Temporary & Permanent Hold Feature

• Temporary Hold:

Filter Change & Other Reminders 
If your HVAC contractor has configured the thermostat to remind you when the air filter needs changed, you will see a reminder in the display when your air filter needs to be changed.

Resetting The Filter Change Reminder:
When the reminder is displayed, you should change your air filter and reset the reminder by holding down the Set Time/Run Schedule button of the thermostat for 3 seconds.

This thermostat also has other maintenance reminders (Humidity Pad, UV lamp, and IAQ Cell), that are reset with the same procedure.

Keypad Lockout Note:
Keypad lockout provides the option to disable some or all of the buttons on the thermostat. This feature is activated by pressing and holding the buttons for 3 seconds. In this model, the keypad lockout feature has a selectable option to create a custom code for keypad lockout operations. Also, if a code is not created for keypad lockout, this feature will still perform keypad lockout functions without a custom-created code. If a custom keypad lockout code is enabled, the custom created code will need to be entered in order to disable the keypad lockout on the screen. If the custom code is created and the occupant forgets the custom lockout code, the master keypad lockout code will always override any custom created code. The master keypad lockout code is 7761.
