Glossary of Key Terms (continued)
Line Voltage Baseboard Heat
A system in which a special line voltage capable thermostat switches a baseboard electric heating element on or off based
on the current room temperature and set point.
Millivolt Heat Only
A heating system usually implementing gas fired wall or floor heaters to heat the space. The system requires two wires for
the special millivolt capable thermostat or a standard/non-electric heat-only thermostat. It has no connection to any sort of
AC power source. The small electrical voltage is produced by using the flame from the pilot light.
Packaged Units
Usually an outdoor installed air handler which has built-in heating or cooling elements. These elements generate the warm or
cool air and air is moved into the space via the duct work.
Split System Air Conditioner
An air conditioning system which has two to five pieces including an outdoor mounted condenser and interior evaporator
units. A separate piece, called the air handler, moves the air through the space via the duct work.
Stage
A level of operation for a piece of HVAC equipment. A stage can be for cooling or heating. Single stage means that there is
one level of output when performing the cooling or heating stage. To improve efficiency, multi-stage systems use low and
high levels as separate stages. When it is desirable to reach the desired temperature faster, a higher level or second stage
will be triggered and efficiency will be lost compared to using the lower level or first stage.
Temperature Averaging
A process by which a thermostat can receive multiple temperature readings from various temperature sensors within a
specific space or zone. The thermostat averages the temperature readings which allows for a more even temperature in the
zone. This provides balance by helping to prevent one room from being hotter than another room in the same zone.
Zone
To improve the efficiency of a system, the entire home is often split into smaller segments called zones. Zones are separate
areas of the house which are managed by the same thermostat. When a zone requires heating or cooling, that part of the
system can turn on without running the entire system for the rest of the house. Some systems may have one zone per floor
and others may have one zone per room.
