Resideo T100B1043 Control
The Resideo T100B1043 Control is a professional-grade thermostatic radiator actuator designed for precise hydronic heating management in high-capacity systems. Engineered for use with V100 and V2000 series radiator valves, this self-powered controller features a 16-foot capillary tube, allowing for remote setpoint adjustment and sensing in large enclosures or hard-to-access areas. By eliminating the need for electrical wiring, the T100B1043 provides a reliable solution for steam or hot water systems, including free-standing radiators and baseboard units. The integrated temperature sensor and dial assembly ensure consistent comfort by maintaining a discharge range of 48°F to 79°F. Constructed with a nickel-plated brass body and a resilient EPDM valve seat disc, this unit ensures tight shutoff and long-term durability in demanding commercial environments. For veteran contractors, the 1-3/16 inch collar and cartridge-based internal parts simplify field service, as all working components are replaceable using the MT100C1016 tool without breaking the system pressure.
Key Benefits
- Extended 16' Capillary: Permits flexible installation of the remote sensor and adjustment dial away from the heat source for hyper-accurate ambient readings.
- Non-Electric Operation: The self-contained liquid thermal element requires no wiring, reducing installation time and overhead in retrofit or new-build projects.
- Professional Durability: Features an industrial-grade plastic housing and a nickel-plated brass fastening ring for resistance against mechanical stress.
- Serviceable Design: Internal cartridge components can be swapped while the valve remains in-line and under pressure, minimizing HVAC system downtime.
- Universal Compatibility: Direct replacement for several major industry models, including Taco 5207, Danfoss RA2000, and Ammark 76L.
Common Questions
Can I install the T100B1043 on any radiator valve?
This actuator is specifically designed for the Resideo V100 and V2000 series valves. It utilizes a 1-3/16" collar diameter; always verify the valve body dimensions and high-capacity requirements of your specific radiator control application before mounting.
What is the benefit of the 16-foot capillary vs. an integral sensor?
An integral sensor can be influenced by the heat radiating directly from the valve or radiator. The 16' remote capillary allows you to mount the thermostat in a location with unobstructed air circulation, providing precise temperature control based on actual room conditions rather than the equipment's surface temperature.
Does this unit require special tools for maintenance?
While the unit is designed for minimal maintenance, you can replace all working parts using the MT100C1016 service tool. This allows you to perform repairs without draining the hydronic system or removing the valve body from the piping.
