Zone One
The perfect solution for over-heating and over-cooling problems

Zone one from Jackson Systems


A typical heating and cooling system has one controlling thermostat, limiting the ability to control setpoint based on its physical location. In applications where the HVAC equipment is used to provide conditioned air to multiple spaces, changes in both internal and external loads from one space to another can pose over-heating or over-cooling problems. The Zone One System uses pressure independent dampers or diffusers combined with individual space thermostats to manage occupant comfort based on individual setpoint preferences.​
