Function indicator:
Indicates modes of operation
MAN = OFF (Automatic control)
MAN = ON (Manual control)
AUX = ON (program in reset)
PRG = ON (program running)
Auto / Manual selection
Only active in level 1 menu
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. 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
