Function is of importance only if
operating line 99 = 3
Entry --- = function deactivated
For explanation of "bivalent",
refer to operating lines 103 and
104
0 = minimal
1 = maximal
If the plant has a bypass pump
controlled via return tempera-
ture sensor B7, this setting is
inactive. In that case, the type of
limitation is always minimum
