A dual-zone installation for personalized comfort
With the possibility of installing two separate indoor units (among the ZE09CB25I, ZE12CB25I, ZE18CB25I or ZE24CB25I models), this heat pump allows you to:
-
Independently heat or cool two rooms or two floors.
-
Adjust the temperature according to the use of each zone.
-
Reduce costs by only heating spaces actually used.
Real-life installation examples : We recently installed a 42,000 BTU Zephyr with an 18,000 + 24,000 BTU configuration in a Boucherville home, where the clients wanted to separately manage the master bedroom and main floor living room. The result: optimal comfort without having to unnecessarily overheat the entire space.
