Get More From Your Lennox S40

Your Lennox S40 Smart Thermostat does much more than control the temperature in your home. It can help manage your comfort, schedules and humidity, provide remote access from your phone, and even help Alpine Refrigeration identify potential problems with your heating and cooling system.

Connect Your S40 to Alpine Refrigeration

Give Alpine the Ability to Help — Even Before We Arrive

Your Lennox S40 can notify Alpine Refrigeration when your heating or cooling system detects certain problems and allow us to access important diagnostic information remotely.

By enabling Dealer Support Access, Alpine may be able to identify a problem sooner, remotely troubleshoot certain issues and, when a service visit is necessary, have valuable information about your system before our technician arrives.

There is no charge to enable Dealer Support Access.

How to Enable Alpine Dealer Support

Step 1 — Open the Menu

From the home screen of your Lennox S40:

  1. Tap the Menu ☰ button in the upper-left corner.
  2. Select Lennox Dealer Support Access.
  3. Select Dealer Support from the menu on the left.

Step 2 — Enable All Three Features

Turn the slide button ON for each of the following:

Remote Sharing
Allows Alpine to view historical system and status data and fix most issues remotely with no service call.

Alerts & Notifications
Allows Alpine to receive system maintenance notifications and critical error alerts so we can contact you to help fix or send a tech.

Advanced Diagnostics
Gives Alpine the ability to access diagnostic information to help troubleshoot system issues and make adjustments.

We recommend enabling all three features to receive the greatest benefit from Alpine’s remote support capabilities.

🌡️ Temperature & Everyday Comfort Settings

The S40 gives you control over heating, cooling, fan operation and other everyday comfort settings.

You can manually adjust your heating or cooling temperature directly from the thermostat’s home screen.

If you’re using a programmed schedule, a manual temperature change may temporarily override your scheduled setting.

🏠 Use Away Mode

Leaving home for the day or heading away on vacation?

From the S40 home screen, simply tap Away in the lower-left corner.

The thermostat will use your preset Away heating and cooling temperatures until you return.

To change your Away temperature settings:

Menu → Settings → Away

When you return home, select Cancel to resume normal operation.

Your S40 also offers Smart Away, which can use your smartphone’s location to automatically adjust your home’s comfort settings when you leave and return.

💧 Adjust Humidity Settings

Your S40 can help manage your home’s humidity when compatible whole-home humidity-control equipment is connected to your HVAC system.

Humidity settings can help improve comfort during both heating and cooling seasons.
