In this option an additional zone is installed into the system serving an unoccupied area such as a stairwell, passage or entry
This zone is left in the closed position and will only open if required by the system
With an iZone system you can select as many dedicated zones as you need.
The benefit of the dedicated electronic constant zone is that all habitable areas can have individual temperature control and if the electronic constant is required to operate it will not affect the comfort of the occupants
The downside of this type of electronic constant is that conditions in the corridor or stairwell may feel mildly uncomfortable while transiting through them and the outlet in this area may generate some noise
