8. BLOWER EXTENSION FOR HUMIDITY CONTROL
If the heating equipment has not run long enough to allow the
humidifier to meet the humidity demand, the thermostat will
continue the blower after a heat call. One second before the
thermostat turns off the heating terminal(s), the fan terminal
will be energized thus extending blower operation. If the fan
terminal was on as part of the heat call it will remain on, if it
was not on it will be turned on. The thermostat will operate
the blower for no less than 5 minutes after the heat call and
not more than 15 minutes. This will allow the humidifier to
continue to put moisture in the air to satisfy the humidity
demand. This feature can be enabled or disabled and can only
be used when an ADHC is part of the installation.
Note: To take full advantage of this feature, the humidifier
must be plumbed to hot water.
To enable blower extension:
1. Make sure the thermostat is in the OFF mode.
2. Press and hold both the ▲ and ▼ buttons for 3 seconds.
– The display will show the ADV. SETTINGS MENU.
3. Use the ▲ or ▼ button to highlight
“
BLOWER EXTENSION”
and press the SELECT button.
4. To cancel, press the BACK button
5. To change whether Blower Extension is enabled (on) or
disabled (off), press the ▲ or ▼ button to highlight either
ON or OFF.
6. To finish and return to the ADV. SETTINGS MENU, press
the SELECT button.
9. 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.
To set humidifier, filter, UV and HVAC service
reminder schedules:
1. Press the MENU button.
2. Use ▲ or ▼ button to highlight SETTINGS, then press the
SELECT button. Press the BACK button to cancel.
3. Use ▲ or ▼ button to highlight MONITORS, then press
SELECT. Press BACK to cancel.
4. Use ▲ or ▼ button to highlight the monitor you wish to
set (AIR FILTER, SERVICE HUMIDIFIER, UV LAMP or
SERVICE HVAC) then press the SELECT button. Press the
BACK button to cancel.
5. Use ▲ or ▼ button to highlight the amount of time you
wish to set then press the SELECT button. Press the BACK
button to cancel.
6. Pressing the SELECT button, after setting the schedule,
takes you back to the MONITORS screen.
• To set additional reminder schedules return to step 3.
• To finish, press the BACK button three times to return to
normal operation.
To reset an active monitor:
1. Press the CALL DEALER button.
2. Press the RESET button.
3. This will reset the monitor and return you to the Main Screen.
Important: When an ADHC is installed with the thermostat,
either directly or as part of a Model 6504 Intelligent Zoned
Comfort System, the service humidifier monitor will
automatically be set to AUTO. AUTO is not a choice unless an
ADHC is present. Set to AUTO, the ADHC will initiate “service
humidifier” based on humidifier type and run time.
