Maximum store temperature
This function is used for detecting and indicating if the adjusted maximum store
temperature has been exceeded. The controller compares the current store tem-
perature to the adjusted maximum store temperature, thus monitoring the store
loading circuits.
The maximum store temperature is considered exceeded when the temperature
measured at the store sensor exceeds the adjusted maximum store temperature by
at least 5 K. The monitoring becomes active again as soon as the store temperature
falls below the adjusted maximum store temperature.
The channels ST1, ST2 can be used for selecting the stores to be monitored. The
number of exceedances is displayed in the ST1(2)MX channels. A possible cause
for an unwanted exceedance of the maximum store temperature is a defective
valve.
