EF315_r5.1(v12.22) – 03/2023 page 18
PARAMETER 33 DISPLAY OF THIRD LINE
The third line of the display is typically dedicated to the temperature (and any telephone numbers). This
parameter allows to add the displaying of the injected litres of product and / or threshold values.
Data are shown in sequence, at intervals of about 3 seconds.
• Weight 1 = add displaying of litre-counter
• Weight 2 = add displaying of thresholds
Examples: P33 = 0: shows only the temperature value
P33 = 1: alternates temperature and litre-counter
P33 = 2: alternates temperature and working thresholds
P33 = 3: alternates temperature, litre-counter and working thresholds
PARAMETER 34 TELEPHONE NUMBERS
In the event of errors or alarms (shown on the fourth line of the display), a telephone number for technical
assistance or a message can be displayed on the third line.
This parameter allows to select one of the nine telephone numbers (or messages) stored in the controller
memory and pre-set at the factory following the customer indications (Note: in the absence of customer’s
instructions, no number is stored).
The operator can set or modify these numbers (or messages) by connecting the EF315 control unit to a
PC via a serial line and using a simple communication program (e.g. Sercom or Hyperterminal). Enter the
desired values with the command “Tn=0123456789ABCDEF”, followed by “Enter”, where “n” is a number
between 1 and 9, while the 16 characters that follow the “=” are exactly those that will appear on the third
display line. Configuring P34 = 0 means excluding this function.
Warning! For a correct visualization, do not use in the message characters not allowed, such as accented
letters or with dieresis (for technical personnel: the allowed ASCII characters are those between 32d and
126d).
PARAMETER 35 AUTOSET (RESTORE FACTORY SETTINGS)
This parameter allows to restore the factory settings. The standard value to activate this function is 12
for pH/RX measurements, and 13 for pH/Chlorine version. Anyway the customer can also ask for a
different value for restoring his specific configuration. This function should be used only if the unit does
not work properly, due to wrong configuration or if a complete reset of the unit is necessary, for a following
new installation. This function also cancels all measurement offset and gain factors.
Warning! After restoring the factory settings, you must check and set again (if necessary) the
pump flow rate values and maintenance thresholds.
