FAQ Frequently Asked Questions About the TTW02B Sentinel What size wine cellar does the Wine Guardian TTW02B Sentinel cool? The TTW02B Sentinel delivers a nominal 2,650 BTU/h at 75°F, sized for mid-sized residential and commercial wine cellars and displays. Because cooling load depends on insulation, glass exposure, and ambient temperature, confirm the right capacity with Wine Guardian's sizing calculator and a qualified professional before purchase. Does the Wine Guardian TTW02B Sentinel control humidity? Yes. The TTW02B Sentinel includes a built-in humidity sensor that combines a thermostat and humidistat. Paired with an optional Wine Guardian freestanding humidifier, it helps maintain roughly 55%-65% relative humidity for proper long-term wine storage. How do I install a Wine Guardian through-the-wall cooling unit? The TTW02B Sentinel is designed for do-it-yourself installation between standard wall studs, using the included mounting bracket or a wall sleeve.

Final placement, electrical, and ventilation requirements should be confirmed with Wine Guardian's documentation and a licensed professional. How quiet is the Wine Guardian TTW02B Sentinel?
