batteries, replace the thermostat.
To conveniently reset only the schedule and user settings back to factory defaults, press Menu
and Backlight buttons at the same time and hold until the display goes blank and resets.

Corrective Action
Verify thermostat and system wires are securely
attached.
Diagnostic: Set System Switch to Cool and lower
setpoint below room temperature. Same procedures
as diagnostic for "No Heat" condition except set the
thermostat to Cool and lower the setpoint below the
room temperature. There may be up to a five minute
delay before the thermostat clicks in Cooling if the
compressor lock-out option is selected in the installer
menu. (see INSTALLER MENU, item 50)
Check each wire connection to verify they are not
shorted or touching other wires. Try resetting the
thermostat. If the condition persists contact your
HVAC service person.
Display can be adjusted +/-5°. See User Menu item

Digital thermostats provide precise control and cycle
faster than older mechanical models. The system
turns on and off more frequently but runs for a shorter
time. If you would like to increase cycle time, choose
SLO for slow cycle in the Installer menu. (Reference
menu items 30 & 35) If an acceptable cycle rate is not
achieved, contact your HVAC service person.
1.) See corrective action for "No Heat"
2.) See corrective action for "No Cool"
3.) Replace thermostat
4.) Make sure keypad lockout is not turned on
