Check each wire connection to verify they are
not shorted or touching together. No bare wire
should stick out from under terminal screws.

persists the manufacturer of your system
or service person can instruct you on how
to test the Heat/Cool system for correct
operation. If the system operates correctly,
replace the thermostat.
Item 2 in the Configuration Menu is the adjustment
that controls the cycle rate. If an acceptable cycle
rate is not achieved using the FA (Fast) or SL

will be incorrect when power is restored. See No
Heat/No Cool/No Fan (common problems) above
for items to check in the system.
See Configuration Menu (Item 4).
Check current clock and program settings including
the AM or PM designations for each time period.
