The T104B1046 is a high-capacity thermostatic radiator valve actuator with remote sensor and setpoint for precise automatic room temperature control. It modulates hot water or steam flow through radiators and convectors in two-pipe heating systems. The wall-mounted controller connects via capillary tube to the valve-mounted actuator and requires no electricity.

• Remote wall-mounted setpoint and sensor with 16 ft capillary tube to actuator
• For use with V110 series thermostatic radiator valves
• Temperature range 48°F to 79°F (9°C to 26°C)
• 40 mm collar diameter, high capacity design for North American systems
• No electrical connections required, meets ASHRAE Standard 102-1989
• EPDM seat disc for tight shutoff on steam or hot water
