Forced-air zoning. A TrueZONE system splits one air handler into zones with a damper in each branch duct and a zone panel that opens and closes them on thermostat call. Rectangular dampers are sized to the duct, width by height in inches. When only one small zone calls, a bypass damper relieves the extra static pressure the blower would otherwise push against.

Hydronic zoning. VC zone valves separate the valve body from the actuator, so a failed head can be replaced without draining the loop, and 2-way and 3-way bodies come in sweat and NPT connections. Choose the body by pipe size and Cv, then the actuator by voltage and control type.

Indoor air quality. Media and electronic air cleaners, whole-home humidifiers and dehumidifiers, and ERV/HRV cores are stocked with their replacement filters, pads and parts, matched by model number.

Resideo makes and supports the Honeywell Home line, so many part numbers now carry a Resideo prefix. If an older manual lists a Honeywell number you cannot find, check the Honeywell to Resideo cross-reference.
