5. સેટઅપ અને ઇન્સ્ટોલેશન
5.1 માઉન્ટ કરવાનું
- Choose a suitable location for mounting the controller, away from direct heat sources, moisture, and vibrations.
- યુનિટની આસપાસ પર્યાપ્ત વેન્ટિલેશનની ખાતરી કરો.
- Cut a rectangular opening in the panel according to the controller's dimensions (refer to the product diagram for exact measurements).
- Insert the controller into the opening and secure it using the provided mounting clips.
5.2.૨.૨ વાયરિંગ
ચેતવણી: Ensure power is disconnected before wiring.
- પાવર સપ્લાય: Connect the main power supply (L and N) to the designated terminals on the controller.
- તાપમાન સેન્સર: Connect the NTC temperature sensor to the sensor input terminals. Ensure correct polarity if applicable. The sensor should be placed in the area where temperature needs to be monitored and controlled.
- Compressor Output: Connect the compressor's power line to the compressor relay output terminals.
- Defrost Heater Output: Connect the defrost heater's power line to the defrost relay output terminals.
- પંખો આઉટપુટ: Connect the evaporator fan's power line to the fan relay output terminals.
Refer to the wiring diagram printed on the side of the controller or in the specific model's manual for precise terminal connections.
6. ઓપરેટિંગ સૂચનાઓ
6.1 પાવર ચાલુ/બંધ
- To power on, connect the main power supply. The display will show the current temperature.
- To power off, disconnect the main power supply.
6.2 Viewઆઈએન તાપમાન
The current measured temperature is continuously displayed on the front panel.
6.3 પરિમાણો સુયોજિત કરવા
The controller allows adjustment of various parameters such as setpoint temperature, differential, defrost cycle, and fan operation. The exact procedure may vary slightly by model, but generally follows these steps:
- દબાવો અને પકડી રાખો સેટ/ઓકે button for 3-5 seconds to enter parameter setting mode.
- નો ઉપયોગ કરો UP અને નીચે buttons to navigate through the parameter codes (e.g., F1, F2, P1, P2).
- દબાવો સેટ/ઓકે થી view પસંદ કરેલ પરિમાણનું મૂલ્ય.
- નો ઉપયોગ કરો UP અને નીચે મૂલ્યને સમાયોજિત કરવા માટે બટનો.
- દબાવો સેટ/ઓકે again to confirm the new value and move to the next parameter, or press and hold સેટ/ઓકે to save all changes and exit the setting mode.
Common parameters include:
- Set Point (SP): The desired temperature.
- Differential (Hy): The temperature difference between the set point and the turn-on/off temperature.
- Defrost Cycle (Id): Interval between defrost cycles.
- Defrost Duration (Ed): Length of the defrost cycle.
- Fan Control (Fc): Settings for fan operation during refrigeration and defrost.
7. જાળવણી
7.1 સફાઈ
- Regularly clean the front panel with a soft, damp કાપડ ઘર્ષક ક્લીનર્સ અથવા સોલવન્ટનો ઉપયોગ કરશો નહીં.
- Ensure the ventilation openings are free from dust and debris to prevent overheating.
