proportional to the SIM value. The result is a reduction in the fluctuation of the displayed value.
2.3 INFO
MENU
. Pressing the button and releasing it immediately activates the information selection menu. From this menu you
can display the instantaneous temperatures T1, T2 and T3; the maximum (THI) and minimum (TLO) stored temperature; the total
operating time of the condenser since its last cleaning (CND) and the keypad status (LOC). The information to be displayed can be
selected sequencially, by pressing repeatedly or quickly via the buttons and to scroll through the menu. Exit from the info
menu is by pressing button or automatic after 6 seconds of not using the keypad.
In the INFO operating mode it’s also possibile to reset the recordings THI and TLO and the hour counter CND by pressing buttons
+ simultaneously while the value is displayed.
2.4 K
EYPAD LOCK. The keypad lock avoids undesired, potentially dangerous operations, which might be attempted when the
controllers is operating in a public place. In the INFO mode, through the buttons and it’s possibile to assign YES or NO to the
parameter LOC. With LOC=YES all keypad commands are inhibited. To resume normal operation of keypad, adjust setting so that
LOC=NO.
2.5 D
EFROSTING. By assigning a value grater than 0 to the parameter DDY, during defrost the indication is displayed instead of
the temperature. In this case, after defrost and for the time programmed in DDY, the display indication shows that the normal
thermostatic cycle is being resumed.
2.6 A
LARM
. An anomaly in the operation is displayed through the lighting up of an abbreviation showing its cause:
/
high/low
alarm temperature in the cabinet, door open, condenser high temperature, periodic condenser cleaning,
//
fault of
probe T1 / T2 / T3.
2.7 S
ETUP. The setup is accessed by pressing the buttons + + in succession and keeping them pressed simultaneously for 5
seconds. The available parameters appear in TABLE 2 as shown below.
3. CONFIGURATION
The controller is configured for the system to be controlled by programming the operating parameters, that is, through the setup (see par.
2.7). The instrument is dispatched with a general setup and the suitability of the parameters must therefore be checked before use. In
SETUP, press button to pass from one parameter to the next, and press button to go back. To display the value of a parameter
press , to modify it press buttons + or simultaneously. Exit from the setup is by pressing button or automatic after 30
seconds of not using the keypad. The setpoint SP (IISP) can be displayed and programmed even during normal operation of the
controller, by pressing button + or . The range will always remain within the limits SPL and SPH (IISL and IISH).
TABLE 2
CAUTION: upon changing the display scale SCL, it is ESSENTIAL to reconfigure the parameters related to the absolute (SPL, SPH, SP,
etc.) and differential (HYS, ATL, ATH, etc.) temperatures.
