How do I set a temporary hold temperature setting on a Honeywell RTH221 Thermostat?

Program schedule override (temporary)

Press ▲ or ▼ to immediately adjust the temperature. This will temporarily override the temperature setting for the current time period.

“Temporary” will appear on the display and the current program period will flash.

The new temperature will be maintained only until the next programmed time period begins.

To cancel the temporary setting at any time, press RUN.

NOTE: Make sure the thermostat is set to the system you want to control (heat or cool).
