Parameters for setting the AUX output activation time band
AOd
AUX output activation time band day setting
AOd= 0 no event set
AOd= 1…7 Monday to Sunday
AOd= 8 from Monday to Friday
AOd= 9 from Monday to Saturday
AOd= 10 Saturday & Sunday
AOd= 11 every day
AOh
AUX output activation time band start hours
AOm
AUX output activation time band start minutes
AFh
AUX output activation time band end hours
AFm
AUX output activation time band end minutes
Example:
To program the activation of the AUX output every day from
12.31 at 13.29, set: AOd=11 (days), AOh=12 (start hours), AOm=31 (start
minutes), AFh=13 (end hours) and AFm=29 (end minutes).
Important
Important
: the activation the AUX output activation time band is
linked to parameters H1=3 and A4≠6/7/8.
4.11 Rapid parameter set selection (EZY)
The easy and easy compact controllers feature the EZY parameter (on
the compact models, this is called EY), which is used to quickly choose
a list of parameters, with corresponding values, for the control of the
refrigeration system.
By setting parameter EZY=1, 2, 3, 4, one of the 4 lists made up of a
maximum of 25 parameters (for the lists see par. “5.8 Table of EZY
parameter sets” page 27). The values in the chosen list overwrite the
corresponding operating parameters.
Note
:
to restore the selected rapid parameter set at any time, turn the
controller off and on again, while holding SET. The display shows
“CE” to indicate that the selected rapid set (EZY= 1, 2, 3, 4) has again
overwritten the operating parameters, thus restoring the original set
of parameters;
to restore all the parameters and return to the original default values
(factory settings), turn the controller off and on again while holding
DOWN and SET, until the display shows “CF”. Use this procedure with
extreme care, as it may compromise the fundamental control settings;
EZY=0 brings no change;
on the thermometer models (PJEZM*), the EZY parameter (EY for the
easy compact models) is not featured.
4.12 Other settings
The operation of the device is completed by a series of additional
functions, such as the assignment of a supervisor serial network address,
the confi guration of the AUX relay, the enabling of the keypad and the
buzzer.
H0: serial address
Assigns the instrument an identifi cation address for connecting to a
supervisory or telemaintenance system (def. H0=1).
H1: AUX output confi guration
Establishes the operating logic of the auxiliary relay; in particular defi nes
whether it is used as an alarm output or as an auxiliary output linked to
the digital input.
H1= 0
no function associated with the output
H1=1
alarm output: norm. energised (relay de-energised with
alarm)
H1=2
alarm output: norm. de-energised (relay energised with
alarm)
H1=3
AUX output linked to Dig. in [A4=6/7/8]
Dig. in OPEN = AUX de-energised
Dig in CLOSED = AUX ene “AUX” LED on display

Note
:
in mode H1= 1/2, the alarms that act on the AUX output are: “LO”, “HI”,
“E0”, “IA”, “CHT”;
mode H1= 1 is useful for signalling an alarm when a power failure
occurs
H2: enable keypad
Used to prevent the set point and the other operating parameters
from being changed when the instrument is located in a place that is
accessible to the public.
H2= 0
keypad disabled:
- F parameters read-only
- C parameters modifi able (with password)
- no set point modifi cation
- no manual defrost
- no continuous cycle
- no ON/OFF
H2=1 keypad
enabled
H2=2
keypad enabled except for ON/OFF
H4: disable buzzer
Setting H4= 1 disables the operation of the audible buzzer.
H5: ID code
Display-only value: this can only be modifi ed via serial connection (key
or supervisor). When set to a positive value (values from 0 to 31 are used
by CAREL for the basic models), if a parameter, including the set point, is
modifi ed from the keypad, the value becomes negative. This allows any
modifi cations made the parameters compared to the initial settings to
be monitored.
PS: password
Protection code for modifying the confi guration parameters (default=
22). The value of the password can be customised from the supervisor.
