Zone Control
Problem:
Most two-story homes have an 8-12 degree difference in temperature between
upstairs and downstairs. Most ranch-style homes have an 8-12 degree difference
in temperature between one end of the home and the other. A home with this
problem is NOT a comfortable place to live.
Solution:
Zone control! Zoning is a relatively easy way to improve overall space comfort
and lower operating costs. With zoning – a single heating and cooling system can
be enhanced to provide more precise comfort control throughout an entire home.
Zone control components:
- Zone Panel – The brain of the system, the zone panel
connects directly to the heating/cooling equipment and interprets commands
from the thermostats in the different zones of the home. The zone panel calls
for heating or cooling and controls the opening and closing of zone dampers.
- Thermostats – these controls reside in the different
zones of the home and send commands to the zone panel to call for heating or
cooling when there is a change in zone temperature. Most modern zone control
systems are able to incorporate standard, non-proprietary thermostats.
- Dampers – dampers are installed inline within a homes
ductwork. The dampers in a zoned system open and close to allow more or less
heated or cooled air into their zones. Dampers are typically configured as
normally open – powered closed, but can also be set up to open when powered.
Most dampers require 24VAC from the zone panel to close or open.
