Every figure below comes from Wine Guardian's own published data for the DS088. Wine Guardian publishes the ducted split line in a single 208-230 V column, so each capacity rung carries that supply voltage and the condenser inlet air temperature it was measured at.
ModelDS088
SeriesSentinel Series
System typeTwo-piece ducted split: ductable fan-coil plus remote condensing unit
Line frequency60 Hz
Rated cooling capacity9,840 BTU/h at 80°F condenser inlet air, 208-230 V
Recommended cellar volume850 to 4,500 ft³
Storage temperature range55°F to 58°F, per the Wine Guardian Ducted Split product brochure
Serving-temperature optionExtends control to 45°F to 64°F, per Wine Guardian's DS088 product page, which prints this as the All Wine Temperatures Bundle. The Ducted Split product brochure states only the lower bound: with the optional serving temperature the system can cool down to 45°F
Humidity with optional humidifier55% to 65% relative humidity
Temperature control accuracyPlus or minus 1°F, from the Wine Guardian ducted split specifications sheet's own Temperature Accuracy row, which the sheet prints once across all four DS model columns. The Sentinel ducted split manual prints plus or minus 2°F in a Controller Specification shared across more than one product family
Humidity control tolerancePlus or minus 10% RH, with a Wine Guardian humidifier fitted

Minimum circuit ampacity and overcurrent protectionNot published on this page. Take both from the Wine Guardian Ducted Split Specifications Sheet below and have a licensed electrician size the circuit.
Optional electric heatAvailable as a factory option. Take the wattage and its effect on circuit sizing from the Wine Guardian Ducted Split Specifications Sheet below and confirm with a licensed electrician.
Fan-coil fan motor220 W
Condenser fan motor150 W
Fan-coil dimensions (L x W x H)23.81 in x 25.04 in x 19.65 in
Fan-coil weight58 lbs
Condensing unit enclosure (L x W x H)34 in x 12.3 in x 26.07 in
Condensing unit weight96 lbs, the figure printed in the DS088 column of the Wine Guardian ducted split specifications sheet, whose condensing-unit weight row reads 75, 76, 96 and 120 lbs across the DS025, DS050, DS088 and DS200 columns. Wine Guardian also publishes a condensing-unit weight for the DS088 on its own model page that falls below both the smaller DS025 and DS050 units on an identical 34 in x 12.3 in x 26.07 in enclosure, so read this row from the Wine Guardian ducted split specifications sheet and confirm shipping weight with Wine Guardian before booking freight or rigging.

Cabinet constructionAluminum chassis with UL-rated plastic panels, the wording the Wine Guardian ducted split specifications sheet prints once across the DS025, DS050, DS088 and DS200 columns. The Ducted Split product brochure describes the same panels and duct collars as the highest UL rated composite material, making them 5x stronger than before, which is a line-wide statement rather than a DS088 difference
