Over shoot reduction: All options other than “OFF” may help to reduce over
shoot more but also may increase instability around SET point. For this reason;
First try “OFF” option then 10.0->5.0->3.0->1.0->0.2 options if needed.
Options 1.0 and 0.2 are most sensitive and may result more instability around
SET point among other options. With this parameter, over shoot is not allowed
more than; OFF: not limited, 10.0: 10 , 5.0: 5 , 3.0: 3 , 1.0: 1 , 0.2: 0.2 degrees
(over SET point).

PID PARAMETERS
- P, PI, PD, PID is active when “H.hys” is set to 0.
- 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 compensate 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.
CLAEANING
Do not use any solvents (alcohol, thinners, benzine, acid, etc.) or corrosive substances to clean the device. Use only a dry
and clean non-abrasive cloth. Before cleaning, disconnect the power supply and mains connections.
