1 HPC. High pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note 3. 2 LPC. Low pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note 3.

3CCM. Compressor control module has adjustable 30-second to 5-minute delay-on-break timer. On initial power-up, or any time the power is interrupted, the delay-on-make will be 2 minutes plus 10% of the delay-on-break setting. There is no delay-on-make during routine operation of the unit. The module also provides the lockout feature (with 1 retry) for

high and/or low-pressure controls, and a 2-minute timed bypass for low-pressure control. 4 LAC. Low ambient control permits cooling operation down to 0°F (-17.7°C)

5 ALR. The alarm relay has a set of normally open and normally closed dry contacts to provide the ability to signal a condition of shutdown on either high or low pressure controls.

6 SK.	PTCR start kit can be used with all -A single phase models. Increases starting torque 2-3x. Not used for -E, -F or -P three phase models. Do not use if SK111 is used.
7 SK.	Start capacitor and potential relay start kit can be used with all -A single phase models. Increases starting torque 9x. Not used for -E, -F or -P three phase models. Do not

use if CMC-15 is used.

8 DDC. Incorporates 4 additional sensors: discharge air temperature, indoor blower airflow, compressor current, and dirty filter. These sensing devices function to input analog data such as temperature, as well as digital data such as airflow, compressor status or filter status.

9 “V” control module should be ordered in conjunction with direct digital controller (DDC) model TCS24. Refer to DDC specification sheet S3280 for more information.
