TROUBLESHOOTING
(Troubleshooting continued on next page)
Resetting the Thermostat or Thermostat Settings
If the thermostat has good batteries, but has a blank display or does not respond to key
presses, the thermostat should be reset by removing the batteries for
2
minutes. This reset
will not change the menu settings or program. If the condition persists after reinstalling the
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.

Cycles Too Fast or
Slow (narrow or
wide temperature
swing)
The location of the thermostat
and/or the size of the Heating
System may be influencing the
cycle rate
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.
