5. Cost programming (System constants)
Press + / - and COMP together for more than one second; the message COSt will be displayed.
Press AGIT to move ahead until the desired variable (see table below).
The display will show the pre set value of the selected variable alternate to the messsage.
Press + or - to set a new value; press AGIT to confirm. Next variable will be displayed alternate to the pre set value.
Operate as described to proceed the program. Press AGIT for more than two seconds at any time to escape and return
to the Standard Mode.
Message Value Description Notes
diF.C 1.0° °C Compressor 1 differential A
rEL.A 2.0° °C temperature alarm for °C SET B
t.ALL 0' Delay minutes from temp. alarm from ON COMPR. B
rEL.2 0.0° °C compressor 2 set referred to t.Set. A
diF.2 1.0° °C Compressor 2 differential A
t.Con 10” Delay seconds compressor 2 startup A
t.on 0' Working minutes for AGITATORS CYCLE (0=ecxluded) C
t.oF 0' Working minutes for AGITATORS CYCLE (0=ecxluded) C
rit.C 10" Compressor start delay time seconds D
P.on =1 Pump state at ON CYCLE E
Ad.tE 0,0° °C correction of probe temperature F
Notes:
A - (see Diagram 11.3)
B - The set value rEl.A (ex. +2°C) is added to the value t.SEt (ex. +4°C). The system will go into warning cond ition if
the resulting +6°C ( rEl.A+t.SEt ) are not reached after time t.ALL. Message ALL.tE flashes on the display.
Alarm is excluded with t.ALL = 0 '.
C - Agitators start and stop with compressor. At compressor stop comes in force the cyclic mode with on and off.
With setting t.on=0' or t.oF=0' the cyclic time for the agitator is not inserted.
D - At “on” start (if required) the compressor starts with the set delay time. During this time the diod COMP
flashes.
E - P.on = 1 : with CICLO OFF everything is switched off, also the pumps (if on). At new start (CICLO ON) pumps
remain off (they can obviously be switched on with button POMPA 1 and POMPA 2 or from external contact).
P.on = 2 : with CICLO OFF everything is switched off, also the pumps (if on).At new start (CICLO ON) pumps go
back to the mode previous to the switch off (CICLO OFF).
F - It is possible to adjust the temperature read from the sensor inserting a positive ( button + ) or a negative (
button - ) correction.
6. Bootstrap or data re-setting
This processor is pre-programmed (see paragraph 1.0).
Proceed as follows to go back at any moment to the defaults programmed data:
- press together + / - and AGIT for more than one second. The display shows the message boot (then
release button AGIT);
- after a while the appliance will go back to standard run mode with the following default data set at factory:
t.SEt = 2.0°C
mode StoP
dAY 1 = -on- = 8.00 -oFF- = 18.0
cycle -Si-
The user will have to set again eventual other values if different from the default.
To help the user we write hereafter a table with default values on column A and empty space for eventual changes in
column B.
