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-
turn, or on a nearby wall where the air flow is not restricted.
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
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).
