5. Operating Instructions
The controller features a large LCD display and three buttons: SET, CLOCK, è Frecce SU/GIÙ.
5.1 Impostazione di l'ora attuale
- Appughjà è tene premutu CLOCK per 3 secondi finu à chì a cifra di l'ora lampeggi.
- Aduprà u Frecce SU/GIÙ per aghjustà l'ora.
- Press CLOCK again to move to the minute digit, then adjust with Frecce SU/GIÙ.
- Press CLOCK per cunfirmà è esce.
5.2 Temperature Control (Outlets 1 & 2)
Outlets 1 and 2 are independently controlled for temperature. Each can be set for heating or cooling mode with specific ON/OFF temperatures and operating times.
- Appughjà è tene premutu SET button for 3 seconds to enter programming mode. The display will show 'OUT1' or 'OUT2' and the first setting will flash.
- Aduprà u Frecce SU/GIÙ to select 'OUT1' or 'OUT2'. Press SET per cunfirmà.
- Set ON Time: The 'ON' time will flash. Use Frecce SU/GIÙ per stabilisce l'ora, poi appughjà SET to set minutes. This is the time when temperature control for this outlet begins.
- Set OFF Time: The 'OFF' time will flash. Use Frecce SU/GIÙ per stabilisce l'ora, poi appughjà SET to set minutes. This is the time when temperature control for this outlet ends.
- Set ON Temperature: The 'ON Temp' will flash. Use Frecce SU/GIÙ to set the temperature at which the connected device turns ON.
- Set OFF Temperature: The 'OFF Temp' will flash. Use Frecce SU/GIÙ to set the temperature at which the connected device turns OFF.
- Determine Mode (Heating/Cooling):
- If ON Temp < OFF Temp: The controller operates in Modu di riscaldamentu. The device turns on when the temperature drops to ON Temp and turns off when it reaches OFF Temp.
- If ON Temp > OFF Temp: The controller operates in Modu di raffreddamentu. The device turns on when the temperature rises to ON Temp and turns off when it reaches OFF Temp.
- Press SET to cycle through additional settings (High Alarm, Low Alarm, Calibration) or press CLOCK per salvà è esce.

5.3 Timer Control (Outlet 3)
Outlet 3 operates as a simple timer, allowing for two independent ON/OFF periods within a 24-hour cycle.
- Appughjà è tene premutu SET button for 3 seconds to enter programming mode.
- Aduprà u Frecce SU/GIÙ to select 'OUT3'. Press SET per cunfirmà.
- Set First ON Time: The 'ON' time for the first period will flash. Adjust with Frecce SU/GIÙ è cunfirmà cun SET.
- Set First OFF Time: The 'OFF' time for the first period will flash. Adjust with Frecce SU/GIÙ è cunfirmà cun SET.
- Repetite i passi per u Second ON Time è Second OFF Time if a second timed period is desired. If not, set the second ON time to be the same as the second OFF time to disable it.
- Press CLOCK per salvà è esce.

| Prublemu | Causa Possibile | Soluzione |
|---|---|---|
| U display hè viotu o ùn si accende micca. | Nisuna alimentazione elettrica. | Check if the controller is properly plugged into a live outlet. Verify the power outlet is functional. |
| Heating/Cooling device (OUT1/OUT2) not turning on/off. | Incorrect temperature settings (ON Temp/OFF Temp). Incorrect time period settings. Malfunzionamentu di u dispusitivu. | Review and adjust ON/OFF temperatures and time periods. Ensure the ON/OFF temperatures are set correctly for heating (ON < OFF) or cooling (ON > OFF). Test the connected device directly in a wall outlet. |
| Timed device (OUT3) not turning on/off. | Incorrect ON/OFF times for OUT3. | Verify the programmed ON/OFF times for Outlet 3. Ensure the current time on the controller is accurate. |
| E letture di temperatura sò imprecise. | Probe placement or damage. Calibrazione necessaria. | Ensure probes are correctly positioned and not directly touching heating elements. Check probes for visible damage. Use the calibration setting (refer to section 5.5) to adjust the temperature reading if necessary (within +/- 12°F). Note that readings are typically accurate within 1-2°F. |
| I paràmetri sò persi dopu una mancanza di correntetage. | This should not occur as the device has memory backup. | If settings are consistently lost, contact customer support. |
