 K)
As delivered condition: "07:01" = 8 K.
Note: If Vitotronic 050 is connected, the set differential
temperatures add up (as delivered condition
respectively 8 K). Therefore set the differential
temperature on Vitotronic 050 appropriately lower.
