IMPORTANT: This thermostat is not compatible with:

• Systems with inductive loads

• Central heating systems

• Systems with resistive loads that are:

o inferior to 150 W at 120 VAC / 260 W at 208 VAC / 300 W at 240 VAC

o superior to 2000 W at 120 VAC / 3400 W at 208 VAC / 4000 W at 240 VAC

See page 25 for detailed technical specications of the MAESTRO thermostat.

To install your thermostat, you will need:

• No. 2 Phillips screwdriver

The two required screws are supplied.

- 4-- 4-

Before installing and operating this thermostat, the owner and/or installer must read, understand and follow these instructions

and keep them handy for future reference. If these instructions are not followed, the warranty will be considered null and void

and the manufacturer deems no further responsibility for this product. Moreover, the following instructions must be adhered

to in order to avoid personal injuries or property damages, serious injuries and potentially fatal electric shocks. All electric

connections must be made by a qualied electrician, according to the electric and building codes effective in your region.

• Do NOT connect this product to a supply source other than 120 VAC or 240 VAC, and do not exceed the load limits

specied.

• Protect the heating system with the appropriate circuit breaker or fuse. You must regularly clean dirt accumulations on the

thermostat.

• Do NOT use uid to clean thermostat air vents.

• Do NOT install thermostat in a wet place or on an external wall. However, installing it in isolated walls is allowed. To avoid

any risk of overheating, leave a clearance of at least 30 cm (12 in.) around the thermostat to ensure proper ventilation.

• Also, make sure that the air vents at the bottom and top of the thermostat housing are clear of any obstruction: blocked

air vents can lead to the unit overheating and affect its operation.

NOTE: °STELPRO reserves the right to modify its product without notice to improve operability. Therefore, the instructions in

this user guide many not entirely match all the functions of your thermostat. To obtain the most recent documentation, visit

the °STELPRO website.

IMPORTANT: HIGH VOLTAGE! CUT OFF POWER BEFORE INSTALLING UNIT OR DOING ANY MAINTENANCE.

WARNING

- 5-- 5-

WHERE TO INSTALL YOUR MAESTRO CONTROLLER•THERMOSTAT

Install a MAESTRO thermostat in each room where you want to control the temperature.

You must install the thermostat at approximately 5 ft. from the oor, on an indoor

wall that faces the heating system. The thermostat must be mounted on an electri-

cal box.

ATTENTION : To avoid any risk of overheating, leave a clearance of at least 12 in.

around the thermostat to ensure proper ventilation. Also, the front of the unit

should be completely clear of any obstruction to ensure optimal functionality. For

example, do not install the thermostat behind curtains or furniture.

To avoid getting false temperature measurements, do not install the 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)

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

thermostat. It will ensure safe and easy installation.

The installation video is at the bottom of this page: www.stelpro.com/en-US/maestro

- 6-- 6-

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 THERMOSTAT

INSTALLATION OF THE THERMOSTAT MUST BE DONE BY A QUALIFIED ELECTRICIAN.

IMPORTANT

- 7-- 7-

2REMOVE EXISTING THERMOSTAT

If an existing thermostat is being replaced, remove it and disconnect its wires from the heating system and power

supply.

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 sys-

tem and power supply.

4 - Remove the mounting plate.

- 8-- 8-

3SECURE THE MAESTRO THERMOSTAT MOUNTING PLATE

Secure the MAESTRO thermostat mounting plate to the electrical box using the screws supplied.

1 - Loosen the screw at the base of the MAESTRO thermostat, without completely removing it, until the 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 thermostat.

3 - Using the mounting screws supplied (2), secure the MAESTRO thermostat mounting plate to the electrical box. Ensure

the plate is perfectly straight so that the 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).

- 9-- 9-

4CONNECT THE WIRES

Using the caps supplied (2), connect the wires of the MAESTRO thermostat to those of the heating system and

power supply according to the corresponding connection diagram (2 or 4 wires). 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 thermostat wires do not have polarity,

the way they are connected is not important.

IMPROPER WIRING IS

A FIRE HAZARD.

IMPORTANT

- 10 -- 10 -

5SECURE THE THERMOSTAT ON THE MOUNTING PLATE

Align and secure the thermostat on the mounting plate.

1 - Ensure the air vents in the thermostat are clean and clear of any obstruction.

2 - Align the slot on the top of the thermostat with the slot on the mounting plate.

3 - Then secure the 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 thermostat to secure it in place.
