Pressing the min/max button displays the minimum and maximum temperature and humidity readings reached since the last time the memory was manually reset.  The La Crosse Technology WS-9023U-IT may be set to display temperatures in °F, in which case the clock will be displayed in 12 hour format, or °C, in which case the clock will be displayed in 24 hour format. Display digits are about 3/8" high. 

The distance from the remote to the display can be up to 330 feet with no obstructions.  Passing through an exterior wall will reduce range about 20 feet, each interior wall will reduce range about 10 feet.  Results will vary depending on building construction and the possible presence of interference.
