9.2.- Defrost control
Defrost start-up
Defrost is initiated if:
-Time scheduled in parameter d0 has passed since the beginning of last defrost.
-The N key is pressed for 5 seconds.
Defrost type
By resistors: The defrost resistors start up and the compressor stops; defrost is the result of heat from the resistors.
Fans will be running or not depending on parameter F3.
Drip time
Parameter d9 sets drip time and the time added at the end of defrost cycle to allow for drainage of the remaining
water in the evaporator. During this time the compressor and fans will not be running (unless defrost is by air).
Defrost termination
The defrost will terminate if:
-The temperature programmed in parameter d4 has been reached in probe 2 Probe 2 must be activated (P4).
In the event of probe 2 failure, defrosting will be complete once the maximum time has elapsed (d1)
-Time set in parameter d1 has passed (maximum duration of defrost).
-The H key is pressed for 5 seconds.
Message displayed during defrost
Set by parameter d2, with the choice of showing the actual temperature detected by probe 1 (d2=0), displaying
the temperature detected by probe 1 at the start of defrost (d2=1) or displaying the DEF message (d2=2). The d3
parameter defines the time during which the message is displayed, once the drip time (d9) and the fan stop time
(F4) is over.
