Defrost start
Defrost will start if:
Ÿ
The time programmed in the
Defrost frequency
parameter has passed since the start of the last defrost.
The parameter
Defrost mode
defines how this time is counted:
ž
Frequency:
Total time passed between defrost starts.
ž
Compressor sum:
Total time of the compressor operating between defrost starts.
ž
Real Time Clock:
Defrost starts when one of the times programmed in the
Defrost 1
to
8
on
the
u
menu is reached. (The defrost frequency is not taken into account).
Ÿ
We press the
N
key for 5 seconds.
End of defrost
The defrost stops if:
Ÿ
The temperature programmed in the
Defrost final temperature
has been reached in probe 2 (this requires
having a defrost probe connected to S2).
Ÿ
The time configured in the
Defrost duration
has passed (maximum defrost duration). The
I
icon is shown on
the display if the
Signals end defrost time
parameter is configured in “Yes”.
Ÿ
We press the
N
key for 5 seconds.
REMARK:
If the
Defrost duration
is configured to 0, no defrosts are carried out.
Drip time after defrost
This is establishing using the
Drip time
parameter of the
H
menu and defines the time added at the end of the defrost
to allow removing any water left in the evaporator.
During this time, the compressor and fans will be stopped (except if the defrost is by air).
Message displayed during defrost
This is established using the
Defrost message
parameter, and you can choose between displaying the real
temperature captured by probe 1, show the temperature capture by probe 1 at the start of the defrost, or display the
DEFROST message.
The
Message duration
parameter defines how long this message is displayed, after the drip time and start up delay of
the fans (See page 15).
Other parameters
Using the
Defrost at Start-up
parameter, you can configure if the unit carries out or not a defrost when it receives
power (first start up or after a fault in the power supply).
If the "YES" option is chosen, defrost starts after the time defined in the
Defrost delay at Start-up
parameter on the
H
menu.
2nd defrost
It operates in the same way as the defrost, but acts on the auxiliary relay, controlled by probe 2 or 3 and is used to
control the defrost in a second evaporator. (The AUX relay must be configured as 2nd defrost).
The configuration parameters of the 2nd defrost are configured from the
v
menu.
Remote defrost
This function allows activating the defrost of the unit using an external button, connecting it to one of the digital inputs
that must be configured as "remote defrost”.
