9. REAL TIME CLOCK AND DEFROST SETUP

9.1. Setting and Displaying the Real Time Clock

The Real Time Clock (RTC) operates on a 24 hour cycle (00:00...23:59)
The current time set in the RTC can be displayed by depressing and holding the
CLOCK key. The display will show the standard format (24 hours) of: HH.MM
(hours. minutes)
Procedure:
1. To set the Real-Time clock press and hold the SET Key for 15 seconds until
the three front panel COMPRESSOR, DEFROST and FAN LEDs switch on
and off in sequence and SEtP is displayed (with this procedure one enters
the parameter configuration menu).
2. Repeatedly press the SET key until 'tINE' is displayed followed by current
time value. Use the UP and DOWN arrows to set clock as required.
3. Press SET to confirm new value.

9.2. Setting the Daily Defrost Cycles on the Real Time Clock

It is possible to set-up 6 defrost cycles per day on Icon models: ICON-343C &
ICON-363C.
The time parameters regarding this function are: tIN1, tIN2, tIN3, tIN4, tIN5 & tIN6
Notes:
1. In order to activate a defrost cycle it is necessary to set the defrost cycle
starting time in at least one of the parameters (tIN1, tIN2, tIN3, tIN4, tIN5 or
tIN6)
2. To be recognized as valid the time must be set in the format of HH.MM, (24
hours)
3. If parameters tIN1...tIN6 are set to - - . - - then function is DISABLED.
Procedure:
1. To set the timed defrost press and hold the SET Key for 15 seconds until
the three front panel COMPRESSOR, DEFROST and FAN LEDs switch on
and off in sequence and SEtP is displayed (with this procedure one enters
the parameter configuration menu).
2. Repeatedly press the SET key until 'tIN1' is displayed followed by current
value. Use the UP and DOWN arrows to set defrost start time as required.
3. Press SET to confirm new value.
4. Repeat steps 1 to 3 for tIN2...tIN6.
Important:
With regard to parameter dCSt, (time interval between defrost cycles), please
remember that the value set in said parameter (dCSt) must be greater than the
maximum set interval between two defrost cycles start times set in parameters
tIN1...tIN6.
Example: tIN1 = 05.00
TIN3 = 15.30
TIN5 = - -.- -
Therefore: dCSt > 18 hours 50 mins.
23
tIN2 = 11.30
tIN4 = 23.50
tIN6 = - -.- -
