1. Locate the TIMER ON Button

The first step in setting the timer on your Lennox AC remote is to identify the “TIMER ON” button. This button is typically labeled as “Timer On” or “Auto-On” and is usually located on the remote control itself.

2. Set the Timer

After pressing the TIMER ON button, the remote controller will display the current time and the last Auto-on setting time. Use the arrow buttons on the remote to adjust the time to your desired setting. The timer can be set in increments of one minute, and holding down the arrow buttons will increase or decrease the time in 10-minute intervals.

3. Confirm the Setting

Once you have set the timer to your preferred time, press the TIMER ON button again to confirm the setting. The remote controller will then display “TIMER ON” to indicate that the timer has been successfully set.

Advanced Timer Functions

TIMER OFF Function

In addition to the TIMER ON function, some Lennox AC remotes also feature a TIMER OFF function. This allows you to set the air conditioner to turn off at a specific time. The steps to set the TIMER OFF function are similar to the TIMER ON process, and you can use the arrow buttons to adjust the time accordingly.

Canceling the Timer

If you need to cancel the timer, simply press the TIMER ON or TIMER OFF button again. This will deactivate the timer, and the remote controller will no longer display the “TIMER ON” or “TIMER OFF” indicator.

Energy-Saving Mode

Some Lennox AC remotes also include an energy-saving function, which can help you save even more energy by automatically reducing the set temperature in cooling mode. This feature can be particularly useful when combined with the timer function, as it allows you to maintain a comfortable temperature while minimizing energy consumption.
