4.2. Tilslutningstrin

1. Strømforsyning: Connect the 12V DC power supply to the designated input terminals on the controller. Ensure correct polarity (positive and negative).
2. Temperatursensorer: Connect the two waterproof NTC 10K sensors to the 'Sensor1' and 'Sensor2' input terminals. The sensors are non-polar and can be connected in either orientation.
3. Outputenheder: Connect your heating or cooling devices (e.g., heaters, fans, pumps) to the 'Output1 Power' and 'Output2 Power' terminals. Each output can handle up to 10A. Ensure the devices are compatible with 12V DC power.
4. Sikre forbindelser: Double-check all wiring to ensure secure connections and prevent short circuits.

Warning: Incorrect wiring can damage the device or connected equipment. Always disconnect power before making or changing any connections.

5. Betjening

The W1088 controller features two independent temperature control channels (OUT1 and OUT2), each with its own display and control buttons.

5.1. Setting the Starting Temperature (OUT1 / OUT2)

1. Tryk på UP button once for the desired channel (OUT1 or OUT2) to display the current starting temperature setting.
2. Tryk længe på UP button for approximately 3 seconds until the displayed temperature flashes.
3. Brug UP og NED buttons to adjust the starting temperature to your desired value.
4. The setting will automatically save after a few seconds of inactivity, or you can press any other button to confirm.

5.2. Setting the Stopping Temperature (OUT1 / OUT2)

1. Tryk på NED button once for the desired channel (OUT1 or OUT2) to display the current stopping temperature setting.
2. Tryk længe på NED button for approximately 3 seconds until the displayed temperature flashes.
3. Brug UP og NED buttons to adjust the stopping temperature to your desired value.
4. The setting will automatically save after a few seconds of inactivity, or you can press any other button to confirm.

5.3. Accessing Setting Mode (P0 Parameters)

To access advanced settings (e.g., temperature delay, calibration), follow these steps:

1. Simultaneously press and hold both the UP button of OUT1 and the UP button of OUT2 for approximately 3 seconds.
2. The display will show 'P0', indicating entry into the setting mode.
3. Brug UP og NED buttons of either channel to navigate through the P-parameters (P0, P1, P2, etc.).
4. To modify a parameter, press the UP or NED button of the corresponding channel. The value will flash.
5. Adjust the value using the UP og NED knapper.
6. Press any other button or wait for a few seconds to save the setting and exit the parameter editing.
7. To exit the setting mode, long press the UP button of OUT1 and the UP button of OUT2 simultaneously again, or wait for a period of inactivity.

Note:

• If the starting temperature is set higher than the stopping temperature, the controller will operate in køletilstand.
• If the starting temperature is set lower than the stopping temperature, the controller will operate in opvarmningstilstand.

6. Vedligeholdelse

• Rensning: Gently wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Sensorpleje: Ensure the temperature sensors are kept clean and free from debris that could affect readings. Avoid bending the sensor cables sharply.
• Miljøforhold: Operate the controller within its specified temperature and humidity ranges to ensure longevity. Avoid direct sunlight or extreme temperatures.
• Strømafbrydelse: Afbryd altid strømmen, før du udfører vedligeholdelse eller rengøring.
