Resideo Llc RTH11B/N Non-programmable Thermostat

Product Description

The RESIDEO LLC RTH11B/N is a non-programmable thermostat designed for straightforward temperature control in residential heating and cooling applications. It supports 1 heat and 1 cool configurations and operates on 750 mV systems, making it compatible with hot water heat and forced air systems using gas, oil, or electric heat sources. The unit is powered by 2 AA batteries, which are not included. A large display with clear font aids daily readability and makes adjustments quick. Licensed HVAC technicians and experienced DIYers install this unit in place of existing low-voltage thermostats where a simple, reliable control is preferred over programmable or smart alternatives.

This thermostat is suited for residential forced air systems running gas, oil, or electric heat, as well as hot water heating systems. It is not compatible with electric baseboard heat operating at 120 to 240 volts. The unit supports customizable air filter change reminders and adjustable display settings. It is sold in packages of 4 units per carton, making it practical for multi-unit residential jobs or property maintenance accounts where standardized, no-frills controls are the preferred solution.
