Function indicator
Indicates modes of operation
MAN = OFF (Automatic control)
MAN = ON (Manual control)
AUX = ON (program in reset)
PRG = ON (program running)
"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.

Indication of output states
OUT 1 (Main); OUT 2 (AL 1);
OUT 3 (AL 2); OUT 4 (HB)
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. limits
Err = PT100 third wire opened for PT100, PTC or
input values lower than min. limits
(i.e.: TC wrong connection)
SV display: Indication of setpoint
Bargraph: Percentage display for variable defined
with bArG parameter
