H2: Disable keypad and/or remote control
Parameter ‘H2’ can be used to inhibit some functions relating to the use of the keypad, for example, the modi cation of the parame-
ters and the set point if the unit is accessible to the public.
The following options are available:
Parameter “H2” 0 1 2 3 4 5 6

Tab. 7.n
When the set point modi cation and parameter modi cation functions are inhibited, neither the set point nor the type F parame-
ters can be changed, while their values can still be displayed. The type C parameters, however, being password protected, can also
be modi ed from the keypad, following the procedure described previously. With the remote control disabled, only the values of
the parameters can be displayed, but they cannot be modi ed; in addition, the mute, defrost, continuous cycle, aux (auxiliary 1),
light (auxiliary 2) and on/o functions are disabled. Warnings: If H2=2 or H2=3 is set on the remote control, this is immediately
disabled. To re-enable the remote control, set H2=0 or H2=1 on the keypad.
Default: H2=1=> all enabled
H3: Enabling code for programming from the remote control
Parameter H3 assigns an access code to the remote control. As already described, this allows the remote control to be used when
there is more than one controller present on the same panel, without the risk of interference. For further details, see the paragraph
on the use of the remote control.
Default: H3=00 => programming from the remote control without code.
H4: Disable buzzer
This parameter can have two values:
H4=0 buzzer enabled;
H4=1 buzzer disabled
Default: H4=0=> buzzer enabled. Available on all models.
H5: AUX2 operating mode
See parameter H1, however referring to the auxiliary logical output (or relay 5).
H6: Lock keypad
Using the corresponding bits, the functions relating to the individual buttons on the keypad can be enabled/disabled, according to
the following relationships:
Total (value of parameter H6): to calculate the value to be assigned to parameter H6, simply sum the values assigned to the
functions that should be disabled.
For ir33, ir33power and ir33DIN see Table 7.q, for powercompact, powercompact small and mastercella see Table 7.q.
Important: the functions disabled using parameter H6 are added to those disabled using parameter H2.
Example: disable the “SET button”, “AUX button”:
ir33, ir33power and ir33DIN: 1+4 = 5 = value or parameter H6;
powercompact, powercompact small and mastercella: 1+32 = 33 = value of parameter H6.

Default: H6=0 => all buttons disabled.
H7 (masked parameter)
‘H7’=0 => Use the standard keypad.
‘H7’=1 => Use the MODIFIED keypad.
This parameter selects the type of keypad used on the controller. Two types of keypads are available: STANDARD and MODIFIED.
The choice of the type of keypad determines the visibility to the user of the HACCP and %rH (relative humidity percentage)
functions.
The functions of the standard keypad are those described thus far.
The MODIFIED keypad shifts the HACCP functions to the combination of buttons SET and
and enables the %rH function
(for further information, contact CAREL).
As for the standard keypad, the functions of the individual buttons can be disabled using parameter ‘H6’.
Default: ‘H7’=0 => Use the standard keypad.
