4 Working with the master
Process sequence for hot water (area = hot)
At the set start-up time the first valve regulates its flow to the set temperature , in the
shown example to 57 °C.
Then the second valve regulates its flow, followed by the other valves, and finally the pro-
cess is repeated until all valves reach the set
temperature or the 4 hours have passed.
If the temperature lower limit (here: 50 °C) is fallen below, an error message appears
and an entry is made in the error log.
If the temperature upper limit (here: 90 °C) is exceeded, an error message appears
and an entry is made in the error protocol. These two limits must be defined mean-
ingfully, since they form the basis for an evaluation of the
protocols .
If the checkmark at Thermal disinfection (TD) is set, the parameters shown below it
are displayed and active. Thermal disinfection process see Thermal disinfection .
Process sequence for cold water (area = cold)
At the set start-up time the first valve regulates its flow to the set temperature , in the
shown example to 15 °C.
Then the second valve regulates its flow, followed by the other valves, and finally the pro-
cess is repeated until the 4 hours have passed.
If the temperature lower limit (here: 2 °C) is fallen below, an error message appears
and an entry is made in the error log.
If the temperature upper limit (here: 25 °C) is exceeded, an error message appears
and an entry is made in the error protocol. These two limits must be defined mean-
ingfully, since they form the basis for an evaluation of the
protocols .
Thermal disinfection (TD) is not necessary for cold water.
