Battery Door Information

Caution: When the battery icon 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 indicator is displayed when the AA battery power is low. If the user fails to replace the battery within 21 days, the screen will only show the low battery indicator but maintain all functionality. If the user fails to replace the batteries after an additional 21 days (days 22-42 since the first “low battery” display) the setpoints will change to 55˚F (Heating) and 85˚F (Cooling). If the user adjusts the setpoint away from either of these, it will hold for 4 hours and then return to either 55˚F or 85˚F. After day 63 the batteries must be replaced immediately to avoid freezing or overheating because the thermostat will shut the unit off until the batteries are changed.

Setting The Humidity

Follow the steps below to change your target humidity setpoint. Press the humidity button. Use the or button to select the target humidity setpoint. Press DONE when completed.

Note:
The target humidity setpoint is not programmable. Unlike temperature, humidity does not change quickly and should not be programmed.

Note:
Humidity is only energized during the heat. Dehumidity is only energized during cool. Heat and cool each have their own target setpoints.

Increasing Humidity
The table on the right shows recommended indoor humidity levels in relation to outdoor temperatures during heating (adding humidity). Consult your professional HVAC technician for recommended settings for your climate.

Outside  Recommended Temperature (0°)  Relative Humidity

• +20° and above     35% to 40%
• +10°                         30%
• 0°                            25%
• -10°                         20%
• -20°                         15%

Set Time

   Saturday:
   Repeat steps 4 through 6 for Sunday time periods.

Additional step if indoor remote sensor is connected.
The master thermostat will either average all sensors (system average) or only use one sensor for the system ambient temperature (priority). The default setting is SYSTEM AVERAGE, which means all sensors are averaged to create the system average ambient temperature reading. The NEXT ZONE key can be pressed to change the priority. The system information area of the display shows the priority. For Example, There is a remotely connected and it is named REMOTE 1. If the NEXT ZONE key is pressed until REMOTE 1 is shown, then the REMOTE 1 ambient temperature reading will be used exclusively for that time period. All other sensors will be ignored.

A Note About Auto Changeover:
When in Auto you have the ability to switch between auto heat or auto cool by pressing the system key. This can be done once the current mode has reached its set point. For example: if in auto heat, the heat
setpoint must be satisfied before the thermostat will allow you to switch to auto cool. You can switch out of the auto by holding down the system key. To get back into auto, you must toggle the system key to auto.

Set 7-Day Program Schedule
Monday

1. Select HEAT or COOL with the SYSTEM key.
   Note: You have to program heat and cool each separately.
2. Press the MENU key.
3. Press SET SCHED. Note: Monday is displayed and the WAKE or OCCUPIED icon is shown. You are now programming `the WAKE or OCCUPIED time period for that day.

An additional step is if the indoor remote sensor is connected
The master thermostat will either average all sensors (system average) or only use one sensor for the system ambient temperature (priority). The default setting is SYSTEM AVERAGE, which means all sensors are averaged to create the system average ambient temperature reading. The NEXT ZONE key can be pressed to change the priority. The system information area of the display shows the priority. For Example, There is a remotely connected and it is named REMOTE 1. If the NEXT ZONE key is pressed until REMOTE 1 is shown, then the REMOTE 1 ambient temperature reading will be used exclusively for that time period. All other sensors will be ignored

A Note About Programmable Fan
The programmable fan feature will run the fan continuously during any time period it is programmed to be on. This is the best way to keep the air circulated and to eliminate hot & cold spots in your building.

Next Zone (Only if the indoor remote is connected)
The NEXT ZONE key cycles through all sensors connected to your wireless system. SYSTEM AVERAGE shows the average ambient temperature of all connected sensors. LOCAL shows the ambient temperature of the thermostat only. The name of the remote sensor will show and the ambient temperature for that sensor will be displayed. For more information please refer to the Indoor Remote Sensor User Guide.

Keypad Lockout Note
If appears in the display, then the keypad is locked. All or some of the keys will not work. Hold the keys for 3 seconds to remove the lock. Use the same procedure to lock the display
