Description for ICM Controls FS1500L

When it comes to freezing cold temperatures, you can relax knowing ICM's Frost Sentry is on guard. This low-cost, single-set point thermostat is perfect for areas requiring temporary or permanent freeze protection. This easy-to-operate garage thermostat allows you to maintain temperature to your garage/storage area. Attractive, extra-rugged, highly reliable and accurate, this thermostat will look and perform like new for years to come.

Its special foam backing improves accuracy by providing separation from the wall at installation, while sealing up any unsightly wiring holes. This insulated backing helps eliminate the risk of "wall effect" (wall temperature causing false temperature readings).

Ideal for storage areas, garage workshops, crawl spaces, warehouses and other critical areas where protection from extreme cold is essential.

Does the job.

Comments about FS1500L Frost Sentry Garage Thermostat (Horizontal):

I used the Frost Sentry in my heated garage because it allows me to set the thermostat down to 35 degrees, which my other one did not. It works well and does the job with out any fancy features.

Perfect thermostat for your garage

Comments about FS1500L Frost Sentry Garage Thermostat (Horizontal):

The nice thing about this thermostat is that I could keep my garage heater on and above freezing temperatures without breaking the bank. I tried looking around other hardware stores and I could not find one that I could be set at 35 degrees, it's digital, easy to read and simple to hook up.
