Honeywell Thermostat T104F User Manual

T104F Thermostatic Control The T104F Thermostatic Control is used with a V110 Valve Body to control radiators, convectors, baseboard heating units, or other heating units with standard capacity requirements. The control is self-powered and requires no electrical connection. The T100A includes a setpoint dial and valve actuator, connected by a capillary tube to a sensor. The T104F Control attaches to the valve body by threaded connections and may be mounted at any angle. Install the remote sensor beneath the heating coils in the cold air re- 3 turn, or on a nearby wall where the air flow is not restricted. 2 The setpoint dial has reference marks (1-6). The control has a low limit of 43°F (6°C) when the dial is turned fully clockwise to the frost protection mark*. The red button M9730 indicates the 68°F (20°C) setpoint limit. Higher settings may be made by holding in the button while turning. The thermo- static sensor is protected by a safety spring against tempera- tures to 125°F (52°C). Specifications Fig. 1—T104F dimensions in in. (mm). MATERIALS OF CONSTRUCTION: Body: Industrial grade plastics with low thermal conductivity. Fastening Ring: Plated brass. Internal Parts: Brass thermostat capsule, other metals. 2 1/8 (54) TEMPERATURE RANGE: 43° to 79°F (6° to 26 °C). MAX. SENSOR TEMPERATURE: 125°F (52°C). MAX. OVERALL DIMENSIONS: 2-1/8 in. (54 mm) wide, 3-5/16 in. (84 mm) long. See Fig. 1. 3 5/16 (84) CAPILLARY LENGTH: 6 ft. 8 in. (2 m). MAX. TEMPERATURE SETTINGS: These are the setpoint temperatures, which correspond to the setpoint dial reference marks, under ideal conditions. Factors affecting the temperature at the sensor vary for each M9731 installation. It may be necessary to adjust the setpoint higher or lower to obtain the desired space temperature.
