Parameter descriptions
SP1 = Operation order of relay 1. Specifies the ON/OFF point of relay 1. Variable
between r4 and r6.
SP2 = Operation order of relay 2. Specifies the ON/OFF point of relay 2. Variable
between r5 and r7.
r0 = Dependency between SP1 and SP2. Only for mode ONOFF1
ind = order for relay 2, SP2.
dep = order for relay 2, SP1+SP2.
r1 = Differential or hysteresis for relay 1. Temperature differential between ON/OFF
of relay 1 in ON/OFF control.
r2 = Differential or hysteresis for relay 2. Temperature differential between ON/OFF
of relay 2 in ON/OFF control.
r3 = Band differential. Temperature differential between ON/OFF of relays 1 and 2
in neutral area control. For relay 1 it is added to SP1 and for relay 2 it is subtracted
from SP1.
r4 = Lowest value for SP1.
r5 = Lowest value for SP2.
r6 = Highest value for SP1.
r7 = Highest value for SP2.
r8 = Regulation or operating mode. Selection of the operating mode.
A0 = Alarm differential. It is the temperature differential between the alarm On and
Off cycle.
A1 = Maximum alarm probe1.
A2 = Maximum alarm probe2.
Maximum alarm ON when probe 2 higher than SP2+A2
Maximum alarm OFF when probe 2 lower than SP2+A2-A0.
A3 = Minimum alarm probe1.
Minimum alarm ON when probe 1 lower than SP1-A3
Minimum alarm OFF when probe 1 higher than SP1-A3+A0.
A4 = Minimum alarm probe2.
Minimum alarm ON when probe 2 lower than SP2-A4
Minimum alarm OFF when probe 2 higher than SP2-A4+A0.
A5 = Alarm verification time. Time from the alarm event until it trips.
A6 = Alarm probe 1 selection.
AHL=Maximum and minimum alarm probe 1 enabled.
Ano=No alarms probe 1.
AH=Maximum alarm probe 1 enabled.
AL=Minimum alarm probe 1 enabled.
A7 = Alarm probe 2 selection.
AHL=Maximum and minimum alarm probe 2 enabled.
Ano=No alarms probe 2.
AH=Maximum alarm probe 2 enabled.

c0 = Minimum relay stop time. Minimum time from the disconnection of a relay until
it can be switched on again.
c1 = Operation relay 1. Selection between direct or reverse operation for relay 1.
c2 = Operation relay 2. Selection between direct or reverse operation for relay 2.
c3 = Default operation relay 1. In case of failure of probe 1:
oPn= relay 1 will remain open.
Clo= relay 1 will remain closed.
