Description
Controller operating mode (1 = heating, 2 = cooling, 3 =
heating & cooling) (see below)
Parameterisable reaction to errors (see below)
TRUE = external parameter set, FALSE = internal
parameter set (from tuning)
Masks out the alarms (see below)
Controller's sampling time. In the course of the sampling
time the controller re-calculates the control value.
Task cycle time. The FB is called with this time interval.
Selects how tuning should be done (see below)
Waiting time (stabilisation of process) until step for tuning
is switched on.
percent of setpoint when controller stops tuning and waits
for switching to closed loop control
Control value for tuning step in cooling mode.
Control value for stabilizise process before cooling tuning
starts.
Scaling factor: if only heating tuning was done cooling
parameters are heating parameter*scaling factor
Minimum value of the control variable.
Maximum value of the control variable.
FALSE = no soft start, TRUE = soft start
FALSE = no ramping, TRUE = ramping
Setpoint while soft start phase
Waiting time in soft start phase
Enables ramping in soft start phase
Rate of rise (of ramp) during the start-up phase.
Rate of fall (of ramp) during the start-up phase.
Rate of rise (of ramp).
Rate of fall (of ramp).
Time constant of the actual value filter (first order P-T1
filter)
The actual value filter is actuated if TRUE.
TRUE = Deadband on, FALSE = Deadband off
Size of deadband in °C
Minimum value of the control variable.
Maximum value of the control variable.
Control value in manual operation.
Control value in case of error (parameterisable).
