The C17 is used on air conditioning equipment and provides either manual or automatic heat/Cool change-over. Heating range 64-94°F, Cooling 71-101 with a 3.5°F differential. Rated at 20A@240V motor load, 16A@120V resistive load. Capillary tube is 26". Includes the knob and faceplate.
The C17-100 has two separate electrically isolated SPDT switches for heating and cooling. They are marked on the insulator base as A and B. Each has three separate quick-connect terminals. There are two operating events to each switch ("Cut-In" and "Cut-Out"), making a total fo four switching events that govern the overall performance. Each switch has a minimum of 3 1/2°F differential.
