CONTACT INFORMATION
This allows the servicing HVAC contractor to put their name and phone number into the thermostat to
remind you when service may be required.
SERVICE MONITOR MENU
Two menus are available, the Service Monitor and the Filter Monitor. Both can be set based on the
HVAC system run time or the calendar. See Reminder Interval.
The Service Monitor can be set from OFF to 360 days in 30 day increments or OFF to 980 in 20
hour increments.
The Filter Monitor can be set from OFF to 360 days in 30 day increments or OFF to 980 in 20
hour increments.
REMINDER INTERVAL
The Reminder Interval can be set for either HVAC system run time or based on the calendar.
If Run Time is chosen, the service reminder will be set in hours. After the HVAC system has been
operating for the selected number of hours, a Service Reminder will be displayed informing you that
service is suggested for your system.
If Calendar Time is chosen, the service reminders will be set in days. After the selected number of
days has passed, a Service Reminder will be displayed informing you that service is suggested for
your system.
When would I need to change the INSTALLER settings?
NEVER! The INSTALLER SETTINGS are selected based on the type of equipment you have in your home. This feature should be
set only by a certified HVAC technician. Changing these settings could result in higher energy costs and may even damage your
equipment. You should only change the FILTER MONITOR length should you get a new type of filter.
