CORRECTIVE ACTION
Digital thermostats normally provide precise
temperature control and may cycle faster than some
older mechanical models. A faster cycle rate means
the unit turns on or off more frequently but runs for
a shorter time so there is no increase in energy use.
If you would like to increase the cycle time, refer to
the Installation Instructions under Installer Table for
settings. If an acceptable cycle rate is not achieved
by the adjustment in the Installer Table then you
may want to contact a local heating and air condi-
tioning service person for further suggestions.
The cycle rate for cooling is fixed and can not be
adjusted. Contact a local service person for sugges-
tions.
