Controller is used to maintain T temperature with desired hysteresis T in cooling or heating
devices. Actuator control is carried out by the relay output and the temperature measurement is
made by the chamber temperature sensor. The second temperautre sensor is applied in cooling

5. GENERAL DESCRIPTION.
5.2 DEFROSTING.
5.3. EVAPORATOR FAN.
5.1. ADJUSTMENT.
Depending on the application, select the type of periodical defrosting of the evaporator:
-natural(F36=0;F37=0;F38=ON)
-duetoelectricheaters(F36=0or1;F37=0;F38=ONorOFF)
-duetohotgas(F36=0or1;F37=1;F38=ONorOFF)
Defrostingcontroliscarriedoutautomaticallyandturnedon:
-periodicallyfromtimetotime(F35=1)
- depending on the total operation time of the compressor (F35=2). (The lower capacity of the
coolingsystem,thelessoftemdefrostingcyclesfollow)
-atcertaintimesduringtheday(max6cyclesperday).

Indifficultoperationconditions,whenthereisaneed foradditionaldefrostingoftheevaporator,the
process can be started manually by pressing button for 5 seconds. Defrosting diode flashes
whendefrostingmanually.
Depending on the needs, evaporator fan can operate in one of the seven operation modes
described in the “fan” section in point 4.3. The fan operation is dependent from compressor
operation or the evaporator temperature sensor. Due to advanced settings you can choose the
optimalfanoperationmodeandgetahigh cooling efficiency. During defrosting, fans are operating
or are turned off. Parameter F38 specifies this mode. When natural defrosting, it is recommended
toturnonthefantoraisetheefficiencyoftheoperation.
5.4. BISTATE INPUT.
The controller has a bistate input D1 to indicate emergency states, e.g system failure, pressure
control or safety thermostat activation, etc. The type of the input (normally close/opened) is
programmed by F50 parameter. After bistate input activation, the controller turns off the outputs,
turns on the beeper and the display indicates A11 code. Emergency states signalling can be
maintained,untilthealarmresetbyusingthebuttons(F50=2or4).

Minimum compressor stoppage time. It also means the delay time of switching the compressor after giving power supply.
Parameter protects the compressor against too frequent switching in case of power failure.

Operation and stoppage time of the compressor after chamber sensor failure is determined
on the basis of these two parameters.
Operation time: ton = F22xF23 ; Stoppage time: toff = F23-ton
Example: F22=20%; F23=60min then ton = 12min ; toff = 48min

Fan operation. There are 7 fan operation modes available: OFF - fan turned off.
1 - fan runs parallel to the compressor, is switched on after running the compressor with F42 delay and turned off after its stoppage with F43 delay.
2 - fan runs parallel to the compressor, is switched on before the running of the compressor with F42 lead and turned off after its stoppage with F43 delay.
3 - fan operates according to the evaporator temperature sensor, is activated when the value drops below the temperature F44 and turned off when
the evaporator sensor temperature rises above the value: F44+F45
4 - fan operates according to the evaporator temperature sensor, is activated when the value rises above temperature F44 and turned off,
when the evaporator sensor temperature drops below the value: F44-F45
5 - fan runs with the compressor. During the stoppage of the compressor, fan operates periodically: turned on for F46 time, turned off for F47 time.
Attention! During defrosting, the fan operation is specified by F38 parameter.
