Auto-Setback and Auto-Off Features
The HW 50 system comes standard with Auto-Setback and Auto-Off Features. These are pre-
programmed for 30 minute Setback and 30 minute Auto Off, which can be turned off by the switch on
the back of the unit. When Setback mode has been entered, the heat level will be adjusted to 3.5.
