FAQ Maestro

All the steps to configure your Maestro network are included in the user guide. You’ll also find additional information and answers to frequently asked questions below.

Installation and start-up

Where should I install the controller • thermostat or thermostat in the house?

It must be installed in a central room where it will be easily accessible, about 5 ft. (1.5 m) from the floor, on an interior wall that faces the heating system. The controller • thermostat must be installed in a central location in the house (according to the number of levels and surface area) to make network connections easier.

What is the maximum recommended distance between the controller • thermostat and the thermostat?

When no barrier is present, the maximum distance between the two devices should not exceed 33 feet. In the presence of signal barriers such as a wall, a door or furniture, the distance should be slightly less than 33 feet.

What should I do if the controller • thermostat or thermostat doesn’t light up after it is installed?

Make sure the heating system’s circuit breaker in the electrical panel is OFF.

Make sure the leads (of the controller • thermostat or thermostat) are properly connected and the caps are firmly tightened (see the Installation section of your product’s user guide).

If the heating system has a switch, make sure it is ON.

Why aren’t the buttons responding, except for advanced menu access?

The thermostat is locked. Deactivate lock mode.

Maestro network/Zigbee connectivity

How can I add a thermostat to my Maestro ecosystem?

The controller • thermostat must be in connection mode. To do so, go to Settings → Zigbee Connection → Add a new thermostat.

What should I do if I cannot connect my Maestro thermostats to the controller • thermostat?

Refer to the Connectivity issues page for the full connection issue procedure.

Can my house’s construction interfere with wireless data transmission?

Yes. As a result, you may need to reposition your thermostat or install Zigbee repeaters.

Can appliances interfere with wireless data transmission?

Yes, if they are located in a straight line between two devices. You may need to reposition your thermostat or install Zigbee repeaters.

Wi-Fi connectivity

What should I do if the controller • thermostat does not display my home’s Wi-Fi network?

Make sure the controller • thermostat is installed in a location where your router’s Wi-Fi signal is strong.

Make sure your network isn’t configured to hide its name and isn’t a corporate network

What should I do if the Wi-Fi connection failed?

Make sure you entered the correct password.

The connection may also have failed due to an intermittent problem with the Wi-Fi network. Try to reconnect later.

Cloud services may have crashed. As a result, the controller • thermostat is unable to connect to the Stelpro Cloud. In this case, a message will appear at the top of the www.stelpro.com website’s home page.

Heating

What should I do if the controller • thermostat or thermostat doesn’t display the correct ambient temperature?

Make sure there are no drafts or heat sources near the controller • thermostat or thermostat.

Moreover, although the temperature reading sensors are located in the thermostat, the ambient temperature displayed is the one estimated for the centre of the room. This sensing mode is dictated by the standards governing thermostats. It aims to maximize people's comfort in the space they inhabit. For this reason, it’s normal for a thermometer placed just next to a thermostat not to read the same ambient temperature.

The heating system is running continuously, even when the temperature setpoint has been reached?

Make sure the thermostat’s or controller • thermostat’s leads are properly connected (see the Installation section of your product’s user guide).

NOTE: The controller • thermostat and thermostat can also command residual heat to maintain the temperature setpoint once it is reached.

What should I do if the heating system isn’t operational even though the controller • thermostat or thermostat indicates that it is?

Make sure the controller • thermostat leads are properly connected (see the Installation section of your product’s user guide).

What should I do if the fan heater turns on and off frequently?

Go to the heating mode selection menu of the controller • thermostat and select “Fan-Forced Heater”.

On the thermostat go to the heating mode selection menu (menu 3) and select ON.

What should I do if the thermostat is hot to the touch?

Even when it’s operating normally, the thermostat’s housing may become hot to the touch. This does not affect the efficiency or operation of the thermostat and poses no risk.

IFTTT

What does IFTTT mean?

IFTTT means “If This, Then That” (i.e. if A happens, do B). It’s a platform that allows one occurrence to trigger another and lets you program actions between your smart objects. Indeed, one of your devices or another service available on IFTTT can be configured to trigger these actions. Your Maestro smart controller • thermostat can act as a trigger for an action as well as a reaction to it.

For example, if your Philips Hub lights turn on, then the status of your Maestro controller changes to “I'm home.”

Available on iOS, Android, PC and voice assistants (Amazon Alexa and Google Home), Stelpro's IFTTT applets let you create your own automated actions for the Internet of Things.

How do I create personalized IFTTT actions?

You can create a host of IFTTT actions to link your systems.

  • Create an IFTTT account.
  • Log in to your IFTTT account.
  • Click "New Applet."
  • Click "+ this."
  • Choose the Stelpro (or other) service you want to use as a trigger.
  • Configure the trigger for the chosen service and click "Create trigger."
  • Click "+ that."
  • Choose the Stelpro (or other) service you want to use as an "action."
  • Configure the action for the chosen service and click "Create action."
  • Click "Finish."

Does the Maestro controller • thermostat act as a trigger or an action (reaction)?

The Maestro controller • thermostat can act either as a trigger or an action.

Which applets does the Maestro controller • thermostat offer?

The 10 default applets available are as follows:

                               

However, you can create other personalized actions which your Maestro controller • thermostat can use.

With which voice assistants are Maestro’s IFTTT applets compatible?

Maestro’s default applets are compatible with Google Home. You can also create your own applet with Amazon Alexa.

How do I activate/deactivate an IFTTT applet?

To activate or deactivate an applet:

  • Go to the “My applets” section.
  • Click on or tap the applet you want to activate/deactivate (toggle it from ON to OFF or vice versa).

Which IoT devices can I use with my IFTTT applets?

All IFTTT-compatible devices can be configured with your Stelpro products and applets.

With which social media platform and messaging services can I use IFTTT for Maestro?

All the main social media platforms (Facebook, Twitter, etc.) are compatible with IFTTT for Maestro.
