6. โหมดการทำงาน

The TC818 offers four distinct operating modes to suit various temperature control needs. Press the "MODE" button to cycle through them.

6.1. TC Mode (Temperature Control)

This is the basic temperature control mode. You set a start temperature (ON) and a stop temperature (OFF). The device will turn on/off the connected appliance to maintain the temperature within this range.

• บรรทัดที่ 2: อุณหภูมิปัจจุบัน
• บรรทัดที่ 3: Temperature to Start Adjusting (ON)
• บรรทัดที่ 4: Temperature to Stop Adjustment (OFF)

วิธีการตั้งค่า:

1. Press "MODE" until "TC mode" is displayed.
2. Press "SET". The "Start Temperature" (ON) value will flash.
3. Use "UP/CLK" and "DOWN" to adjust the desired start temperature.
4. Press "SET" again. The "Stop Temperature" (OFF) value will flash.
5. Use "UP/CLK" and "DOWN" to adjust the desired stop temperature.
6. Press "MODE" to confirm and exit settings.

6.2. TC + Timer Mode (Temperature Control with Time Periods)

This mode combines temperature control with a clock function, allowing you to set different temperature ranges for up to three distinct time periods throughout the day.

• บรรทัดที่ 2: Current TC/Temperature/Time (displayed in turn)
• บรรทัดที่ 3: Current TC, Temperature to Start Adjusting
• บรรทัดที่ 4: Current TC, Temperature to Stop Adjustment

วิธีการตั้งค่า:

1. Press "MODE" until "TC+Timer mode" is displayed.
2. Press "SET". The setting content will flash.
3. You will set parameters for three time periods (TC 1, TC 2, TC 3). For each period, you will set:
   • เวลา: The start time for this period.
   • อุณหภูมิเริ่มต้น: The temperature to turn on the appliance.
   • อุณหภูมิหยุดทำงาน: The temperature to turn off the appliance.
4. Use "UP/CLK" and "DOWN" to adjust values. Press "SET" to move to the next parameter.
5. After setting all parameters for TC 1, press "MODE" to confirm and move to TC 2, and then TC 3.
6. Press "MODE" after setting TC 3 to save all settings and exit.

Note: The start time of TC 2 is the end time of TC 1. The start time of TC 3 is the end time of TC 2. The start time of TC 1 is the end time of TC 3.
