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.
Maximum temperature limit
Heating circuit without mixer
Setting of coding address "06"
Setting range0 for max. temp. from "06:01" == 40ºC
to "06:15" == 110ºC (Change per step: 5 K)
As delivered 0condition: "06:10" == 85ºC.
Heating circuit with mixer
Setting of coding address "05"
Setting range0 for max. temp. from "05:00" == 35ºC
to "05:15" == 110ºC (Change per step: 5 K)
