Wine Guardian TTW01B Sentinel Through-The-Wall Wine Cellar Cooling Unit
Self-contained through-the-wall unit for small wine rooms and displays: 1,440 BTU/h at 75°F, 120 V plug-in, humidity sensor built in
- The TTW01B delivers 1,440 BTU/h at 75°F condenser air and 830 BTU/h at 125°F.
- The TTW01B Sentinel exhausts its heat from the condenser end into the room on the other side of the wall, and that air can be 20°F warmer than the air entering it.
- Buy the Sentinel if you want a humidity sensor and a humidifier connection as well as temperature control, and the Classic if temperature control alone is enough.
- The unit needs a dedicated 120 V circuit and an outlet within 5 ft, outside the cellar, connected by a licensed electrician.
- The TTW01B Sentinel is rated at 49.5 dBA on the cellar side, measured six feet from the supply air grille.

The Wine Guardian TTW01B Sentinel is a self-contained through-the-wall wine cellar cooling unit rated at 1,440 BTU/h at 75°F condenser air, with a built-in humidity sensor and internal condensate re-evaporation. It is designed to fit between standard wall studs: cooling coil and fan face the cellar, and the condenser releases the heat into the room on the other side of the wall. It runs on a 120 V plug, needs no ductwork and no remote condenser, and is rated for interior walls only. It is one of the Wine Guardian through-the-wall units, and we sell it as an authorized Wine Guardian dealer.

Who the TTW01B Sentinel is for
The TTW01B Sentinel covers cellars up to about 600 cubic feet. Wine Guardian sizes the Through-the-Wall B series by heat load rather than by a published cubic-foot rating, so this figure is calculated with Wine Guardian's own cooling calculator at a documented baseline: an 8-foot ceiling, no glass, R-13 walls and floor, R-29 ceiling, a 75°F warmest wall, 80°F air to the condenser and a 55°F cellar. Wine Guardian separately lists the TTW01B as the replacement for the TTW009, which it rates at 50 to 600 cubic feet.
The TTW01B Sentinel is the right choice for a small wine room, closet or display behind an interior wall, where the heat load fits 1,440 BTU/h and humidity should be read as well as temperature.
Best for
- Small cellars and wine displays whose heat-load calculation fits 1,440 BTU/h at 75°F
- An interior wall with a room behind it that can take the warm condenser air
- Owners who want a humidity reading and the option to connect a Wine Guardian freestanding humidifier
- Replacing a TTW009, which Wine Guardian names the TTW01B Sentinel as the successor to
Choose another model when
- The unit has to go through an exterior wall or the cellar needs heat: the TTW01B Defender
- Temperature control alone is enough: the TTW01B Classic
- The heat load is above what 1,440 BTU/h covers: the TTW02B Sentinel

Frequently asked questions
TTW01B Sentinel Through-The-Wall questions
Should I buy the Wine Guardian TTW01B Sentinel or the TTW01B Classic?
Buy the Sentinel if you want a humidity sensor and a humidifier connection as well as temperature control, and the Classic if temperature control alone is enough. Both are rated at 1,440 BTU/h at 75°F. The Sentinel also re-evaporates its condensate inside the unit, while the Classic needs a drain line, and it runs at 49.5 dBA against the Classic's 51.9 dBA.
Is the Wine Guardian TTW01B Sentinel big enough for my wine closet or small cellar?
It is big enough when the cellar's heat load fits 1,440 BTU/h at 75°F condenser air. Wine Guardian sizes the Through-the-Wall B series by heat load, so glass, insulation and the room behind the wall decide the answer. At 90°F condenser air the TTW01B gives 1,070 BTU/h and at 125°F 830 BTU/h. Compare the cooling units for cellars up to 1,200 cubic feet if the load is higher.
Where does the Wine Guardian TTW01B Sentinel exhaust its heat?
The TTW01B Sentinel exhausts its heat from the condenser end into the room on the other side of the wall, and that air can be 20°F warmer than the air entering it. The Sentinel is not rated for an exterior wall, so it goes through an interior wall. Wine Guardian offers an optional duct collar kit for carrying the warm air away, and a mechanical room next door makes ducting easier.
How quiet is the Wine Guardian TTW01B Sentinel?
The TTW01B Sentinel is rated at 49.5 dBA on the cellar side, measured six feet from the supply air grille. The condenser side, which faces the room behind the wall, is rated at 53 dBA at six feet. The Sentinel carries internal sound insulation, and it is quieter than the TTW01B Classic at 51.9 dBA and louder than the TTW01B Defender at 47.9 dBA.
What warranty comes with the Wine Guardian TTW01B Sentinel?
Wine Guardian's Standard Warranty covers the TTW01B Sentinel for 25 months on parts and 13 months on labor from the date of original invoice. Labor is reimbursed only when a Wine Guardian representative authorizes it before work starts. Warranty service runs through Wine Guardian, which manufactures the unit.
Does the Wine Guardian TTW01B Sentinel control humidity?
The TTW01B Sentinel reads humidity with its combined temperature and humidity sensor, and it adds moisture only with an optional Wine Guardian freestanding humidifier connected to it. The controller then runs temperature and humidity together. The default humidity set point is 30% RH and is changed in the app. Humidifier control works between 35°F and 75°F in the cellar.
Does the Wine Guardian TTW01B Sentinel need a drain line?
No drain line is needed as shipped: the Sentinel re-evaporates its condensate inside the unit, and its drain tube comes plugged. Wine Guardian recommends an external drain with a humidifier or in high-humidity rooms. A condensate overflow alarm shows when one is needed. The field drain kit has 6 ft of clear tubing and a barbed fitting and runs to a floor drain or condensate pump.
What should I check if a through-the-wall unit leaks water?
Check the humidity load and the leveling first. A leaking through-the-wall unit is a service question owners send us about this line. Wine Guardian's manual and brochure point to three causes: more condensate than the unit can re-evaporate, from high humidity, a humidifier or a weak vapor barrier; a unit that is not level; and a blocked or plugged drain tube. Its fix for the first is an external drain line.
Which Wine Guardian model replaces the TTW009?
Wine Guardian states on its TTW009 page that the unit is being replaced with the TTW01B Sentinel. Both are self-contained through-the-wall units for an opening of up to 14½ in by 16¼ in, stud to stud. The TTW01B Sentinel chassis is 27.6 in long against the TTW009's 25 in, so check the depth on both sides of the wall. It adds a humidity sensor, condensate re-evaporation and Bluetooth and NFC controls.
What does installation of the TTW01B Sentinel involve?
Installation means cutting an opening of up to 14½ in by 16¼ in between the studs of an interior wall, fastening the EasyMount sleeve to the studs, sliding the unit in and sealing the joint. The unit needs a dedicated 120 V circuit and an outlet within 5 ft, outside the cellar, connected by a licensed electrician. Wine Guardian's manual calls for qualified personnel familiar with local codes.
