About this product
Product Description
The RESIDEO HWTH1110U4000-U is a low-voltage, non-programmable digital thermostat designed for single-stage heating and cooling applications in residential and light commercial settings. Operating on 24V AC, it supports conventional heat-cool systems as well as single-stage heat pumps without auxiliary heat and steam or radiant hot water systems. The large digital display shows temperature in Fahrenheit or Celsius, and the push-button interface provides straightforward control. A temperature sensitivity of plus or minus 1 degree F and a control range of 50 to 99 degrees F for cooling and 32 to 90 degrees F for heating make it a reliable replacement for standard low-voltage thermostats. A licensed HVAC technician handles installation.
This thermostat is suited for residential and light commercial HVAC applications where a simple, non-programmable control is preferred over a programmable or smart device. Compatible system types include 24V AC conventional single-stage heat and cool systems, single-stage heat pumps without auxiliary heat, and steam or radiant hot water systems. System settings cover Heat-Off-Cool-Auto modes. Fan is set to Auto. The unit ships with a decorative cover plate with J-Box adaptor, mounting hardware, and a UWP mounting plate, making it a direct swap in most standard thermostat locations.
