1) On mixed heating systems (application example 2) the room temperature setting applies for the constant and
variable temperature circuit.
2) On separate heating systems (application example 3) the room temperature setting on the heating circuit
module HKM applies for the CT heating circuit. The room and hot-water temperature setting on the room
control module RRG applies for the VT heating circuit.
