Setting the Temperature on Your Lennox L3532H

This is the most basic function. Simply use the up and down arrows to increase or decrease the desired temperature. The display will immediately reflect your changes. The thermostat will automatically adjust your HVAC system to reach the target temperature.

Selecting System Mode (Heating, Cooling, Auto)

The System Switch allows you to choose the operating mode of your HVAC system:

Heat: Activates the heating system.
Cool: Activates the cooling system.
Auto: Automatically switches between heating and cooling based on the programmed schedule and the current temperature. This is the most energy-efficient setting for most users.

Controlling the Fan

The Fan Switch provides two options:

Auto: The fan runs only when the heating or cooling system is operating. This is generally the most energy-efficient setting.
On: The fan runs continuously, circulating air even when the heating or cooling system is off. This can improve air quality but consumes more energy.

Using the "Hold" Function

The "Hold" button temporarily overrides your programmed schedule. This is useful for making short-term adjustments, such as setting a warmer temperature for a few hours. Remember to cancel the "Hold" function when you want the thermostat to resume its normal schedule. The thermostat will typically revert to the programmed schedule after a set time, or you can manually cancel the "Hold" to return to the schedule.

Accessing the Programming Menu

The "Menu" button opens a menu of advanced settings, including:

Programming Schedules: Customize your thermostat's temperature settings for different times of the day and days of the week. (More detail on this below)
System Preferences: Adjust settings like fan speed and temperature display units.
Filter Change Reminders: Set reminders to replace your HVAC system's air filter.

Programming Your Lennox L3532H Thermostat

Weekday mornings: A comfortable temperature for waking up.
Weekday afternoons: A slightly cooler temperature while you're away.
