BEFORE YOU START
MAKE THE MOST OF YOUR MAESTRO
The MAESTRO controller• thermostat can function on its own, but it offers more options when used with MAESTRO thermos-
tats and the MAESTRO app. By using the complete MAESTRO system, you’ll benet from maximum comfort, exibility and
energy savings.

WHERE TO INSTALL YOUR MAESTRO CONTROLLER•THERMOSTAT?
A bit of planning will optimize Maestro’s mesh network and ensure that devices communicate well. The controller• thermostat
allows you to control the other MAESTRO thermostats in your home. Plan to install the controller in a central location. Doing
so will facilitate communication with the various rooms.
In this example, the controller could be positioned at the entrance to the living room (1) or dining room (2). The signal may
have a hard time getting to the master bathroom as the washer/dryer (3) and shower (4) could be barriers. If a MAESTRO
thermostat is placed in the master bedroom (5), it will help relay the signals between the controller and the master bathroom
thermostat. Since the controller• thermostat also serves as a thermostat, it will control the temperature of this room.

You must install the controller•thermostat at approximately 1.5 m (5 ft.) from the oor, on an indoor wall that faces the heating
system. The controller• thermostat must be mounted on an electrical box.
ATTENTION : To avoid any risk of overheating, leave a clearance of at least 30 cm (12 in.) around the controller• thermostat to
ensure proper ventilation. Also, the front of the unit should be completely clear of any obstruction to ensure optimal functio-
nality. For example, do not install the controller•thermostat behind curtains or furniture.
To avoid getting false temperature measurements, do not install the controller•thermostat in any of the following locations:
• Near a window or close to a door leading outside
• In an area exposed directly to the light or heat of the sun, a lamp, a replace or any other heat source
• Near an air outlet
• Near concealed ducts or a chimney
• Where there is poor air ow (e.g. behind a door)
• Where there is a high concentration of dust
• Where there are frequent air drafts (e.g. top of stairs)

Take full advantage of your MAESTRO controller• thermostat by also using the MAESTRO thermostats and the MAESTRO
mobile app. Using the complete MAESTRO system enables you to create your own ecosystem in your home and control it at
any time, from anywhere.
FOUR STEPS TO MANAGING THE COMFORT OF YOUR HOME
1INSTALL YOUR MAESTRO CONTROLLER
•THERMOSTAT
Follow the instructions in this guide to install your MAESTRO controller• thermostat. Don’t forget that your
controller• thermostat also serves as a thermostat for the room in which it is installed.
2INSTALL YOUR MAESTRO THERMOSTATS
Now install your MAESTRO thermostats. For instructions on how to do this, read the thermostat’s installation and
user guide. To maintain full control over the temperature of your home, you must have a thermostat in each room.
NOTE: A MAESTRO thermostat can control up to 4,000 watts.
READ THIS GUIDE AND WATCH THE INSTALLATION VIDEO
Before you start, take a few minutes to carefully read this guide and watch the step-by-step video on installing the MAESTRO
controller• thermostat. It will ensure safe and easy installation.
The installation video is at the bottom of this page: www.stelpro.com/en-CA/maestro

- 10 -- 10 -
3INSTALL THE MAESTRO APP AND CREATE YOUR MAESTRO ACCOUNT
Download and install the MAESTRO app available for free in the App StoreTM or on Google PlayTM.
After installing the app, create your user account. Once your MAESTRO network is set up, you will be able to control
your MAESTRO system with any mobile device that is connected to this account.
NOTE: Since only one account can control your MAESTRO system, use an email address and password
that you can share with those who will need to manage your MAESTRO system.
4BUILD YOUR MAESTRO NETWORK
Follow these steps to build your MAESTRO network:
1- Connect the controller•thermostat to your Wi-Fi network (see page 19).
2- In the MAESTRO app, enter the registration code displayed on the controller•thermostat screen to create a home.
3- In the MAESTRO app, the “Connect a thermostat to my MAESTRO system” feature will activate and set the
controller• thermostat in thermostat pairing mode (see www.stelpro.com/en-CA/support-maestro for more details
on how to use the MAESTRO app).
4- Connect the thermostats to the controller• thermostat, one at a time (see the “Connecting a thermostat to the
controller• thermostat” section on page 21).
5- Once the connection is complete, the thermostat will appear in the MAESTRO app. Take this opportunity to give it
a name that will be easily recognizable.
NOTE: In your network, each thermostat is connected to the controller • thermostat via a thermostat that
is located nearby. You therefore need to connect your thermostats starting with the one closest to the
controller • thermostat and gradually working outwards. You may need a Zigbee repeater to get around
obstacles or to strengthen the Zigbee signal.

- 11 -- 11 -
1CUT OFF POWER SUPPLY
To avoid any risk of electric shock, cut off the power supply on the lead wires from the electrical panel. Make sure the
power is off by checking, for example, that the heating system remains off even if the setpoint temperature is higher
than the ambient temperature (mechanical thermostat).
INSTALLING THE MAESTRO
CONTROLLER•THERMOSTAT
INSTALLATION OF THE CONTROLLER • THERMOSTAT MUST BE DONE BY A QUALIFIED ELECTRICIAN.
IMPORTANT

- 12 -- 12 -
2REMOVE EXISTING THERMOSTAT
If an existing thermostat is being replaced, please follow these steps:
NOTE: These instructions apply to a thermostat with a °STELPRO mounting plate.
1- Loosen the screw at the base of the thermostat, without completely removing it, to separate the thermostat from
the mounting plate.
2- Gently pull the thermostat to gain access to the wires.
3- Disconnect the thermostat wires from those of the heating system and power supply.
4- Remove the mounting plate.

- 13 -- 13 -
3SECURE THE MAESTRO CONTROLLER• THERMOSTAT MOUNTING PLATE
Secure the MAESTRO controller• thermostat mounting plate to the electrical box using the screws supplied.
1- Loosen the screw at the base of the MAESTRO controller• thermostat, without completely removing it, until the
controller• thermostat and the mounting plate are no longer holding together.
2- Slide the mounting plate downward and then pull on it to separate it from the controller• thermostat.
3- Using the mounting screws supplied (2), secure the MAESTRO controller• thermostat mounting plate to the electrical
box. Ensure the plate is perfectly straight so that the controller• thermostat is also straight.
4- Pass the power supply wires through the large opening at the centre of the mounting plate.
NOTE: You can position the mounting plate either to the left, in the centre or to the right of the electrical box,
according to your needs. (See image below).

- 14 -- 14 -
4CONNECT THE WIRES
Using the caps supplied (3), connect the wires of the MAESTRO controller• thermostat to those of the heating system
and power supply according to the corresponding connection diagram. Tighten the caps onto the wires to ensure
the connection is secure. Then place all the wires inside the electrical box.
NOTE: If the electrical wires are aluminum, use
CO/ALR connectors instead (not supplied).
NOTE: Since controller
•
thermostat wires have a
polarity, the way they are connected is important.
IMPROPER WIRING
IS A FIRE HAZARD.

5SECURE THE CONTROLLER • THERMOSTAT ON THE MOUNTING PLATE
Align and secure the controller• thermostat on the mounting plate.
1- Ensure the air vents in the controller•thermostat are clean and clear of any obstruction.
2- Align the slot on the top of the controller• thermostat with the slot on the mounting plate.
3- Then secure the controller•thermostat to the mounting plate making sure that the wires do not get pinched
between the unit and the mounting plate.
4- Tighten the screw at the base of the controller• thermostat to secure it in place.

- 16 -- 16 -
6TURN POWER BACK ON
Restore power to the heating system and controller• thermostat. Then ensure the controller• thermostat turns on.
If the controller• thermostat does not turn on, touch the screen. The controller• thermostat should turn on. If it
doesn’t, read the “Controller• thermostat troubleshooting” section on page 40.
Once installed, the controller• thermostat will prompt you to choose a language, temperature format, time format,
heat mode and Lobby mode if the heating mode is Fan Forced heater. If the temperature is below 0 °C (32 °F), the
home screen will display Cold. If the temperature exceeds 50 °C (122 °F), the screen will display Hot.
