Description of parameters
• Inside the tables, the labels are presented in the same order as they appear in the
various menus of the instrument.
[REG] regulation menu
Notes:
(1) For values LO1/LO2 and HI1/HI2, see the display menu [DSP]
(2) Parameter active only if the operating mode permits
[OUT] output menu
Notes:
(3) This parameter enables the handling of the times defined by DON, TOF and TON for
each output channel, in the following ways:
0
timing not enabled for either relay output
1
timing enabled for relay 1 output only
2
timing enabled for relay 2 output only
3
timing enabled for relay 1 and 2 outputs
(4) this parameter limits the number of start-ups per hour for the driver connected to
the instrument (this parameter is frequently used for compressors, for example)
(5) the minimum time for which the output should remain ON
(6) timing enabled for relay 1 output only OFF

(7) the delay time for the driving of the outputs from the instant of instrument reset
(8) the period that can be set for PWM regulation. This item is displayed only if the
operating mode selected is PRO=5 (see system menu).
[ING] outside input menu
Notes:
(9) The values that can be set are:
0
Not active
1
Outside alarm (with contact open) with delay time “DID” and automatic
reset at the end of the alarm. The output status becomes “SUI”
2
Outside alarm (with contact open) with manual reset
3
The input operates as a switch: instrument on with contact closed and off
with contact open
4
The input operates as a switch for the display of the two probes S0 and S1
(contact open-probe S0, contact closed-probe S1)
The digital input function is excluded when one of the following
operating modes is selected inside the system menu [SYS]:
mode=6, mode=7 and mode=8
(10) This is the delay after which the instrument responds to a signal from the digital
input
(11) When the digital input is active and a time period “DID” has lapsed,
the outputs take on the following states:
0
Both relays OFF
1
Relay 1 ON and relay 2 OFF
2
Relay 1 OFF and relay 2 ON
3
Both relays ON
(12) This is the variation of the “Set” in degrees when the instrument switches
to night operation
