The Honeywell TH6220U2000/U thermostat, part of the T6 Pro series, offers flexible power options:

• Hardwired (24V AC): Ideal for a permanent installation, this method powers the thermostat through your HVAC system's common wire (C-wire)

• Battery-Powered: If a C-wire isn't available, the thermostat can operate using two AA batteries. This setup is convenient for installations without direct access to a C-wire

Requires two AA batteries and features a low battery warning indicator to alert you when replacements are needed. For optimal performance, Honeywell recommends replacing the batteries annually or before extended periods away from home. TH6220U2000/U can function either hardwired or with batteries, providing versatility to accommodate various installation scenarios.
