The LuxPro PSD111+ is a high-precision digital non-programmable thermostat designed for residential and light commercial HVAC systems that require straightforward temperature control. This thermostat is ideal for users who prefer manual temperature adjustments without the complexity of scheduled programming.
It features a large, easy-to-read backlit display, making it convenient for day or night viewing. The PSD111+ operates on either 24V system power or two AA alkaline batteries, offering flexibility in installation and power backup.
It is compatible with a wide range of systems including single-stage heating and cooling systems, heat-only systems, cool-only systems, gas/electric furnaces, and millivolt systems like wall or floor heaters. However, it is not compatible with multi-stage systems or 120/240V systems without a transformer.
The thermostat offers adjustable temperature swing settings, compressor short cycle protection, and keypad lockout to prevent unauthorized adjustments. With temperature limit settings, you can restrict the maximum and minimum temperature settings—ideal for rental properties or public settings.
This thermostat is built for reliable, energy-efficient temperature control, and includes features such as Fahrenheit/Celsius display options, low battery warning, and temperature calibration.
