Troubleshooting Guide • Homeowner Manual
Second, Third and/or Fourth Stage Won’t Come On
Possible Cause
Corrective Action
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.
Wait for the second, third and/or fourth stage to
come on.
