The model TCONT624AS42DAA Comfort Control provides typical operation of a forced air heating and cooling HVAC system. The TCONT624 

comfort control also features a Z-Wave™ module for remote control.

Normally, the Comfort Control displays the Home Screen as shown above.

Clock Display

The current time is displayed in the upper left corner 

of the main screen. The time will blink when the clock 

has not been set.

is connected to Nexia Home Intelligence the clock will 

be updated by the Nexia portal.
