What warranty does the Honeywell TH5110D come with, and what does it cover?

The TH5110D is covered by a 5-year limited warranty from the date of purchase, covering defects in workmanship or materials under normal use and service (batteries are excluded). If the product is found to be defective during this period, Honeywell will repair or replace it at their option. The warranty does not cover removal or reinstallation costs. (Page 14)
