TheHoneywellTrueDRYDH65ensuresthehomeismaintainedatproperhumiditylevelsthroughitshighperformance
and efficiency.
Benefits
• Removesupto65pintsofwaterfromtheindoorair.
• Built-inhumiditycontrolrequiresnoadditionalwiringtoanexternalcontrol.
Justpluginandgo!Choiceofexternalcontroloptionsalsoavailablefor
centrally ducted control.
• Feedbackonoperationandmaintenanceprovidedviaintuitiveon-board
LED light interface.
Maintaining Ideal Humidity
Dewpointsandrelativehumidity(RH)affectthewayyourbodysensesheat.
Higher humidity levels cause the air to feel much hotter than the actual temper-
ature.Whenmaintainedproperly,yourcoolingequipmentmaynotrunasmuch
because dehumidified air feels cooler in the summer.
About the TrueDRY DH65 Dehumidifier
Idealhumidityisdefinedbyindustry
experts*asbeingbetween40-60%onan
average annual basis. When indoor humidi-
tyexceeds60%,thehomeismoresuscep-
tibletomoldandmildewgrowth.TrueDRY
DH65safeguardsagainstexcessivehumid-
ity in the home year-round.
