Second Stage Time Delay Second Stage Time Delay Second Stage Time Delay Second Stage Time Delay Second Stage Time Delay
Your thermostat is designed to determine the optimum time to
activate the second stage. Simply raising the temperature in
heating or lowering it in cooling will not always force the
thermostat to bring the second stage on quickly. There is a time
delay from 0-30 minutes depending on the performance of the
first stage of the system.
EXAMPLE: For the last 2 hours the thermostat is set on 70° and
the room temperature is 70° with the equipment using only the
first stage of heat. Since the equipment is keeping the tempera-
ture within 1 degree of setpoint, the thermostat will delay
second stage for a longer time if you manually raise the
temperature or if the room temperature quickly changes. Once
the second stage comes on, it will come on sooner the next time
there is a difference between the setpoint and the room
temperature. The net effect of the staging program is that when
the first stage is capable of making temperature the second
stage will delay longer. When the thermostat calculates that
first stage cannot make temperature in a reasonable time, the
second stage will come on sooner. This built in function
automatically optimizes the use of additional stages of heat or
cool.

This section will help you plan your thermostat's program to
meet your needs. For maximum comfort and efficiency, keep
the following guidelines in mind when planning your program.
• When heating (cooling) your building, program the temper-
atures to be cooler (warmer) when the building is vacant or
during periods of low activity.
• During early morning hours, the need for cooling is usually
minimal.

Look at the factory preprogrammed times and temperatures
shown in the sample schedule. If this program will suit your
needs, simply press the RUN button to begin running the
factory preset program.
If you want to change the preprogrammed times and tempera-
tures, follow these steps.
Determine the time periods and temperatures for your pro-
gram. You must program four periods for each day. However,
you may use the same heating and cooling temperatures for
consecutive time periods. You can choose start times, heating
temperatures, and cooling temperatures independently (for
example, you may select 5:00 AM and 70° as the weekday 1st
period heating start time and temperature and also choose period heating period heating period heating period heating
7:00 AM and 76° as the weekday 1st period cooling
and temperature).
Use the table to plan your program time periods and the
temperatures you want during each period. Fill in the complete
table to have a record of your programs.
