7.5 Parameter Level “SEt PAr”
If none of the 10 parameter sets in “SEt SEL” are satisfac-
tory, an individual control parameter set can be adjusted at
this level. The values entered at “SEt PAr” become active
only if no external sensor Sn2 is attached and the value
“PAr” in “SEt SEL” is “11” (see Section 7.1).
This level can be reached by pressing the keys “Timer”, “∆”
and “∇” for at least 3 s simultaneously.
The desired setting can be reached by pressing the “∆” or
“∇” key.
To move backwards: press the “P” key for a maximum of
2 s.
To return to the operating level with display of the set and
actual values from any desired display, press the “P” key for
3 s.
Proportional band “Heating” in %.
Value with reference to 400 °C/750 °F.
Proportional band “Cooling” in %.
Value with reference to 400 °C/750 °F.
Derivative action time “Heating” in s.
Derivative action time “Cooling” in s.
Lead time “Heating” in s.
Lead time “Cooling” in s.
Neutral zone in °C/°F above the set value. In this zone, cool-
ing is not activated.
Cooling command suppression in ms. The cooling command
is suppressed during the time period set.
Note: The lead time set must always be at least 4 times
longer than the corresponding derivative action time.
