ABOUT TWO STAGE UNITS...

Two stage systems have two "speeds" of heating and cooling.  

"Stage 1" is similar to "low speed" and "stage 2" is similar to "high
speed".  In most cases, stage 1 is sufficient to heat or cool the
building, but from time to time, due to hot or cold weather, stage 2 is
needed to keep the building comfortable. 

This thermostat will control both stages of heating or cooling as
needed to meet the heating and cooling needs of the building.  It is
usually preferable to use stage 1 only, since it is the most efficient
mode of operation for the heating and cooling equipment.  Stage 2
should be used only when necessary. 
 

ENERGY EFFICIENT CONTROL

Using the programmable or remote control features of your
thermostat, you can save energy costs by setting back the thermostat
during unoccupied times.  This reduces the energy loss from  indoors
to outdoors.  When recovering from the set back, (heating or cooling
the building to a comfortable temperature after being at an energy
saving temperature) the thermostat will use the most energy efficient
mode of the heating and cooling equipment, as long as it can heat or
cool at an acceptable rate. 

This thermostat has microprocessor intelligence that continually
monitors the performance of the system and uses stage 2 only when
necessary.  If it determines that stage 1 is able to heat or cool at a rate
of 5 degrees per hour or better, stage 2 will not be used.  If stage 1 is
unable to heat or cool at this rate, the thermostat will use stage 2 as
needed.  Under these conditions, stage 1 will run continuously and
stage 2 will cycle on and off as needed.
