USER PARAMETERS TABLE
This section describes the most commonly used parameters which are always visible (the access password
PA1
is not enabled by default).
For a description of all other parameters, see the user manual.
NOTE
: the user parameters ARE NOT divided into sub-folders and are always visible. The same parameters are also visible in the respective
folders ‘Compressor’, ‘Fans’, etc. (indicated also here to make the groupings clearer) in the password-protected Installer parameters menu.

Ont
Controller switch-on time in the event of faulty probe.
- if
Ont

OFt
Controller switch-off time in the event of faulty probe.
- if
OFt
= 1 and
Ont
= 0, compressor will always stay off (OFF).
- if
Ont
> 0 and
OFt
> 0, compressor operates in Duty Cycle mode.

dOn
Switch-on delay. The parameter indicates that a protection is active on the general compressor relay
actuations. At least the indicated time must elapse between the request and the actual activation of
the compressor relay.

dOF
Delay time after power-off: the delay time indicated must elapse between deactivation of the
compressor relay and the next power-on.

dbi
Delay time between power-ons; the delay time indicated must elapse between two consecutive
compressor power-ons.

DEFROST (dEF)
dtY
Defrost mode
0
= Electric defrost (defrost cycle OFF), or compressor not running during defrost.
NOTE
: electrical d air defrost, in the case of fans connected in parallel to the defrost output
relay.

= Compressor running time (DIGIFROST® method);
defrost active ONLY when the compressor is on.
NOTE
: compressor running hours are counted separately from the evaporator probe (count active also
when evaporator probe missing or faulty).
1
= Appliance running hours; defrost count is always active when machine is on and starts at each
power-up.
