DESCRIPTION
ICE is an ideal thermostat for sprinkling ice machine. It has two NTC/PTC sensors: one is for the evaporator temperature and the other is for the ice bucket in order to terminate
the production when the bucket is full. It has 3 indication digits of temperature display with an accuracy of 0.5°C and 4 buttons. Three relays (for compressor 30Α, water pump
10Α, and defrost 10Α) with NO contact, three adjustable timers in minutes for the control of the compressor/water pump and defrost relays, electrical or HOT-GAS defrost
mode, OFF mode for the device and an alarm buzzer for high or low temperature. The device is mounted on a panel hole 29x71mm and it is restrained with plastic side brackets.
For more indications regarding the alarms please see the alarm’s table at page 3.
DEVICE OPERATION WITH ELECTRIC DEFROST
During start-up, the defrost relay is activated and timer t2 starts counting. The screen displays t2 time duration, which counts backwards, while the indications and
turn on. If the evaporator temperature is lower than the set point after the defrost, all operations and relays will be deactivated automatically and the screen will
display the indication “ΕΕΕ”. The alarm is automatically deactivated after the restart of the device using the ON/OFF button or by toggling the power supply. Manual defrost
duration is based on timer t2 and does not end based on the defrost end temperature –parameter dE5.
When timer t2 elapses, the defrost relay is deactivated and timer t3 starts counting while the compressor and water pump relays are activated. The display
shows the current evaporator temperature and the indications ,T2 and light up. When the evaporator temperature reaches the set point, timer t1 begins counting,
while the compressor and water pump relay remain activated until timer t1 elapses. The display shows time duration of timer t1, which counts backwards, while the indications
, and light up. When timer t1 elapses, the compressor and water pump relays are deactivated, and afterwards the cycle starts again with the activation of defrost
relay, etc.
If a malfunction occurs in the cooling circuit and the evaporator temperature does not decrease, the aforesaid process will end based on timer t3. All functions and relays
will be deactivated automatically and alarm "FFF" will be displayed. The alarm is automatically OFF by restarting the thermostat from the power supply or the ON / OFF
button.
When the ice bucket temperature sensor reaches the SP2, the production will stop when the last production of ice drops on the bucket and the cycle ends. On screen the
indication “FUL” is displayed until the bucket temperature reaches SP2+dF2 and the cycle resumes.
The aforesaid cycle repeats continuously without interruption during the smooth operation of the thermostat.
In case of evaporator’s temperature sensor failure or OFF device state, all thermostat functions are deactivated.
In case of bucket temperature sensor failure, the cycle continues and does not stop because of this failure.
HOT-GAS OPERATION
Parameter do set the defrost function in electric or HOT-GAS mode. Only in hot-gas defrost mode (do = 1), the compressor relay works in parallel with the defrost relay, for
time t2.
1. Press and parameter SP2 is displayed.
2. Press and its value is displayed while the arrows change its value.
3. Press to store the new value. Now the device is operating with the new value.
By pressing at the same time and , the device switches ON/OFF.
