Resideo T104C1036 Actuator

The Resideo T104C1036 Actuator is a professional-grade high capacity thermostatic radiator actuator designed for the precise automation of two-pipe steam or hot water systems. This non-electric radiator control eliminates the need for external power or wiring, utilizing a robust thermostatic element to modulate flow through radiators, convectors, and baseboard units. Specifically engineered for North American heating applications, the T104C1036 features a remote setpoint and remote sensor configuration with 4.5-foot double capillaries, making it the ideal solution for enclosed cabinets or convector units where the valve body is shielded from representative room air.

This unit ensures consistent comfort by continuously monitoring ambient conditions and adjusting the 1 19/32-inch (40 mm) collar actuator to prevent overheating. The nickel-plated brass construction and EPDM seat disc provide a reliable, tight shutoff, while the cartridge-based design allows for simplified field service. For contractors managing hydronic heating systems, this Resideo radiator valve control provides a field-proven method for achieving zone-level efficiency in high-output environments.

• Precise Hydronic Control: Maintains temperature accuracy between 48°F and 79°F without requiring an electrical power source.
• Optimized for Enclosures: The remote setpoint dial and remote sensor allow for accurate sensing in cold air returns even when the valve is hidden inside cabinetry.
• High Capacity Performance: Specifically designed for the higher flow requirements typically found in commercial and residential steam applications.
• Simplified Maintenance: Compatible with V110 series valve bodies, featuring a replaceable cartridge insert that can be serviced under pressure with the proper tools.
• Double Capillary Versatility: Dual 4.5-foot leads provide significant installation flexibility for complex convector layouts.

How does the remote sensor improve performance in convector cabinets?
In enclosed units, heat trapped near the valve body causes "false sensing." The remote sensor of the T104C1036 is placed in the cold air return to monitor actual room temperature, ensuring the thermostatic radiator valve reacts to real comfort needs rather than trapped heat.

Is the T104C1036 compatible with steam systems?
Yes, this actuator is rated for use with two-pipe steam and hot water systems when paired with the correct V110 valve body, featuring a resilient EPDM disc for high-temperature shutoff.

What is the benefit of a non-electric actuator?
These nonelectric radiator controls reduce installation costs and complexity by removing the need for transformers, wiring, or thermostats, making them a preferred choice for retrofitting older multi-unit buildings.
