Four-Zone System
LZP-4
Designed to control
multistage heating and
cooling systems

Lennox’ LZP-4 zoning system enhances your comfort by allowing you to
control the flow of heated and cooled air through different areas of your home.
Say you have an upstairs floor that’s always too hot. With the LZP-4, you can
reduce heating in that area. And if you have a room that gets a lot of use
throughout the day, you can make sure it gets extra air conditioning.
The LZP-4 zoning system meets your specific comfort needs in one zone,
without affecting the other zones. It’s like having a heating and cooling
system for each living area in your home. This not only maximizes your
comfort—it also saves you money, year after year.
