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 temperature 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 tempera-
ture 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.
Should your needs require a
modification of the factory default
settings, refer to “Heat Fast” or
“Cool Fast” instructions on page 31.
