RESIDEO

Resideo is a global provider of home comfort and security solutions, formed in 2018 as a spin-off from Honeywell's Home and Building Technologies division. The brand focuses on HVAC controls, thermostats, sensors, and related components for residential and light commercial applications. 3G Electric supplies a range of Resideo products, including digital and standard thermostats, switching relays, and actuators. These components are designed for heat and cool systems, with options for programmable and non-programmable operation, automatic or manual changeover, and support for conventional and heat pump configurations up to 3 heat/2 cool stages. Resideo thermostats typically operate on 24V AC, feature rectangular shapes with soft-key or push-button controls, and offer temperature differentials of +/-1°F. The product line includes low-voltage models with terminal designations such as C, G, K, L, O, B, R, RC, W, and Y2, enabling compatibility with a variety of HVAC equipment. Switching relays like the R8222N1011 provide reliable control for heating and cooling systems, while actuators such as the T3019DAW0NA are used for valve or damper positioning in HVAC applications. Resideo products are built to standard industry specifications, with no proprietary certifications claimed beyond those inherent to the brand's legacy from Honeywell. 3G Electric stocks these items for global distribution, supporting plant engineers, maintenance managers, and procurement specialists who require consistent, specification-grade components for burner, pump, and gas control systems. The product range emphasizes functional reliability and straightforward integration into existing setups, without marketing embellishments. For technical buyers, Resideo's offerings provide predictable performance metrics—such as voltage ratings, stage counts, and programming schedules—that can be directly compared against project requirements. 3G Electric's logistics support ensures availability of multiple SKUs, with detailed spec sheets accessible for each item.

Frequently asked questions

Common questions about RESIDEO from 3G Electric.

What voltage do Resideo thermostats typically require?

Resideo thermostats supplied by 3G Electric, such as the TH1110U4000 and TH2210U4005, operate on 24V AC. This is standard for low-voltage HVAC systems in residential and light commercial applications. Always verify the specific model's voltage rating before installation, as some units may have different requirements.

Can Resideo thermostats be used with heat pump systems?

Yes, certain Resideo models support heat pump systems. For example, the TH1320U4002/U handles up to 3 heat/2 cool stages for heat pumps. Check the terminal designations (e.g., O/B for reversing valve) and stage count in the product specifications to ensure compatibility with your specific heat pump configuration.

What is the temperature differential on Resideo digital thermostats?

Resideo digital thermostats like the TH1110U4000 have a temperature differential of +/-1°F. This means the thermostat will activate heating or cooling when the room temperature deviates by 1°F from the set point. This specification is consistent across many of their non-programmable models.

Are Resideo switching relays compatible with 24V AC systems?

Yes, Resideo switching relays such as the R8222N1011 are designed for 24V AC control circuits. They are commonly used to switch line-voltage loads like boilers, zone valves, or circulator pumps in HVAC systems. Verify the relay's coil voltage and contact ratings against your application before installation.

What programming options are available on Resideo programmable thermostats?

Resideo programmable thermostats offer various scheduling options. For instance, the TH2210U4005/U supports 5-1-1, 5-2, or 7-day programming, while the TH2110WF4008/U provides 7-day programming. These allow you to set different temperature schedules for weekdays and weekends, or customize each day individually.

Does 3G Electric supply RESIDEO products?

Yes — 3G Electric (S) Pte. Ltd. supplies RESIDEO products. We stock the RESIDEO catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
