Predefined control parameters and recommend control types for cooling systems
If the "Type of heating" or "Type of cooling" parameters are set to "Via control para-
meters", it is possible to adjust the control parameters manually. The feedback con-
trol may be considerably influenced by presetting the proportional range for heating
or for cooling (P component) and the reset time for heating or for cooling (I compon-
ent).
Even small adjustments of the control parameters will lead to noticeable differ-
ent control behaviour.
The adaptation should start with the control parameter setting for the corres-
ponding heating or cooling system according to the specified fixed values
mentioned in the above tables.
