Description
Fixed set buffer temperature for coolant buffer
cylinder ("Fix")
If the differential between the actual and set buf-
fer temperature is greater than this start differen-
tial, a demand is triggered.
If the differential between the actual and set buf-
fer temperature is smaller than this stop differen-
tial, the demand ends.

Description
Fixed set buffer temperature for heating water
buffer cylinder ("Fix")
Set value for parallel operation of coolant buffer
cylinder AC and heating water buffer cylinder
If the differential between the actual and set buf-
fer temperature is greater than this start differen-
tial, a demand is triggered.
If the differential between the actual and set buf-
fer temperature is smaller than this stop differen-
tial, the demand ends.
