do not guarantee a 1-year life span.

Do not mount or place Remote Sensors in locations:
· Close to hot or cold air ducts · That are in direct sunlight · With an outside wall behind the thermostat · In areas that do not require conditioning · Where there are dead spots or drafts (in corners or behind doors) · Where appliances could radiate heat · Do not set it next to or on hot appliances · Do not put it in your pocket or hold in your hands for a long period of time. · Body heat will distort the temperature reading.

Insert 2 AA Alkaline batteries (included). High quality alkaline batteries are recommended.

Remote Sensing Communication
Connecting To The PROsync System
Establishing communication between a remote sensor and the equipment module
The main thermostat and equipment module in this package are linked at our factory. Upon power up, they will automatically begin to communicate. If you wish to add additional remote sensors, follow the instructions on this page.
How To Pair
1. Press the PAIR button on the equipment module. The equipment module will begin double blinking pink for 2 minutes while it listens for a new remote.
2. Press and hold the light button on the unpaired remote sensor to be added. The remote sensor will show “PAIRING” on the main screen.
3. When the remote sensor is successfully paired to the equipment module, the LCD will display “PAIRED” and the equipment module Pair button LED will blink green.
4. Repeat the process for additional remote sensors.
Network Troubleshooting
For any of the conditions listed below, please visit our website for troubleshooting instructions at www.pro1iaq.com/prosync
If your remote shows “NO COMM TO BASE” in the text field, this indicates the remote thermostat cannot communicate with the equipment module.

Remote Sensor Configuration

Locking Out System Control At The Remote

KEYPAD LOCKOUT The amount of control available at each remote can be limited using the Keypad Lockout feature. To use this feature, you must first navigate to the Keypad Lockout tech setting by holding the + and buttons together for 3 seconds and pressing the system button until you reach Keypad Lockout. You have three levels of limiting access to choose from. OFF Allows all functionality at the remote sensor based on the system application. PARTIAL Disables the fan and system button, only allowing the user to change the Set At temperature. FULL Disables all control at the remote sensor, only allowing the user to view the current operation. If this setting is set to Partial or Full, the lock icon will appear on the home screen.

Remote Sensor Configuration
Manually Overriding The System (Non-programmable)
If Keypad Lockout is set to OFF or PARTIAL, you have the ability to override the system from the remote sensor. If any button is pressed, the sensor will temporarily take control of the entire system for four hours. If at any point another button is pressed from that sensor, the four-hour time starts over. If you interact with any other remote sensor, it will start the timer over, and that sensor will take control of the system.

Remote Sensor Configuration
Manually Overriding The System (Programmable)
After the four-hour override has passed without any interaction on any of the remote sensors or thermostats in the home, the system willreturn to the previous or default control point. If the system has been running a program, it will return to the schedule based on the time of day.

Benefits To Using The PROsync Wireless System

When using remote sensing, this system can be configured four separate ways to maximize comfort for homeowner and cater to each of their unique lifestyles.

80
75
70

System Averaging
System Averaging will average all remotes together to provide a more accurate temperature of the entire home. Adjusting the temperature from any remote will temporarily put that room in control of the system. If the upstairs thermostat reads 80 while the basement reads 70 the system will condition the home to a 75 ambient.

Scheduling
With scheduling the system you can make different rooms in control for each part of the day. For homeowners with predictable schedules, this ensures each room will be the target temperature when scheduled to be used. Making the kitchen in control in the morning, your home office during the day, your living room in the evening, and your master bedroom at night is a great hands- free approach to maximize comfort. To turn Scheduling on or off, see the instructions for the “Program Mode” tech setting in the main thermostat manual on page 22.

Occupancy Sensing (Last Seen Mode)
This is the perfect solution for homes with a single occupant with less predictable schedules, using the built-in occupancy sensors moves the comfort around the home without the need for scheduling. As soon as someone enters a room, it takes control of the system. To turn Last Seen Occupancy Sensing on, see the instructions for “Occupancy Mode” tech setting in the main thermostat manual on page 31.

Occupancy Sensing (System Average Mode)
This is an excellent solution for a home with multiple occupants. Each time a remote senses occupancy, it starts an automatic, internal timer. The system is controlled using the average of the temperatures from only the remotes with active timers. When a remote’s timer expires, the system removes that remote from the average. To turn System Average Occupancy Sensing on, see the instructions for “Occupancy Mode” tech setting in the main thermostat manual on page 31.

Unlike other models, keypad lockout is always engaged if it is set to PARTIAL or FULL.

OF

KEY LOCKOUT

Use the + and – buttons to select OFF, PART, FULL OF – OFF= keypad lockout has been disabled. PA – PARTIAL= partial keypad lockout, which locks all the keys except the or setpoint keys. FU – FULL= full keypad lockout, which locks out all the keys.

Set the level of sensitivity of the occupancy sensor. Lowering the sensitivity will cause the sensor to respond only to larger movements.
Occupancy Sensitivity Setting
(Only displayed if Occupancy Control
is ON)

High Sensitivity(3): This is the most sensitive setting and will detect very slight motions. This is the recommended setting because it will work well for nearly all applications,and will detect any movement.

setting. This is less likely set

off by pets.

Low Sensitivity(1): This is the least sensitive setting and can be used in areas of heavy traffic. Pets, small children, or people more than 20′ from the sensor location are least likely to trigger the sensor .
