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.
