This article details information available in provided documentation regarding Lennox thermostat models, installation, operation, and troubleshooting.
Model Overview
Several Lennox thermostat series are documented. The ComfortSense 5500 is a color touchscreen programmable thermostat, with documentation updated in 2015. The ComfortSense 7000 series, a touchscreen programmable thermostat, has documentation updated in 2009. The ComfortSense 7500 is a color touchscreen programmable thermostat, with installation manuals updated in 2017. The iComfort E30 is a smart thermostat with documentation updated in 2018. The Elo183B series also has available documentation, updated in 2015. Older models include the Elite series, with documentation from 2005, and the 51M37 Merit series. Identifying the correct model number is crucial, typically found on a label on the back of the device or within the menu on the LCD display.
Installation Procedures
Installation procedures differ based on the thermostat model. The iComfort M30 installation and setup manual is specifically referenced. The documentation details commissioning screens and settings that installers use to configure the system. These include setting the dealer ID number, dealer phone number, date, time, and temperature units (°F or °C). Terminal settings and system setup are also configurable during installation. Advanced settings allow for configuration of the number of stages for air conditioning and heat pump units. The iComfort M30 commissioning process begins after power is applied, displaying a Lennox splash screen before presenting the installer with setup screens.
Operating Instructions
Programming and scheduling functions vary between older and newer models. Older models typically use physical buttons labeled MENU, PROGRAM, or PROG to access scheduling options. Models with a SCHED button allow users to navigate through SCHED > EDIT to set schedules. Newer touchscreen models, such as the iComfort series, access programming through the Features screen, accessible via the right arrow from the Home screen, then selecting “edit programs.” The HELP function is available for simple instructions on these newer models.
Temperature hold functions also differ. Older models allow temporary overrides using the Up/Down buttons, with a HOLD button for permanent overrides. Models with HOLD TEMP offer options for permanent hold or vacation hold. Newer touchscreen models allow overrides by pressing a set temperature button (cool to or heat to).
Fan settings are adjusted by pressing the FAN button, which cycles through AUTO, ON, and CIRCULATE modes. For models with modes/schedules options, such as the iComfort E30, the fan icon is selected through the modes/schedules menu.
Resetting the Thermostat
Reset procedures vary by model. Some older models have a recessed, unlabeled reset button located behind the product or within the door. Pressing or long-pressing this button resets the thermostat to factory defaults. Newer models typically have a reset function within the settings menu accessible through the interface. Due to model-specific variations, it is recommended to consult the correct Lennox thermostat manual for the specific model.
Troubleshooting Common Issues
Several common issues are addressed in the documentation. A frequent problem is Wi-Fi connectivity. Troubleshooting steps include checking for changes to the network and attempting to reconnect the thermostat. Other potential issues and solutions are not detailed in the provided documentation.
Advanced Settings and Commissioning
The iComfort M30 offers advanced settings accessible through a dedicated menu. These settings allow for configuration of various system parameters, including the number of stages for air conditioning and heating units. Commissioning screens, accessed during initial setup, allow installers to enter dealer information, set the date and time, and configure terminal and system settings. The documentation provides tables outlining the available menu settings and parameters for both commissioning and advanced settings.
