About RESIDEO

Resideo is a manufacturer of residential and light commercial HVAC controls, water system components, and related accessories. The company was formed in 2018 following a spin-off from Honeywell, and it continues to produce many product lines that originated under the Honeywell brand. Resideo's portfolio includes thermostats, air eliminators, ignition controls, water detectors, and other components used in heating, cooling, and plumbing systems. 3G Electric supplies Resideo products globally to plant engineers, maintenance managers, and procurement specialists who require reliable, specification-grade components for building automation and mechanical systems.

The Resideo product range covers several key categories. Thermostats include low-voltage non-programmable digital models, programmable units with soft-key or touch-screen interfaces, and analog heat-only devices. These thermostats support various system configurations, such as conventional and heat pump setups, with stages ranging from 1 heat/1 cool to 3 heat/2 cool. Many models offer features like automatic and manual changeover, 7-day or 5-1-1 programming, and fan settings of auto, on, or circulate. Communication options include Z-Wave Plus and Wi-Fi, enabling integration with building management systems and smart home platforms. Air eliminators, such as the PV150/U, are bronze-bodied inline separators designed to remove trapped air from water systems, reducing noise, corrosion, and flow restrictions. They are rated for up to 125 psi and 239°F, with connection types including female NPT and sweat. Ignition controls and water detectors round out the offering, providing safety and monitoring functions for gas-fired equipment and leak detection.

Technical buyers will find that Resideo products are built to standard industry specifications. Thermostats operate at 24V AC or line voltage, depending on the model, and include mounting hardware and adaptor plates for retrofit installations. Air eliminators feature durable bronze construction and are suitable for vertical mounting in hydronic systems. The product families are designed for ease of installation, with features like universal mounting plates and decorative cover plates. 3G Electric supports the Resideo line by maintaining inventory of these components and providing specification details, such as terminal designations, pressure ratings, and temperature ranges, to assist with selection. The company serves a global customer base, shipping to industrial, commercial, and institutional facilities. For procurement specialists, 3G Electric offers a streamlined path to obtain Resideo parts, with access to technical documentation and competitive quotes. Whether the application involves a simple heat-only thermostat replacement or a complex building automation upgrade, the Resideo catalog provides options that meet common HVAC and water system requirements.

Frequently asked questions

Common questions about RESIDEO from 3G Electric.

What types of Resideo thermostats are available for heat pump systems?

Resideo offers several thermostats compatible with heat pump systems. For example, the TH1320U4002/U supports up to 3 heat/2 cool heat pump configurations, while the TH2210U4005 handles standard heat and cool applications with automatic and manual changeover. These models are low-voltage and include features like soft-key controls or push-button interfaces. When selecting a thermostat for a heat pump, verify the required stages and terminal designations, such as O/B for reversing valve control. Resideo thermostats typically operate on 24V AC and may include mounting hardware and adaptor plates for various installation scenarios.

What are the pressure and temperature ratings for Resideo air eliminators?

Resideo air eliminators, such as the PV150/U, are rated for a maximum pressure of 125 psi and a maximum temperature of 239°F. These bronze-bodied inline separators are designed for water systems and feature connection options including 1/2 in female NPT or sweat. They are intended for vertical mounting and help remove trapped air to reduce noise, corrosion, and flow restrictions in hydronic heating or cooling loops. Always confirm the connection type and size match your piping before installation.

Can Resideo thermostats be integrated with smart home or building automation systems?

Yes, certain Resideo thermostats support integration with smart home and building automation platforms. The TH6320ZW2007 model features Z-Wave Plus technology, allowing it to communicate with compatible hubs and controllers. The THX321WFS3001W offers Wi-Fi connectivity and geofencing capabilities for automated temperature adjustments. These thermostats provide fan settings of auto, on, or circulate, and support heat and cool applications. Integration enables remote monitoring and control, which can be useful for light commercial buildings or residential settings where centralized management is desired.

What is the difference between Resideo's programmable and non-programmable thermostats?

Resideo's programmable thermostats, such as the TH2210U4005, allow users to set schedules for different times of day, often with 1-week or 5-1-1 programming options. Non-programmable models, like the TH1320U4002/U, provide simple manual temperature adjustment without scheduling. Programmable units can reduce energy consumption by automatically adjusting temperatures when spaces are unoccupied, while non-programmable units are typically used where a constant temperature is required or where simplicity is preferred. Both types are available for conventional and heat pump systems, with various control interfaces including soft-key, push-button, and touch-screen.

Are Resideo analog thermostats suitable for line-voltage heating applications?

Resideo analog thermostats, such as the TH401, are designed for heat-only applications and can operate at 120V AC or 240V AC. They feature a single-stage SPST open-on-rise switch and a temperature range of 40°F to 85°F. These thermostats are typically used for electric baseboard heaters, radiant floor heating, or other line-voltage heating systems. They include a 5-minute fan delay and push-button control. Ensure the thermostat's voltage and current ratings match the heating load before installation.
