2. Nastavení a instalace

Proper installation is crucial for the safe and effective operation of the W1609-101 temperature control. This device is designed for use with copper conductors only.

2.1 Montáž

• Select a suitable location for mounting the control unit, ensuring it is protected from excessive moisture and physical damage.
• Secure the unit using appropriate fasteners through the designated mounting holes. Refer to the mounting dimensions provided in the product documentation for precise placement.

2.2 Capillary Tube and Probe Placement

• The W1609-101 features a 5-foot copper capillary tube with a temperature sensing probe.
• Carefully route the capillary tube to the area where temperature is to be controlled. Avoid sharp bends or kinks in the tube, as this can damage the sensor.
• Position the temperature probe to accurately reflect the desired temperature of the controlled environment. Ensure it is not directly exposed to heating or cooling elements, which could lead to inaccurate readings.

2.3 Elektrické zapojení

• VAROVÁNÍ: Disconnect all power before wiring. Wiring should be performed by a qualified electrician in accordance with all local and national electrical codes.
• Connect the power supply (24 to 240VAC) and the controlled device (e.g., fan, compressor, heater) to the appropriate terminals on the control unit. Refer to the internal wiring diagram in the product documentation.
• Ujistěte se, že všechny spoje jsou bezpečné a řádně izolované.

3. Návod k obsluze

The W1609-101 temperature control is designed for straightforward operation using its rotary dial.

3.1 Nastavení teploty

• Locate the rotary dial on the front of the control unit.
• Turn the dial to select the desired temperature setpoint. The temperature range for this unit is -30°F to +90°F (-34°C to +32°C).
• The unit will activate or deactivate the connected device (e.g., heater or cooler) to maintain the temperature within the set range.

3.2 Differential Adjustment

• The differential adjustment allows you to set the temperature difference between the cut-in and cut-out points.
• The adjustable differential range is 3°F to 8°F. Adjust this setting as needed for your specific application to prevent rapid cycling of the controlled equipment.

3.3 Close on Rise Feature

This model features a "Close on Rise" characteristic, meaning the electrical contacts will close (activating the connected device) when the temperature rises above the setpoint, and open when the temperature falls below the setpoint (considering the differential). This is typically used for cooling applications where the compressor or fan needs to turn on when the temperature gets too high.

4. Údržba

To ensure long-term reliability and accurate performance of your Ranco W1609-101 Electronic Temperature Control, follow these general maintenance guidelines:

• Pravidelný úklid: Keep the exterior of the control unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using abrasive cleaners or solvents.
• Zkontrolujte kabeláž: Periodically check all electrical connections for tightness and signs of wear or corrosion. Ensure the capillary tube is undamaged and properly routed.
• Stav sondy: Verify that the temperature probe is clean and free from any buildup that could impede accurate temperature sensing.
• Odborná kontrola: For complex systems or if you suspect a malfunction, it is recommended to have the unit inspected by a qualified service technician.

5. Řešení problémů

If you encounter issues with your Ranco W1609-101, consider the following basic troubleshooting steps:

• Bez napájení:
  • Zkontrolujte hlavní napájení jednotky.
  • Ověřte, že jsou všechna elektrická připojení zajištěna.
  • Inspect fuses or circuit breakers in the power circuit.
• Nepřesné měření/regulace teploty:
  • Ensure the temperature probe is correctly positioned and not obstructed or damaged.
  • Verify that the temperature setpoint and differential settings are appropriate for your application.
  • Check for any damage to the capillary tube.
• Device Not Activating/Deactivating:
  • Confirm the temperature setpoint and differential are correctly configured relative to the ambient temperature.
  • Check the wiring to the controlled device.
  • If the unit is "Close on Rise," ensure it's being used in an appropriate application (e.g., cooling).

If these steps do not resolve the issue, contact a qualified service technician for further assistance.
