Maintenance Reminders - Honeywell Home THX321WF2001W User Manual

IAQ REMINDERS
You can set up IAQ reminders in the thermostat to remind users when filters, pads, UV bulbs, etc. need cleaning or replacement.
The available reminders vary based on the ISU settings. For example, if the thermostat is configured to control a flow through
humidifier, it will have the humidifier pad reminder but not the humidifier tank reminder:
• Air Filter 1
• Air Filter 2
• Electronic Air Cleaner Pre-Filter
• Electronic Air Cleaner Post-Filter
• Humidifier Tank / Water Filter
• Humidifier Pad
• Dehumidifier Filter
• Ventilator Core
• Ventilator Filter
• UV Bulb 1
• UV Bulb 2
Reminders that are displayed under preferences will change based on the IAQ equipment installed. Reminders for equipment
that is already set up can be set using the steps below. Reminders for IAQ equipment that is not yet set up must be turned on
from the installer setup.
If you want to disable the alert, go MENU-PREFERENCES-REMINDERS to turn reminder off.
NOTE: Air Filter, Humidifier Pad, Dehumidifier Filter, and Ventilator Filter are displayed under Preferences even if they have not
been set up. Humidifier Pad is not displayed if a steam humidifier has been installed.
To access or adjust the reminder settings
1. Touch any part of the display to wake the thermostat.
2. Touch the MENU icon at the bottom of the screen.
3. Scroll down and select "preferences."
4. Select the reminder you want to set from the list (shown above).
5. Press ^ or v to set the timer length. Ranges, increments, and units will change based on the reminder.
6. Press Done to save the reminder.
7. Press Reset Timer when you have completed the recommended maintenance or you can extend the timer setting to turn off
the alert and remind you later to do the recommended maintenance.
• Repeat these steps for all reminders you want to set
NOTE: When set for run time days, the thermostat tracks the amount of time the fan has run and compares that time against the
number of run time days selected. Fan run time is counted when there is a call for forced air heating, cooling, or fan.
Dehum setting range: 25% RH to 80% RH.
Models made prior to October 2019 had a minimum of 40% RH but if connected to Wi Fi and registered to Resideo App the
minimum setting is automatically updated to 25% RH. This would not affect any range stop settings.
