Glossary
Anticipators
Used to anticipate the drop or rise in temperature and energize the appropriate
system before reaching the set point. Anticipators affect how tightly the setpoint
temperature is maintained.
Auto Dead Band
Sets the minimum separation in auto mode between heat and cool setpoints
(with dual setpoints) or maximum drift before system latches alternate mode
(with single setpoint).
Balance Point
At low outdoor temperatures, the refrigeration cycle of a heat pump is not able
to supply the heating requirements without the aid of a supplementary heat
source. At higher outdoor temperatures, it is inefficient to use supplementary
heat.
The heat pump balance point sets the minimum outdoor temperature required to
allow operation of the heat pump. Additionally, for conventional heat pump
system types (Heat/Cool Type setup parameter = HP), the Aux-Heat Balance
Point sets the maximum outdoor temperature to allow operation of the auxiliary
heat.
Since dual fuel system types only allow operation of one system at a time, only
one balance point is available.
Blower (Fan)
An air-handling device for moving air in a distribution system.
Call
A call is the action taken by the thermostat when it sends a signal to turn on the
heating or cooling system.
Dual Fuel
A heat pump used in conjunction with an existing fossil fueled furnace.
Emergency Heat (Supplementary Electric Heat)
The auxiliary (AUX) or emergency heat provided at temperatures below a heat
pump’s balance point. It is usually electrical resistance heat.
Extended Cool
Extends the cool setpoint range to the full auto range of 38 to 99° F.
Forced Air
A type of heating system that uses a blower motor to move air through the
furnace and into the ductwork.
Furnace
Equipment used to convert heating energy, such as fuel, oil, gas or electricity, to
usable heat. It usually contains a heat exchanger, a blower and the controls to
operate the system.
Heat Pump
A unit that both cools and heats. A heat pump system can be either a split
system or a packaged system. A heat pump can be used in conjunction with a
gas/oil/LP furnace (using the furnace instead of electric resistance heat when
temperatures fall below about 35º F).
