USING THIS MANUAL
For the latest Instructions go to: WWW.MRPEXSYSTEMS.COM
To cover all MrPEX®Wireless Products without requiring customers to download unnecessary
documentation, the Wireless System Guide has been divided into 5 volumes. Volume 1 is required for all
wireless systems since it covers installation of the Gateway and the MrPEX®Smart Home application.
The remaining volumes are specific to a particular group of controls.
Below is a description of several icons used to direct the reader’s attention.
Special Attention Boxes
This manual uses special attention icons to alert the reader of important safety concerns, information
important to reliable operation of the controls or helpful installation/setup information.
Safety:
Indicates a condition which may cause severe
personal injury, death or major property damage
Important Information:
Indicates information which requires special
attention for correct operation of the control
Your Benefit:
Indicates helpful installation or setup information

SYSTEM OVERVIEW
MrPEX®connected HVAC control systems use Zigbee-based communications protocol to provide a
universal language for smart components to work together seamlessly and securely with an internet
connection. If the internet connection is interrupted or dis connected, the HVAC component will continue
to operate together.
MODULE 3 – WIRELESS HVAC THERMOSTATS
INTRODUCTION
SECTION 1
By connecting the Gateway to your home network, the system is connected to the worldwide web.
Monitor or adjust your HVAC system from anywhere via the MrPEX®Smart Home application. If the
connection to the internet is lost, the system continues to function with the settings selected.

Step 2. If replacing an existing thermostat, review and record the existing wiring configuration:
• Remove thermostat from the wall to expose the wiring terminals
• Take a photograph or note the wire colors and designations (see wiring reference above)
• Attach wire labels provided to each of the existing thermostat wires
Step 3. Remove existing thermostat.
BEFORE BEGINNING the installation procedure, turn o power to the
heating system.
Label wires to correspond to
thermostat terminals.
Wrap wires around a pencil or similar
object to prevent them from falling into
the wall void.
