With the arrows it’s possible to change the value within the LS and US
parameters value.
By pressing SET it is possible to confirm the value that will blink for
about 2 sec.
In any case, it is possible to wait for about 10 sec to exit. In order to show the air temperature set is sufficient to
press and release the SET button, the value is displayed for about 60 sec.KEY COMBINATIONS
8. HOW TO PROGRAM THE PARAMETERS (PR1 AND PR2)
The device provide 2 programming levels: Pr1 with direct access and Pr2 protected with a password (intended
for experts).
Press and hold for about 3 sec to have access to the first
programming level (Pr1).
Select the parameter or submenu using the arrows.
Use the arrows to modify the value.
Press SET key: the value will blink for 3 sec, and then the display
will show the next parameter.
Instantaneous exit from the programming mode, otherwise wait for
about 10 sec (without press any button).
8.1 HOW TO HAVE ACCESS TO “PR2”
To enter Pr2 programming menu:
1. Access to a Pr1 menu by pressing both SET+DOWN keys for 3 sec, the first parameter label will be
showed;
2. Press DOWN key till the Pr2 label will be showed, then press SET;
3. The blinking PAS label will be showed, wait some seconds;
4. Will be showed “0 - -” with blinking 0: insert the password [321] using the keys UP and DOWN and
confirming with SET key.
GENERAL STRUCTURE: The first two item rtC and EEV are related to submenus with others parameters.
SET+UP keys on rtC or EEV submenus allow coming back to parameter list,
SET+UP keys on parameter list allow immediate exit.
8.2 HOW TO MOVE PARAMETER FROM PR1 TO PR2 AND VICE VERSA
Enter on Pr2; select the parameter; press together [SET + DOWN]; a left side LED ON gives to the parameter the
presence on Pr1 level, a left side LED OFF means that the parameter is not present on Pr1 (only Pr2).
9. FAST ACCESS MENU
This menu contains the list of probes and some values that are automatically evacuate by the board such as the
superheat and the percentage of valve opening. The values: nP or noP stands for probe not present or value not
evacuate, Err value out of range, probe damaged not connected or incorrectly configured.
Entering fast
access menu
By press and release the UP arrow. The duration of the menu in
case of inactivity is about 3 min.
The values that will be showed depend on the configuration of the
board.
Use
or
arrows to
select an
entry,
then press
to see the
value or to
go on with
other value.
HM Access to clock menu or reset of the RTC alarm;
An Value of analog output;
SH Value of superheat. nA = not Available;
oPP Percentage of valve opening.
dP1 (Pb1) Value read by probe 1.
dP2 (Pb2) Value read by probe 2.
dP3 (Pb3) Value read by probe 3.
dp4 (Pb4) Value read by probe 4.
dP5 (Pb5) Temperature read by probe 5 or value obtained from pressure transducer.
dP6 (Pb6) Value read by probe 6.
dPP Pressure value read by (Pb5) transducer.
rPP Virtual pressure probe, only on slave.
L°t Minimum room temperature;
H°t Maximum room temperature;
dPr Virtual probe for room temperature regulation [rPA and rPb];
dPd Virtual probe for defrost management [dPA];
dPF Virtual probe for fan management [FPA];
rSE Real thermoregulation set point: the value includes the sum of SET, HES and/or the
dynamic set point if the functions are enabled.
Pressed together or wait the timeout of about 60 sec
10. MENU FOR MULTIMASTER FUNCTION: SEC
The function “section” SEC is enabled when icon is lit. It allows entering in the remote programming mode,
from a keyboard not physically connected to the board, through the LAN functionality.
Press UP arrow for about 3 sec, the icon will be ON.
The menu to change the section will be entered. SEC label
will be displayed.
Press SET to confirm. The following list will be available to
select the proper network function.
To gain access only to the local device.
To gain access to all the devices connected to the LAN.
To gain access to the device with 1st Adr (*)
…
To gain access to the device with 8th Adr (*)
Select and confirm an entry by pressing SET button.
Press SET and UP together or wait about 10 seconds.
(*) The devices on the LAN are indexed by using the Adr parameter (in ascending order).
EXAMPLES:
1. To modify the same parameter values in all the devices connected to the LAN: enter multimaster menu.
Select and confirm ALL. Exit from multimaster menu. Enter the programming menu and change the
required parameter values.
The new values will be changed on all devices connected to the LAN.
2. To modify a parameter value in the device with [Adr = 35]: find the relevant indexed section (the one
linked to [Adr = 35]). Enter multimaster menu. Select and confirm this section from the multimaster menu.
Exit from multimaster menu. Enter the programming menu and change the required parameter value.
3. If the alarm nod is present: enter the multimaster menu. Select and confirm the LOC section. Exit from
multimaster menu.
AT THE END OF THE PROGRAMMING PROCEDURE, SELECT THE SECTION “LOC”. IN THIS WAY
THE ICON WILL BE SWITCHED OFF!!
10.1 SYNCHRONIZED DEFROST
The synchronized defrost allow to manage multiple defrost from different boards connected through the LAN
connection. In this way, the boards can perform simultaneous defrosts with the possibility to end them in a
synchronized way.
The Adr parameter cannot be duplicated because in this case the defrost cannot be correctly managed.
Press for 3 seconds, the rtC or other will be showed. The
measurement unit blinks.
Press more than once the DOWN arrow to find the Adr parameter,
the press SET.
Set the value of Adr parameter, then press SET to confirm the
parameter.
Press the two keys together to exit from menu or wait for about 10
seconds.
The LSn and LAn parameter are only to show the actual settings (read only). Se the following example of
configuration:
DAILY DEFROST FROM RTC: : [cPb = y] & [EdF = rtC]
IdF Parameter: for safety reason force the value of Idf at +1 respect to the interval between two Ld parameters.
The IdF timer is reinitialized after defrost and at every power-on.
DEFROST START: at the time selected by the parameters Ld1 to Ld6 or Sd1 to Sd6.
DEFROST END: if the probes reach the dtE temperature or for maximum MdF time.
SAFETY and RtC or RtF ALARM: with clock alarm the device will use the parameter IdF, dtE and MdF.
WARNING: don’t set [EdF = rtC] and [CPb = n].
MULTIMASTER DEFROST: all the probes with clock
