5.1.3.1. Coldroom temperature regulation
The fields of the temperature values for which the Blocksystem series FS can operate are reported in
Table 5.
Table 5 – Temperature value fields.
High temperature HBP
(Not planned for SV)
Medium temperature MBP
Low temperature LBP
It is possible to access the regulation set point of the temperature in a direct manner to display or change the value. In relation to this,
implement the following procedure:
1. Press and release SETPOINT: the display shows "SET" (if there are alarms ongoing the procedure is slightly different; see
Paragraph 5.1.4)
Press SETPOINT: in this way the green SET led switches on and the display shows the SETPOINT value.
2.
3. Press UP and DOWN to set the new value.
4. Press SETPOINT or ON/OFF (or wait for the 5 second timeout) to confirm the value; in this way the SET led switches off and the
display shows "SET".
5. Press ON/OFF (or wait for the 5 second timeout) to return to normal view.
5.1.3.2. Change level 1 parameters
To change the parameters corresponding to level 1, use the following procedure:
1. press SET for 5 seconds until the displays shows "reg" (regulation parameters);
press UP and DOWN to display the desired menu on the display;
2.
3. press SET to access the menu; in this way the code appears of the first parameter of the menu selected;
4. press UP and DOWN to display the desired parameter;
5. press SET to display the parameter value;
6. press UP and DOWN to set the desired value;
7. press SET to confirm the value and return to the parameters list; or press ON/OFF to confirm the value and return to menu list;
8. to pass to the parameters list to the menu list press ON/OFF;
9. to exit the change parameters procedure press ON/OFF again.
If you don't press one of the keys for more than 15 seconds, the possible value display is stored in the relative parameter and you are
forced to exit the change parameters procedure.
5.1.4. Machine status view
To view the machine status, use the following procedure:
press and release SET: the display will show "SEt" or "AAL" if there are alarms in progress;
1.
2. press UP and DOWN to view the relevant status. The statuses could be:
AAL alarms ongoing (if present)

SEt setpoint

Pb1 coldroom temperature probe value

Pb2 evaporator temperature probe value

Pb3 probe value 3 (if present)

Out relay outputs status

InP digital inputs status

3. press SET to display the value;
4. in the case of alarms status, outputs status, inputs status, press UP and DOWN to scroll respectively the ongoing alarms, the
outputs and the inputs;
5. press SET or ON/OFF (or wait for the 5 second timeout) to return to the list of statuses;
6. press ON/OFF (or wait for the 5 second timeout) to return to normal view.
