5. Setup
- Pjazzament: Position the display unit in a visible location. The outlet box can be mounted or placed securely.
- Installazzjoni tas-sonda: Place the temperature probe in the environment where temperature needs to be controlled. The probe is waterproof and can be submerged in water or placed in dry enclosures. Use the included suction cup for secure placement if applicable.
- Qabbad Apparat: Plug your heating device (e.g., aquarium heater, heat mat) into the outlet labeled 'HEAT'. Plug your cooling device (e.g., cooling fan, chiller) into the outlet labeled 'COOL'. Ensure total wattage ma jaqbiżx 1100W.
- Qawwa Mixgħul: Plug the controller's main power cord into a standard 110V AC electrical outlet. The display will illuminate, showing the current temperature.

6. Istruzzjonijiet Operattivi
The TC-321 allows you to set a target temperature and define temperature differentials for both heating and cooling modes. This ensures your environment stays within a desired range.
Setting Target Temperature and Differentials:

Image: Step-by-step visual guide on how to set the target temperature, cooling differential, and heating differential on the NICREW TC-321 display.
- Issettja t-Temperatura Mira:
- Agħfas u żomm il- SET button for 3 seconds. The display will show the current target temperature setting.
- Uża l- ▲ ('il fuq) jew ▼ (down) buttons to adjust the target temperature to your desired value (e.g., 76°F).
- Agħfas SET għal darb'oħra biex tikkonferma u tgħaddi għas-setting li jmiss.
- Set Cooling Differential (COOL DIFF):
- After setting the target temperature, the display will show 'COOL DIFF'.
- Uża l- ▲ or ▼ buttons to set the cooling differential (e.g., 4°F). This means the cooling device will activate when the temperature reaches Target Temp + Cool Diff (e.g., 76°F + 4°F = 80°F) and shut off when it returns to the Target Temp (76°F).
- Agħfas SET mill-ġdid biex tikkonferma.
- Set Heating Differential (HEAT DIFF):
- The display will now show 'HEAT DIFF'.
- Uża l- ▲ or ▼ buttons to set the heating differential (e.g., 1°F). This means the heating device will activate when the temperature drops to Target Temp - Heat Diff (e.g., 76°F - 1°F = 75°F) and shut off when it returns to the Target Temp (76°F).
- Agħfas SET one last time to save all settings and exit the programming mode.
The controller will now operate automatically to maintain the temperature within your set range.
Allarm tat-Temperatura:
The device includes a temperature alarm feature that activates if the temperature deviates significantly from your desired range, providing an alert for potential issues.
