Honeywell vs LUX Thermostat Specs
Programmability
The LUX PSP511LC offers distinct scheduling flexibility with 5/2-day programming. You can set separate programs for weekdays and weekends, allowing for tailored comfort based on your routine. It supports up to four periods per day for both heating and cooling. The Honeywell TH1100DV1000 does not list programmable features in its specifications. It is designed as a simple heat-only unit without scheduling capabilities. If you need to automate temperature changes based on your daily schedule, the LUX model provides the necessary control. The Honeywell unit relies on manual adjustments.
Wiring Requirement
The Honeywell TH1100DV1000 requires a 2-wire setup, which simplifies installation for basic systems. This low wiring requirement makes it suitable for straightforward heat-only configurations. The LUX PSP511LC does not explicitly state its wire count in the provided data, though it supports single-stage heating and cooling. If you have a basic 2-wire system, the Honeywell unit is explicitly compatible. For more complex setups involving multiple stages or specific hydronic systems, the LUX model lists incompatibilities with multi-stage heat pumps and 3-wire hydronic systems. You must verify your existing wiring matches the Honeywell requirement for a direct fit.
Display Type
The Honeywell TH1100DV1000 features a backlit display, ensuring readability in low-light conditions. It continuously shows the ambient measured temperature, keeping you informed of the current room climate at all times. The LUX PSP511LC specifications do not mention a backlit screen or continuous ambient temperature display. While the LUX unit includes a speed dial for programming, the lack of a lit display may make reading the settings difficult in dark rooms. If visibility is a priority for you, the Honeywell model provides a clearer interface with its illuminated screen.
Temperature Control Range
Both thermostats offer a similar adjustable temperature scale for comfort management. The Honeywell TH1100DV1000 allows settings from 40 to 90 degrees Fahrenheit. The LUX PSP511LC provides a range from 45 to 90 degrees Fahrenheit. The Honeywell unit offers a slightly wider lower limit, allowing for cooler settings down to 40 degrees. The LUX model starts at 45 degrees. This difference is minor for most households, as both units cover the standard comfort range. You can set either device to maintain your preferred indoor climate without significant restrictions on the lower end.
Build and Size
The physical dimensions and weight of each unit differ slightly. The Honeywell TH1100DV1000 measures 2.88 inches in width, 4.69 inches in length, and 1.13 inches in height, weighing 7.3 ounces. The LUX PSP511LC is slightly larger, measuring 3.25 inches wide, 5 inches long, and 1.5 inches high, with a weight of 1 pound. The LUX unit is heavier and bulkier, which may affect mounting on certain wall plates. The Honeywell model is more compact and lighter. If space behind the wall is limited or you prefer a smaller footprint, the Honeywell unit is the more suitable choice.
Which Honeywell or LUX Thermostat Fits You
Renters needing simple heat-only control
The Honeywell TH1100DV1000 requires only two wires, making installation easy for basic heating systems. It runs on batteries, so you do not need to worry about hardwiring power sources. The backlit display ensures you can read the temperature clearly in low light. This model focuses solely on heating, which simplifies operation if you do not need cooling integration.
Users wanting weekday and weekend schedules
The LUX PSP511LC allows you to program five weekdays and two weekend days separately. You can set up to four different time periods each day for heating or cooling. This flexibility helps you adjust temperatures based on your specific daily routine. The speed dial feature makes entering these schedules quick and straightforward without complex menus.
People needing precise temperature management
The LUX model offers a temperature control range from 45 to 90 degrees Fahrenheit. It includes a keyboard lockout feature to prevent accidental changes. This precision allows for tighter comfort control compared to the Honeywell unit. The ability to manage both heating and cooling stages provides more comprehensive climate management for your home.
