2. APPLICATION
• Counters
• Refrigerating balconies
- Power supply:
The
is a temperature controller for freezing goods with two stages for freezing. It also
commands the evaporator fans and manages the defrosting cycles.
It includes two independent hourmeters for counting the refrigeration output operation time. When the
programmed amount of hours before maintenance is reached (ex: compressors) a display indication is
given.
In order to increase the system efficiency, the
allows the adjustment of a pre-defrosting
time, which enables the collection of remaining gas before starting the defrosting cycle.
Product complies with CE (European Union) and UL Inc. (United States and Canada).

4.3 - Parameters description
F01 - Access code (123)
To change the parameters it is necessary to use the access code.It is not necessary to use the access
code to visualize the adjusted parameters.
Attention, the defrost will only initiate if the temperature in S2 (sensor of the evaporator) will be lesser of
what the indicated one in F13.
F10 - Compressor delay after off (off-on)
F11 - Compressor status with detached ambient sensor (S1)
F12 - Defrost when the instrument is powered on
It is the minimum time that compressor will keep off, it means, space of time between the last stop and
the next drive. It serves to alliviate the discharge pressure and to increase the time of useful life of the
compressor.
If the room sensor (S1) will be danified or outside the specified range, the compressor assumes the
configured status in this function.
Example: For counters of fruits, it is better to keep the compressor off. In counters of meat it is better to
keep the compressor on.
It makes possible the accomplishment of a defrost at the moment that controller is energized, for
example, in the return of electrical energy (in case of energy lack)
F09 - Compressor delay after on (on-off)
It is the minimum time that compressor will keep on, it means, space of time between the last drive and
the next stop. It serves to prevent high voltage events in the electric network.

F02 -
It is the difference of temperature (hysteresis) between to turn OFF and turn ON the 1st stage (REF1).
Example: To control the temperature in 4.0°C with differential of 1.0°C. Soon, the refrigeration will be
turned off in 4.0°C and turned on again in 5.0°C (4.0 + 1.0)
Control differential for the 1st stage (hysteresis 1)
F03 -
F04 - Minimum setpoint allowed to the end user
F05 - Maximum setpoint allowed to the end user
F06 - Delay when the instrument is powered on
F07 - Act point of high room temperature alert
08 - Refrigeration time (interval between defrosts)
It is the difference of temperature (hysteresis) between to turn OFF and turn ON the 2nd stage (REF2).
Electronic limits whose purpose is prevent that too high or too low setpoint temperatures are regulated.
When the instrument is powered on, its control is kept disabled during a time, delaying the start of
process. During this time, it works only as temperature indicator. It serves to prevent demand of electric
energy peaks, in case of lack or return of the same and when exists a lot of equipment connected on the
same net. For this, just adjust different times for each equipment. This delay may be of compressor or
defrost (when exist defrost on turn on).
If the room temperature (sensor S1) reaches this point during refrigeration, this will be signaled visually
through the indication blinking on display.
It is the time which compressor will turn on and turn off only for room temperature and starts to be
counted when the fan is turned on , after fan-delay stage (fan return after draining).
