Honeywell does not document a means of executing a factory reset. Consider the troubleshooting tips at https://www.manualslib.com/manual/1145322/Honeywell-Rthl2510.html?page=17&term=reset&selected=3. Otherwise (or if you require further explanation), you'll have to consult Honeywell: use the contact information here--https://www.contacthelp.com/honeywell/customer-service.
