7. MONITORS – AIR FILTER, SERVICE HUMIDIFIER,
UV LAMP, SERVICE HVAC
The thermostat monitors time and can display scheduled
reminders for the user to service their humidifier, change their
filter and UV lamps, and to remind the user to schedule an
HVAC system maintenance check. All monitors are strictly time
based, so setting a filter monitor to three months will result in
the change reminder being displayed in three months,
regardless of how much the HVAC system has run in that
period. All monitors can also be turned off for installations
where one or more of the components may not be installed.
When the thermostat has verified that a monitor setting has
been reached, a message is displayed on the thermostat (at
the message center location where date and time are normally
displayed) and the label for the multi-function button normally
labeled INFO changes to CALL DEALER.

5. Use ▲ or ▼ button to highlight the amount of time you
wish to set then press the SELECT button. Press the BACK

Important: When an AHC is installed with the thermostat,
either directly or as part of a Model 6504 Intelligent Zone
System, the service humidifier monitor will automatically be
set to AUTO. AUTO is not a choice unless an AHC is present.
Set to AUTO, the AHC will initiate “service humidifier” based
on humidifier type and run time.
