Do you have a question about the Sub-Zero INTEGRATED WINE Series and is the answer not in the manual?

The Sub-Zero Integrated Wine (IW) Series is a line of advanced wine storage units designed to preserve and protect wine collections. These units incorporate sophisticated electronic control systems to monitor, regulate, and display various functions, ensuring optimal conditions for wine storage.

Function Description:

The IW series units are primarily designed for storing wine at precise temperatures, with some models offering additional storage for other refrigerated items. They feature multiple temperature zones, allowing for different types of wine to be stored at their ideal conditions. The electronic control system, managed by a Main Control Board (also referred to as the Main “Controller” Board), utilizes a microprocessor, relays, and triacs to control all appliance functions. A User Interface Module (UIM), or Control Panel, allows for manual input and displays information via an LCD (Liquid Crystal Display). This system monitors temperatures using thermistors (temperature sensors) and can display them in either Fahrenheit (°F) or Celsius (°C). The units also include various safety and convenience features such as door/drawer alarms, accent lighting, and a Sabbath mode.

Important Technical Specifications:

The IW series units operate on 115Vac, 60Hz, 1 Phase power. Key components include:

Compressors: Responsible for the refrigeration cycle.
Condenser: Dissipates heat from the refrigerant.
Evaporators: Absorb heat from the storage compartments.
Filter-Driers: Remove moisture and contaminants from the refrigerant.
Heat-exchangers: Facilitate heat transfer.
Tubing: Carries the Freon refrigerant (R134A).
Electronic Control System Components: Including the Main Control Board, microprocessor, relays, and triacs.
Fan & Light Switches: For controlling internal fans and lighting.
Fan Motors & Blades: Circulate air within the unit and across the condenser.
Drain Pan & Drain Tubes: Collect and remove condensation.
Wiring: Electrical connections throughout the unit.
Light Sockets & Bulbs: Provide interior illumination.
Door Hinges: Allow for smooth door operation.
Compressor Electricals: Components related to compressor operation.
Thermistors: Temperature sensors located in the cabinet (CAB UPR, CAB LWR, REF CAB) and evaporator (EVAP UPR, EVAP LWR, REF EVAP) sections.
Refrigerant Charge: R134A.
Total Amps: Specified on the serial tag.

Usage Features:

Interactive Control Panel: The UIM allows users to adjust temperatures, activate features, and view unit status.
Temperature Adjustment: Temperatures can be adjusted in one-degree increments. Preset temperatures are 45°F (7°C) for the upper zone and 55°F (13°C) for the lower zone in wine storage models. IW-30R storage drawers are preset at 38°F (3°C).
Options Screen: Provides access to various features:
- Activate/deactivate door/drawer alarm.
- Activate accent lighting.
- Activate humidor feature (if applicable).

Wine Storage Racks: Designed to securely hold wine bottles.
Display Rack: A dedicated rack for showcasing specific bottles.
Full-View Glass Door: Allows for easy viewing of the wine collection.
Home Security Connection: For integration with home security systems.
Storage Drawers (model IW-30R): Provide additional refrigerated storage, typically for items requiring a different temperature than wine.
