Warning:
Use shielded and twisted signal cables and connect shield to ground on device side. Use
correct compensation cables for T/C sensors. Connect T/C cable directly to the device
connectors. Keep all signal cables away from contactors, devices/cables emitting electrical

Keep device away from contactors, devices/cables emitting electrical noise, power cables.
Take precautions agains environmental conditions like humidity, vibration, pollution and
high/low temperature during installation.
Use fuse (F250mA 250VAC) on mains/supply input of the device. Use appropriate cables
for mains connections. Apply safety regulations during installation.

•Before starting Auto-tune, adjust H.SET.
•Auto-tune does not start in “cooling” mode.
•Process value may exceed H.Set during auto-tuning.
•After auto-tuning, control form automatically switches
to PID mode.
•Auto-tuning is stopped (interrupted) any time by
pressing any key. In this case, the parameters before
auto-tuning is valid.
•Auto-tuning may not always determine the best values
for your process.

PID Parameters:
P,PI,PD,PID is active when “H.Hys” is set to 0 (only for heating; h-C is set to ”HEAt”)
PbC: Proportional band in oC
Ct: Control period for PID control. Prefer 4-10 sec.
Ti: Integral time; Set in minutes. Determines how fast controller reacts to compansate the
offset between SET point and the process value. If set to 0, integral part is OFF. If set too
low, process value may oscillate.
Td: Derivative time; Set in minutes. If set to 0, derivative part is OFF. Determines how
sensitive the controller is to changes of the offset between SET point and the process value.
If set too high, process value may oscillate or overshoot.
