Answer:

Designer Wine Storage (IW) units connect to home security systems using low-voltage leads to chime an alarm if temperatures are too cold or too warm based on the setpoint.

• If the electronic control detects a wine zone that is 10°F (6°C) warmer than the setpoint temperature threshold or 5°F (3°C) colder than the setpoint temperature threshold for an extended period of time, the alarm sounds.
• The home security system company typically connects products to the alarm system. See also, Wine Storage Temperature Alarm Connected to Home Alarm System.
• If the warm temperature threshold is reached:
  • Error code appears
  • Light relays are disabled
  • Alarm relay is enabled
  • If the alarm key has been pressed, alarm chimes
• If the cold temperature threshold is reached:
  • Error code appears
  • Compressor is disabled
  • Refrigerant valve is disabled
  • Evaporator fans are disabled
  • Alarm relay is enabled
  • If the alarm key has been pressed, alarm chimes

1. Find two connectors behind the top trim.
2. Provide 10' (3 m) minimum lead wires for each connector, exiting the back wall near the electrical receptacle.
3. Remove the top trim by disengaging the trim from the hinge side of the unit.
4. Rotate the trim and remove the trim pin from the handle side vertical support.
5. Use spade terminals or wire nuts to make proper wiring connections. Refer to the following color codes:
   • Normally open contacts - white with red stripe wire
   • Normally closed contacts - white with blue stripe wire
   • Common - gray with white stripe wire

1. Allow one zone in the unit to reach set temperature of 40°F (4°C).
2. Once set temperature is reached, change the setpoint to 65°F (18°C) and wait 30 minutes.
3. All other zones should have setpoints at the highest value to help speed up the testing procedure.
