Function indicators
Indicates modes of operation
MAN = OFF (Automatic control)
MAN = ON (Manual control)
AUX = OFF (IN1 = OFF - local Setpoint 1)
AUX = ON (IN1 = ON - local Setpoint 2)
REM = OFF (local Setpoint)
REM = ON (remote Setpoint)
"Raise" and "Lower" key
Press to increment (decrement) any numerical
parameter ••
Increment (decrement) speed is proportional to time
key stays pressed ••
The operation is not cyclic: once the maximum
(minimum) value of a field is reached, the value will
not change even if the key remains pressed.

PV Display: Indication of process variable
Error Indication: LO, HI, Sbr, Err
LO= the value of process variable is < di LO_S
HI= the value of process variable is > di HI_S
Sbr= faulty sensor or input values higher than max.

Err= PT100 third wire opened for PT100, PTC or
input values lower than min. limits
