ALARM ALARM
(*) AL.tY = bn.i is same as bnd except that if AL.tY = bn.i, ALARM is never ON before PV is in band.
(**) AL.tY = -bn.i is always same as -bnd.

ON-OFF is active when
“H.Hys”
is other then 0

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 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
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.
