How do I bypass the schedule on the TH4210D, TH4110D, TH4110B thermostat?

Press up or down to immediately adjust the temperature. This will temporarily override the temperature setting for the current time period.  “Temporary” will appear on the display.  The new temperature will be used until the next period begins.

To permanently ignore the schedule, press up or down until the desired temperature is displayed. Then, press the Hold button to maintain the new temperature indefinitely. The word Hold will appear on the screen. 

Press the Run button if you wish to cancel either override and resume the schedule. The word Hold will disappear and the thermostat will be set to the temperature programmed for the current period.
