Smart Defrost
The Beacon II Smart Controller continuously monitors
the system performance to determine the need for
defrost. It uses a variety of data such as the outdoor
ambient and box temperature in its decision making
process. A defrost cycle will only be triggered at a
programmed defrost time if the system determines
a defrost is necessary. Defrost times will NOT
automatically trigger a defrost cycle, unless the needs of
the system call for one.
Activating Smart Defrost:
You must program multiple defrost times into the Smart
Controller to provide flexibility for the system to defrost
the coil properly. Smart Defrost will only allow the
system to defrost at a programmed defrost time. The
system will not defrost in between programmed defrost
times. Hence, we recommend that a minimum of 8
defrost periods be programmed when Smart Defrost is
turned on. The system will not defrost eight times per
day but with this many defrost periods it will have better
options to keep the coil clear.
To activate Smart Defrost, press the “PROG REVIEW”
button until “SMTDFT” is displayed.
Move the “SETPOINT” slide-bar to “ON” then press
“ENTER”. Press “CLEAR” to return to the main screen.
For version 1.2., when Smart Defrost is turned
on, 8 defrost periods per day will automatically
be programmed. These will be at 12:00 am,
3:00 am, 6:00 am, 9:00 am, 12:00 pm, 3:00 pm,
6:00 pm, and 9:00 pm. Also, the defrost fail safe
time will be set to 60 minutes, and the defrost
termination temperature will be set to 55°F.
The user can change these as needed for the
application.
Deactivating Smart Defrost:
To turn Smart Defrost off move the “SETPOINT” slide-
bar to “OFF” then press “ENTER”. Press “CLEAR” to
return to the main screen.
