NOTES:
1. Extensive motor and electrical testing on the Carrier units has
ensured that the full horsepower range of the motor can be utilized
with confidence. Using fan motors up to the horsepower

CONTROLS QUICK START
The following section will provide a quick user guide to setting
up and configuring the P Series units with ComfortLink
controls. See Basic Control Usage section on page 3 for information
on operating the control.
Variable Air Volume Units Using Return Air
Sensor or Space Temperature Sensor — To
configure the unit, perform the following:
1. The type of control is configured under Configuration
UNITC.TYP. Set C.TYP to 1 (VAV-RAT) for return
air sensor. Set C.TYP to 2 (VAV-SPT) for space temperature
sensor.
NOTE: For VAV with a space sensor (VAV-SPT), under
ConfigurationUNITSENSSPT.S, enable the
space sensor by setting SPT.S to ENBL.
NOTE: Configuration of the machine control type (C.TYP)
has no effect on whether a unit has a VFD or just a supply fan
installed for static pressure control. No matter what the control
type is, it is possible to run the unit in either CV or VAV mode
provided there are enough stages to accommodate lower air
volumes for VAV operation. Refer to the section on static pressure
control for information on how to set up the unit for the
type of supply fan control desired.
2. The space temperature set points and the supply air set
points are configured under the Setpoints menu. The
heating and cooling set points must be configured. See
the Heating Control and Cooling Control sections for
further description on these configurations. Configure the
following set points:
OHSP Occupied Heat Set point
OCSP Occupied Cool Set point
UHSP Unoccupied Heat Set point
UCSP Unoccupied Cool Set point
GAP Heat-Cool Set point Gap
V.C.ON VAV Occupied Cool On Delta
V.C.OF VAV Occupied Cool Off Delta

nuisance tripping or premature motor failure. Unit warranty will
not be affected.
2. All motors comply with Energy Policy Act (EPACT) Standards
effective October 24, 1997.
Also configure the following points in the Configuration
D.LV.T menu:
L.H.ON Demand Level Low Heat On
L.H.OF Demand Level Low Heat Off
3. To program time schedules, make sure SCH.N=1 under
ConfigurationCCNSC.OVSCH.N to configure
the control to use local schedules.
4. Under the TimeclockSCH.L submenu, enter the desired
schedule. See Time Clock section for further
descriptions of these configurations.
5. Under ConfigurationSPSP.SP, the Supply Duct
Static Pressure set point should be configured.
6. If supply air temperature reset is desired, under the
ConfigurationEDT.R submenu, the following set
points should be configured:
RS.CF EDT Reset Configuration
RTIO Reset Ratio
LIMT Reset Limit
RES.S EDT 4-20 mA Reset Input
This applies to both TSTAT MULTI and SENSOR
MULTI modes.
NOTE: Configure either RTIO and LIMT or RES.S. All three
are not used.
7. See the Economizer Options section on page 33 for additional
economizer option configurations.
8. See the Exhaust Options section on page 33 for addition
exhaust option configurations.
Multi-Stage Constant Volume Units with
Mechanical Thermostat — To configure the unit, perform
the following:
1. Under ConfigurationUNITC.TYP, set C.TYP to 3
(TSTAT MULTI).
