Circuit Setting range
II OFF / 1 ... 30 K
M3 is closed if the actual flow temperature drops too much below
the desired flow temperature. The max. deviation is set here.
This condition must last longer than the time intervalset in line 7.
See also line 6.
OFF: M3 is not active.
1 ... 30:
M3 close is active if the actual temperature
falls below the acceptable deviation.
6 Acceptable temperature deviation above the desired
flow temperature
Circuit Setting range
II
M3 is closed if the actual flow temperature rises too much above
the desired flow temperature. The max. deviation is set here.
This condition must last longer than the set time interval in line 7.
This function can only be activated if the value in line 5 is set to
1 ... 30 K.
1 ... 30: The M3 close function is active if the
actual temperature rises above the
acceptable deviation.

If a condition from either line 5 or 6 is present for a longer time
than the time interval set here, M3 closes.
