Function
01
2
Configuration of final control elements according to the type of heating system. Valve V1 always controls
only one circuit, whereas valve V2 can control one or two heating circuits and/or a domestic-hot-water
circuit. Valve V2 is also responsible for pre-control when 2 valves are connected in series.
–1 =
No final control element available
+0 =
Only final control element V1 available for controlling the first heating circuit (HK 1)
+1 =
Only final control element V2 available. This valve can control the heating circuits (HK 1 & HK 2)
as well as the domestic-hot-water circuit.
+2 =
Final control elements V1 and V2 are available and hydraulically connected in parallel.
V1 controls only heating circuit 1. V2 covers the remaining functions including domestic-
hot-water regulation and/or control of a second heating circuit.
+3 =
Final control elements V1 and V2 are available and hydraulically connected in series (separated
by a heat exchanger). V1 is the secondary valve and controls only heating circuit 1. V2 is the
primary valve and covers pre-control and can also control heating circuit 2 and/or domestic-
hot-water supply.
+4 =
Final control elements V1 and V2 are available and hydraulically connected in series (separated
by a heat exchanger). V1 is the secondary valve and controls only domestic-hot-water supply.
V2 is the primary valve and can also control the heating circuits
