MULTI-ZONE APPLICATIONS

New hyper-heating multi-zone units allow you to create an oasis of comfort throughout your entire home

in the rooms you use most, any time of the year.

Each room (zone) operates independently with it's

own wireless or wired remote control, so people in

different rooms can choose the temperature

that makes them most comfortable.
