Don't loose an entire freezer full of food in the unfortunate event of a freezer failure. Whether it's the freezer in your kitchen or the one you have in the garage, the INSTEON I/O Linc Freezer Failure Sensor Kit can send an INSTEON signal to your home network to notify you of the concern as soon as the temperature in your icebox reaches above 39 F. In addition to wasted food, a failing freezer can have ice buildup inside that can quickly turn to water when the temperature inside rises, possibly causing damage to your floor if the water were to leak. As part of your INSTEON home automation network, this kit will act as an early alert system, triggering lights or appliances to turn on in the event that your freezer fails.How it Works Simply place the temperature sensor in your freezer and it will identify when the internal temperature goes above 39 F. Once that happens, the contact switch inside the sensor will send a signal to I/O Linc via the included connector wire. The I/O Linc can then be linked on any INSTEON controlled device, letting you know the moment there is a problem.
