4.161 Difference between the maximum storage
tank temperature (MSP) and the buffer
storage tank safety temperature
The temperature differential is used to define the maximum storage tank temperature
(MSP). It refers to the buffer storage tank safety temperature.
Setting range
1...50
If TPx exceeds the maximum storage tank temperature (MSP) by half the temperature
differential, priority 2 will be activated. If TPx falls below the maximum storage tank
temperature, priority 2 will be deactivated.
4.162 Hysteresis for buffer storage tank cooling
function with priority 1
The switch-off point for the buffer storage tank cooling function with priority 1 can be set
via a hysteresis.
Setting range
1...20
When the maximum buffer storage tank temperature (MSP) is reached, the buffer stor-
age tank cooling functions with priority 1 will be activated and then deactivated via the
hysteresis (also refer to graph on the previous page).
