APPLICATION

For on-off control of media temperature in ducts, tanks, liquid

lines, etc.

SPECIFICATIONS

Setpoint Dial Range: Dial plate is marked as °F on one

side and °C on the other. See Table-2 for specific ranges.

Sensing Element: Liquid-filled copper.

Differential: See Table-2.

Dual Bulb Units: One bulb senses the controlled media;

the second bulb senses the outside air temperature. The

temperature of the controlled media increases as outside air

temperature decreases.

DUAL BULB SELECTION Location On the dual bulb units, indoor and outdoor bulbs are determined by the ratio selected (see Table-2). Ratio refers to the outdoor air temperature change compared to the water temperature change. The dial setpoint is the water temperature setpoint when the outdoor temperature is 70°F. Locate the device allowing proper distance to the bulb location. The case can be mounted in any position. Refer to Figure-2 for case dimensions.
