Same Great Product.

Simpliﬁed User Interface.

Honeywell is making a running change to the user interface of our TrueSTEAM™ Humidiﬁcation Systems to provide additional clarity

on the actions required to service and clean the unit. You’ll be able to easily identify which model you’re working with by locating the

date code on the TrueSTEAM box or on the unit itself located behind the right side handle. Here’s what you need to know about the

user interface to install, service and clean Honeywell TrueSTEAM.
