RANGE ss DESCRIPTION /APPLICATION The Lance C12 and C21 series temperature controls are used where a remote bulb thermostat with a narrow differential is required. The sensing element uses a liquid fill which changes volume in direct proportion to a change in temperature. The electrical terminals are located on the back of the C12; on the side of the C21. A popular application of the C control with its double throw switch is on PACT heat/cool units where the bulb senses return air.
