Air Conditioning Wall-Mount Model Nomenclature
1
For 0KW and circuit breakers (230/208 Volt) or pull
disconnects (460 Volt) applications, insert 0Z in the KW
field of the model number.
TYPE
Air Conditioner
STD = Standard equipment for these specified models.
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
.
3
CCM 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.
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 is standard with all -A single phase models only. Increases starting torque 2-3x. Must be disconnected if SK111 or SK113 is used. Is not used
or available for -B or -C three phase models.
7
Start capacitor and potential relay start kit can be used with all -A single phase models. Increases starting torque 9x. Not used for -B or -C three phase models. Do
not use if CMC-15 is used. Use SK111 for W61A1-A only. Use SK113 for W38A1-A and W49A1-A only.
8
ODT. Outdoor thermostat is adjustable from 0 to 50°F. It is suitable for use as a compressor cutoff thermostat.
9
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 air flow, compressor status or filter status.
“V” control module should be ordered in conjunction w/direct digital controller (DDC) model TCS24. Refer to DDC specification sheet S3280 for more information.
