The display reads in Fahrenheit or Celsius, and the LED cooling and power indicators tell you what the unit is doing even in a pitch-black crawlspace. Electrically it is rated 120VAC 60Hz, 8.3A and 1000W max, and it is ETL…

Frequently Asked Questions

Can I use this to control a heater or a heat mat?

No. BN-LINK specifies this temperature switch for cooling devices only - it energizes the outlet as the temperature rises, so heating loads fall outside its design.

How large a fan can it run?

It is rated for 120VAC 60Hz with a maximum load of 8.3A / 1000W. Add up the nameplate amps of whatever you plug in and stay under 8.3A.

What temperature range can I set, and does it show Celsius?

The control range is 40-108F, set with the three-button interface, and the digital display supports both Fahrenheit and Celsius units.

How far from the outlet can the sensor sit?

The temperature probe lead is 4.92 ft and the power cord is 3.94 ft, so the probe can sit roughly nine feet from the wall receptacle.

Is it safety certified, and what warranty comes with it?

It is ETL listed and rated 120VAC 60Hz, 8.3A / 1000W. For current warranty terms, check the product listing or contact BN-LINK directly.
