DEFROST COMPUTING
21
Function: To set type of computation for
defrost time.
To change Defrost Computing
parameter, press the set key.
0 1 0
Use UP/DOWN keys to set desired
value.
0 = Total of real time.
Example
: This means that the time
calculation for defrost frequency will be
for the total hours the unit has been
running.
1 - Sum of total compressor operating
times.
This means that for time
calculation, the unit will add the total
time the compressor has been in an ON
mode.
It keeps a record of the hours /-1
Hour incase of a power failure.
Example : If Defrost frequency is set to 6
hrs. and 3 ½ hrs have passed after unit
has started and power fails, then defrost
cycle will stat after 3 hours when power
resumes.
