VENTILATION OPTIONS
(See Table Below)
Air Conditioning Wall-Mount Model Nomenclature
1
For 0KW and circuit breakers (230/208 Volt) or toggle disconnects (460 Volt) applications, insert 0Z in the KW field of the model number.
See Page 8 for available Factory Installed KW options and Page 9 for Field Installed Heater Packages.
2
Insert “D” for dehumidification with hot gas reheat — Models W42 - 60 only. See Form 7960-572 for complete details.
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. LAC is fan-cycling control for outdoor fan motor on all models except W17A1, which is modulating control.
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 -B or -C 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 -B or -C three phase models. Do not use if
CMC-15 is used.
8
ODT. Outdoor thermostat is adjustable from 0 to 50°F. It is suitable for use as a compressor cut-off 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 airflow, compressor status or filter status. Special economizer required; consult factory.
“V” control module should be ordered in conjunction with direct digital controller (DDC) model TCS24. Refer to DDC specification sheet S3280 for more information.
Option not available for Model W18A.
Use option N for Alarm Relay on Model W18A only.
