Readout scale (see table of input specifications)
Caution: upon changing the SCL value, it is then absolutely necessary to the param-reconfigure
eters relevant to the absolute and relative temperatures (SPL, SPH, 1SP, 1HY etc..)
SPL -50°...SPH Minimum limit for 1SP setting
SPH SPL...150° Maximum limit for 1SP setting.
1SP SPL... SPH Setpoint (value to be maintained in the room).
1CM HY; PID Control mode.
With 1CM=H you select control with hysteresis: parameters 1HY Y, 1T0 and 1T1 are used.
With 1CM=PID you select a Proportional-Integral-Derivative control mode: parameters 1PB, 1IT,
1DT, 1AR, 1C will be used.T
1CH REF; HEA Refrigerating (REF) or Heating (HEA) control mode.

After output 1 has been turned it remains active for 1T1 minutes regardless of the temperature on,
value measured.
1CM=PID
1PB 0...19.9° Proportional bandwidth.
Temperature control takes place by changing the
ON time of the the closer the temperature output:
to the the less time of activation. small setpoint, A
proportional band increases the promptness of
response of the system to temperature variations,
but tends to make it less stable. A purely
proportional control stabilises the temperature
within the proportional band but does not cancel
the deviation from setpoint.
With 1PB=0 the output is always off.
1IT 0...999s Integral action time.
The steady-state error is cancelled by inserting an
integral action. The integral action determines time,
the speed the steady-state temperature with which
is but a high speed (1IT may be the achieved, low)
cause of overshoot and instability in the response.
With 1IT=0 the integral control is disabled.
1DT 0...999s Derivative action time.
Response overshoot may be reduced by inserting
a derivative Action. A high derivative action (1DT
high) makes the system very sensitive to small
temperature variations and causes instability. With
1DT=0 the derivative control is disabled.
1AR 0...100% Reset of integral action time referred to 1PB
Decreasing the parameter reduces the integral control action and consequently the 1AR zone,
overshoot (see figure on paragraph 1IT).
1CT 1...255s Cycle time.
It’s the period in the output ON time changes. The quicker the system to be controlled which
reacts to temperature the smaller the cycle time must in order to obtain higher variations, be,
temperature stability and less sensitivity to load variations.

Press button ■ to display value.
To exit from the menu, press button ■ or wait for 10 seconds.
Reset of THI, TLO recordings
With button ■ or select the data to be reset.
Display the value with button ■.
While keeping button ■ pressed, use button .
CHANNEL 1 SETPOINT (display and modification of desired temperature value)
Press and release button ■ : the ED blinL L1 ks, the display shows 1 P for 1 second and then the setpoint associated value.S
Press buttons ■ or to set the desired value (adjustment is within the minimum SPL and maximum SPH limit).
To store the new value press button ■ , or wait for 10 seconds.
To go back to normal mode without saving the new value, press ■.
CHANNEL 2 SETPOINT
With the auxiliary output set as thermostat control ( ■ =THR),OAU it’s possible to modify setpoint 2 during the normal operation
of the controller.
Press and release button ■ : LED L2 blinks, shows 2S the the display P for 1 second if setpoint 2 is an absolute threshold
( alternatively the display 2DF2SM=ABS), shows , =REL), if setpoint 2 is a threshold relative to setpoint 1 (2SM then the value
associated to the parameter appears.
Press buttons ■ or to set the desired value.
To store the new value press button ■ or wait for 10 seconds.
To go back to normal mode without saving the new value, press ■.
STAND-BY
Button , when pressed for 3 seconds, allows the controller to be put on a standby or output control to be resumed (with SB=YES only).
KEYPAD LOCK
The keypad lock avoids potentially dangerous might be attempted the controllers is operating undesired, operations, which when
in a public place. In the INFO set parameter to inhibit all functions of the buttons. To resume normal operation menu, LOC=YES
of keypad, adjust setting so that LOC=NO.
CONTROLLER AUTOTUNING IN PID MODE
Before starting
In the setup mode (see set =PID; make sure that matches the desired operation mode configuration parameters): 1CM 1CH
(1CH 1CH=REF for refrigerating control, =HEA for heating control); then adjust setpoint 1SP at the desired value.
Start autotuning
During normal keep buttons operation, + pressed for seconds. 1CT blinks on the display. With + or set the cycle 3
time in order to the dynamic of the process to be controlled. To abort the autotuning press define function, ; to start autotuning
press + or wait for 30 seconds.
During autotuning
During the entire autotuning the display alternates the actual temperature measured. In case of phase, TUN with power failure,
when power resumed, phase, is after the initial autotest the controller resumes the autotuning function. To abort the autotuning,
without parameters, modifying the previous control keep button pressed for seconds. the autotuning has taken place 3 After
successfully, the controller updates the control parameters and start to control.
Errors
If the autotuning function failed, the display shows an error code:
E1 timeout1 the controller could not bring the temperature the proportional band. Increase error: within■ 1SP in case of heating
control, vice versa, decrease 1SP in case of refrigerating control and re-start the process.
E2 timeout2 the autotuning has not ended the maximum time cycle Re-start the autotuning error: within allowed (1000 times).■

E3 overrange: was malfunction, temperature check that the error not caused by a probe then decrease ■1SP in case of heating
control, vice versa increase 1SP in case of refrigerating control and then re-start the process.
To eliminate the error indication and return to the normal mode, press button ■.
