5.7.12 Dynamic determination of the tc setpoint
Only UA 410 E AC and only controller type UK 100 E or KR 160 E
The t
c
setpoint can be dynamically calculated depending on the difference of t
c
actual value from t
0
. This function
can be used by using a local pressure transmitter (AIN2, terminals 11/14) or a tc actual value transmitted from a
pack controller via the CAN bus.
The following parameters (menu 6-2-6) must be observed:
Set parameter "Fkt. AIN2" to tc TK .
Parametrise analogue input AIN2 and/or parameter Verb. tc TK
Set tcZ2-Ramp/m to values not equal to "--"
Then the function can be set using the parameters "tcZ2-Max", "tcZ2-Min" and "tcZ2-toZ1Df". The dynamically
determined tc setpoint can never be greater than “tcZ2-Max” and never smaller than “tcZ2-Min”. The parameter
“tcZ2-Ramp/m” specifies the maximum speed at which the dynamically determined tc setpoint can change in
Kelvin per minute.
