PW 6xx7
If the programmer selects “user-defined” and programs water inlet valves 1 to 4,
then generally optimal water intake (without additional heating) will not occur. If
the programmer selects only hot-water valves and/or forces a rise above the
target temperature, the control reacts with a cold-water intake via the following
alternative valves:
Actual temperature > Target temperature
W1 Substituted with K1
W2 Substituted with K2
WD Substituted with KD
Table 100-29: If the target temperature is exceeded, the control automatically opens
cold-water valves instead of hot-water valves.
If valves are programmed for the water intake that do not exist in the machine,
the control substitutes these for others as shown in the following table:
Programmed valve Substitute valve activated by control
K1 KD
K2 KD
K3 KD
K4 KD
K6 KD
KD K1
KH KD
W1 WD
W2 WD
WD W1
Table 100-30: List of Substitute Valves if Programmed Valve is Not Available
After the target level has been reached, valves K3 and K4 should not be
activated during any additional intake. If the programmer has selected only
these valves, the control will operate substitutes as shown in the following
table:
Programmed valve - Water intake 1 Substitute valve activated by control during
additional intake
K3 KD
K4 KD
