8. Parameter
locking:
Press ~
button for 6 seconds,
when "OFF" is displayed
and flashes,
it means set temperature
is locked,
the set temperature
just can be checked
and can not be modified;
when
"0
"is displayed
and flashes,
it
means unlocking.
Function
details
I. Temperature
Control
• After turning
on for the delay time ,the compressor
starts operating
when cold-room
temperature;::':
(set
temp
Hysteresis),
and will be off when cold-room
temperature
~ set temperature.
• To protect the compressor,
it can not be re-started
unless the time when the compressor
stops every time is
longer than the delay time(Parameter
E4).
2. Defrosting
Functions
• It defrosts
only if the temp.ofthe
evap.sensor
is less than the defrost termination
temp.(Parameter
F3)
• Operating
after a defrost
interval
time it will automatically
enter the status of defrost.
If the temperature
of evap. sensor is less than the defrost termination
temperature,
the defrost LED will turn on, and the
compressor
will stop.
• When the temp. of the evap. Sensor is over the temp. of defrost termination;
or the defrsot duration
ends,
the compressor
will exit the defrost status. After two minutes
dripping
time it will enter in the normal
status of refrigeration.
• When the defrost interval
time is set to "00" , the function
of automatic
defrost will be cancelled.
3. Display during defrost
• When setting the parameter
F4= l,the room temp. is locked during defrost,
and the last value before
defrost is displayed.
When defrost ends, normal display will be resumed
after 20 minutes
delay of room
temp. display. The defrost LED flashes during the delay.
4. Abnormal
work mode
• When the room sensor is short-circuited
or overheated
(more than ISO'C / lS0r)
"HH" is displayed;When
the room sensor is open-circuited
or temperature
is too low (less than -4S'C
/ -4Sr)
"LL" is displayed.
At that time the compressor
automatically
works by the cycle of 4S minutes
on and IS minutes
off.
• When the Evap. sensor fails or over the displayed
range, the defrost termination
will be just controlled
by
the defrost duration.(Parameter
F I)

Notes
for Installation
I. The sensor cable leads must be kept separately
from main voltage wires in order to avoid high frequency
noise induced.
Separate
the power supply of the loads from the power supply of the controller.
2. When install the sensor, it shall be placed with the head upward and the wire downward;
The evaporator
sensor must be installed
between
the fins of the evaporator
in the area, where probably
the ice is the
thickest.
Don't place the evaporator
sensor near the electric
heater.
3. In case of long-distance
sensor installation
from the controller,
the sensor cable may be prolonged
up to
100 m max. without any re-calibration.
4. The temperature
controller
can not be installed
in the area with water drops.
Accessories
for the temperature
controller
I. One attached
transformer
2. Two temperature
sensors
3. One installation
stand
4. One cover panel and I <I>
3 X I Omm screw
