76 Integral Time 1
i.t. 1
Integral time for process 1 P.I.D. regulation (process inertia duration).
0.0...2000.0 sec. (0.0 = integral disabled), Default 0.0
77 Derivative Time 1
d.t. 1
Derivative time for process 1 P.I.D. regulation (Normally ¼ of integral time).
0.0...1000.0 sec. (0.0 = derivative disabled), Default 0
78 Dead Band 1
d.b. 1
Dead band of process 1 P.I.D..
0...10000 [digit
79 Proportional Band Centered 1
p.b.c. 1
Defines if the proportional band 1 must be centered or not on the setpoint. In double loop
functioning (heating/cooling), always disabled.
Disabled. Band under (heating) or over (cooling)(Default)
diSab.
Centered band
Enab.
80 Off Over Setpoint 1
o.o.s. 1
In P.I.D. enables the command output 1 switching off, when a certain threshold is exceeded
(setpoint + Par.81)
Disabled (Default)
diSab.
Enabled
Enab.
81 Off Deviation Threshold 1
o.d.t. 1
Selects deviation from command setpoint 1, to calculate the intervention threshold of "Off Over
Setpoint 1" function.
-9999...+9999 [digit
82 Cycle Time 1
c.t. 1
Cycle time for P.I.D. regulation of process 1 (for P.I.D. on remote control switch 15 s; for PID on SSR
2s). For valve refer to parameter 47

parameter AL.1 .. AL.6.
Air (Default)
Air
Oil
oiL
Water
Water
84 Proportional Band Multiplier 1
P.b.M. 1
Proportional band multiplier for heating / cooling P.I.D. for process 1. Proportional band for
cooling action is given by parameter P.B. 1 multiplied for this value
1.00...5.00. Default: 1.00
85 Overlap / Dead Band 1
o.d.b. 1
Dead band combination for heating / cooling P.I.D. (double action) for process 1.
