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.
AL=Minimum 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.
c4 =
Default operation relay 2. In case of failure of probe 1 (for all modes excepting
ON OFF2) or in case of failure of probe 2 (for mode ON OFF2):
oPn= relay 2 will remain open.
Clo= relay 2 will remain closed.
P0 =
Temperature scale selection.
P1 =
Calibration of probe 1. Offset degrees to be added to probe 1.
P2 =
Calibration of probe 2. Offset degrees to be added to probe 2.
P3 =
Decimal point. If the displayed value of the probes is desired with decimals or
not.
P4 =
Probe to be displayed. Probe always on the display. The other probe can be
seen pressing the keys SET+UP.
sd1= probe 1.
sd2= probe 2.
P5 =
Number of probes. If P5=1, there is not ON OFF2 mode. If selected, it will
operate as ONOFF1.
H0 =
Reprogramming. Parameter to reprogram the thermostat.
H1 =
Keyboard protection.
To change the sets, enter into parameter and exit again. The protection setting
is momentarily released. It switches on again 1 minute after the last time a key
was pressed.
Yes= Keyboard Protected.
No=Keyboard non protected.
H2 =
Operation of LED OUT1.
dir=
On when relay 1 is ON.
inv=
On when relay 1 is OFF.
H3 =
Operation of LED OUT2.
dir=
On when relay 2 is ON.
inv=
On when relay 2 is OFF.
H4 =
Serial communication address. Address for computer connection.
H5 =
Parameter entry code. Factory set as 0.
