Thermostat Quick Reference

Caution: When the battery ic on appears replace your AA batteries immediately. Failure to do so may result in your heating & cooling system becoming inoperable. Freezing or overheating can occur.

Important: 
The low battery icon is displayed when the AA battery power is low. Whenever the thermostat detects low battery voltage from the AA batteries, the low battery icon will begin flashing on the screen for 21 days (if the batteries are not changed). If the batteries are not changed 22 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until buttons are pressed. If the batteries are not changed 43 days after the thermostat detects low battery voltage, the thermostat screen will only show the flashing battery icon until buttons are pressed and the setpoints will offset to 85°F/29°C in cooling and 55°F/13°C in heating. At this stage, set point changes can be made temporarily, but the setpoints will change back to defaulted values after a 4-hour period. The thermostat will continue to perform this low battery flashing, temperature offset condition until the internal voltage threshold is reached. When the thermostat internal voltage threshold is reached, all relays will be opened and the thermostat will become inoperable until new batteries are installed.

Setting the Humidity

Setting Target Humidity Setpoint 
Follow the steps below to change your target humidity setpoint. Press the HUMIDITY key. Use the key to select the target humidity setpoint. Press DONE when completed.

Setting Target Humidity Setpoint
Ambient humidity will flash in the time field when Humidify or De-Humidify is set to ON. HON will also flash when the Humidity terminal is energized. dON will also flash when the De-Humidify terminal is energized.

Note: The target humidity setpoint is not programmable. Unlike temperature, humidity does not change quickly and should not be programmed.
Humidity is only energized during heat. Dehumidify is only energized during cool. Heat and Cool each have their own target setpoints.

Recommended Heating Settings:

A Note About Programmable Fan:
The programmable fan feature will run the fan continuously during any time period when it is programmed to be on. This is the best way to keep the air circulated and to eliminate hot and cold spots in your building. If using IAQ mode, set fan to IAQ for any time period.

Temporary & Permanent Hold Feature

Temporary Hold:
The thermostat will display HOLD and RUN SCHED on the bottom of your screen when you press thekey. If you do nothing, the temperature will remain at this setpoint temporarily for a selected amount of time. After this, the program setpoint will then replace your temporary setpoint.

Permanent Hold:
With a temporary hold set, if you press the HOLD key at the bottom of your screen, you will see HOLD appear below the setpoint temperature in the display. The thermostat will now permanently stay at this setpoint and can be adjusted using the  keys.

To Return To Program:
Press the RUN SCHED key at the bottom of your screen to exit temporary and permanent holds.

Features

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/Next Step 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.

Energy-Efficient Globe Note: The energy-efficient globe indicates the occupant is making an energy-efficient choice in temperature control. This is not a tech setting but the energy-efficient globe will always appear on the thermostat screen when the setpoints are in a setback state. This feature will only work when programming is turned on.

Filter Change & Other Reminders

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. On 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.
