Example: Humidification
Control = 80% RH *Time of HUMID output on = 20 sec
Hysteresis = 5% RH *Time of HUMID output off = 10 sec
When humidity falls to 75% RH (80 - 5), the humidistat output starts to cycle: 20 sec. on - 10 sec. Off

F04 - Maximum setpoint allowed to the end user (thermostat)
It is to prevent that incorrect high or low temperatures be regulated.

It is the difference of temperature (hysteresis) between ON and OFF the THERM output.
F06 - Minimum delay to turn the thermostat output on
It is the minimum time that the thermostat will keep turned off, it means, the space of time between the
last stop ant the next start.

Electronic limits whose purpose is prevent that too high or too low setpoint humiditys are regulated.
F10 - Control differential (hysteresis) of the humidistat
It is the difference of humidity (hysteresis) between turn ON and turn OFF the HUMID output.
F11 - M
It is the minimum time that the HUMID output will keep turned off, it means, the space of time between
the last stop ant the next start.
F12 -
It allows to adust the time that HUMID output will keep turned on.
F13 -
It allows to adust the time that HUMID output will keep turned off.
inimum delay to turn the humidistat output on
Humidity output (time on)
Humidity output (time off)
Note: F12 and F13 functions control a cyclical program (in seconds) for the humidistat output.
This cyclical program allows that pulverized water has time to transform in relative air humidity.
To disable this function, adjust then with value “00.0”.
F14 - Auxiliary output operation mode (AUX)
Refrigeration
Heating
Dehumidification
Humidification
Intra-range alarm
Extra-range alarm
Independent cyclic timer
Cyclic timer operating only when the temperature reaches the setpoint (THERM output
deactivated)
Cyclic timer operating only when the humidity reaches the setpoint (HUMID output
deactivated)
Cyclic timer operating when the temperature or humidity reaches their setpoint
Cyclic timer operating only when the temperature and humidity reaches their setpoints.
When changing the value of this function the following parameters will be automatically adjusted with
their default values: F15, F16, F17 and setpoint for the AUX output.
F15 - Minimum setpoint allowed to the user (AUX output)
F16 - Maximum setpoint allowed to the user (AUX output)
Electronic limits whose purpose is prevent that too high or too low setpoint values are regulated.
The limits will depend on the operation mode of the output adjusted in F14.
F17 - Control differential (hysteresis) of the AUX output
It is the difference of temperature or humidity (hysteresis) between turn ON and turn OFF the AUX
output. This function depends on the operation mode of the output adjusted in F14.
F18 - Minimum delay to turn the AUX output on
It is the minimum time that the AUX output will keep turned off, it means, the space of time between the
last stop ant the next start.
Time base of AUX output timer
Allows configuring the on or off time scale for AUX output cyclic timer.
This time is valid only when AUX output will be configured in the control mode (F14 configured in 0, 1, 2
or 3).

F23 - High room temperature alarm
Temperature for activation of the high temperature alarm.
F24 - Low room humidity alarm
Humidity for activation of the low humidity alarm.
F25 - High room humidity alarm
Humidity for activation of the high humidity alarm.
F26 - Minimum delay to turn the AUX output on (alarm mode)
It is the minimum time that the AUX output will keep turned off, it means, the space of time between the
last stop ant the next start. This time is valid only when AUX output will be configured in the alarm mode
(F14 configured in 4 or 5).
F27 - Buzzer operation mode
Intra-range alarm
Extra-range alarm
F28 - Acting point of Buzzer by low temperature
It is the inferior value of temperature to the buzzer alarm act as the configured Operation Mode of Buzzer
(F27).
F29 - Acting point of Buzzer by high temperature
It is the superior value of temperature to the buzzer alarm act as the configured Operation Mode of
Buzzer (F27)
F30 - Acting point of Buzzer by low humidity
It is the inferior value of humidity to the buzzer alarm act as the configured Operation Mode of Buzzer
(F27).
Acting point of Buzzer by high humidity
F32 - Maximum time of the activated THERM output to activate the alarm
Allows configuring the maximum time the output THERM can stay activated without reaching the
setpoint before activating the audible alarm (BUZZER). To deactivate this function, just decrement the
value until the message is displayed.
F31 -
It is the superior value of humidity to the buzzer alarm act as the configured Operation Mode of Buzzer
(F27).
F33 - Maximum time of the activated HUMID output to activate the alarm
Allows configuring the maximum time the output HUMID can stay activated without reaching the
setpoint before activating the audible alarm (BUZZER). To deactivate this function, just decrement the
value until the message is displayed.
F34 - Maximum time of the activated AUX output to activate the alarm
Allows configuring the maximum time the output AUX can stay activated without reaching the setpoint
before activating the audible alarm (BUZZER). To deactivate this function, just decrement the value until
the message is displayed.
F35 -Buzzer time on
It is the time that the Buzzer will be turned on (cycle on). To turn it off the sonore alarm (Buzzer) adjust the
value “0” to this function.
F36 - Buzzer time off
It is the time that the buzzer will be turned off (cycle off). To turn the sonore alarm (Buzzer) always on,
adjust the value “0” to this function.
F37 - Inhibition time of Buzzer during electrical supply
It is the time were the alarm will kept turned off even if in alarm contitions.
It serves to inhibit the buzzer during the time while the system do not reaches the working control
temperature.
F38 - Output status in case of alarm
Status output do not change in case of alarm.
Turn off the output THERM, HUMID and AUX.
Note: The AUX output will not turn off if it is set to alarm output intra-or-extra range. In case of sensor
failure the outputs will be switched off independently of the parameter settled in that function.
F20 - AUX output (time on)
It allows to adust the time that AUX output will keep turned on when set to cyclical timer.
F21 - AUX output (time off)
It allows to adust the time that AUX output will keep turned off when set to cyclical timer.
F22 - Low room temperature alarm
Temperature for activation of the low temperature alarm.
F39 - Display mode
Alternated indication of temperature and humidity
Only indication of temperature
Only indication of humidity
F40 - Temperature display offset
It allows to compensate eventual shunting lines in the reading of temperature proceeding from the
exchange of the sensor or cable lenght alteration.
F41 - Humidity display offset
It allows to compensate eventual shunting lines in the reading of humidity proceeding from the
exchange of the sensor or cable lenght alteration.
