Backup Battery - A battery located in the T7200/
T7300 thermostat that provides electricity to
maintain your time and temperature schedule
during power loss. If the battery is dead or runs
down during a power failure, the time and tempera-
ture schedule will be lost. However, the thermostat
will control to a standard set of "default" setpoints
when power is restored.
Default Setpoints - Temperature settings of 68 F
for heating and 78 F for cooling that are built into
the T7200/T7300. These assure that the system will
remain operational even if the thermostat is not
programmed or the time and temperature schedules
are lost due to battery failure.
Intelligent Recovery'" - A control method which
adjusts the heating warmup and cooldown
time periods based on outside weather conditions.
Commonly referred to as "optimized start."
Mechanical Cooling - Cooling that is orovided bv
running compressors to extract heat from the
conditioned space.
Minimum Operation Times - Fixed minimum on/off
equipment run times used to prevent harmful short
cycling (turning on and off too often) which can
significantly reduce equipment life or cause
permanent damage.
Economizer - An auxiliary control system which
allows use of cool outdoor air for free cooling, in
place of electrical air conditioning equipment. Based
on the availability of outdoor air for "free" cooling!
the economizer control system will provide Cool air,
increasing comfort without the extra expense of
running mechanical cooling. Only if outdoor air
cannot or does not sufficiently cool the space will
mechanical cooling be allowed to run.
"Free" Cooling - See Economizer.
Occupied Temperature Setpoint - The heating and
cooling temperature settings used when the room
or building is scheduled to be occupied.
Occupied Start Time - The selected time at which
the air conditioned space is to reach the comfort
temperature for people occupying the room.
Setpoint - The selected temperature at which the
heating/cooling system is to maintain the condi-
tioned space. There are separate setpoints for
heating and cooling in the OCCUPIED and
UNOCCUPIED time periods.
