Recovery
The time when the thermostat operates the heating or
air conditioning equipment to return the zone from the
energy saving temperature to the comfort temperature.
The thermostat starts the recovery period early so the
zone will be at the comfort setting by the time you've
chosen.
Setback
Reducing the temperature in the zone for a set period
every day in winter for energy savings. The lower
temperature is the energy saving temperature.
Setup
Raising the temperature in the zone for a set period
every day in summer for energy savings. The higher
temperature is the energy saving temperature.
Setpoint
The thermostat temperature setting you select. The
thermostat turns the heating or cooling equipment on and
off to maintain this temperature at the thermostat location
until another temperature setting (setpoint) goes into
effect.
SYSTEM light
This light glows whenever the thermostat is calling for
heating or air conditioning.
Time period
One of four program periods available with the
thermostat. One period begins when the previous
program period ends.
