CONTROLS QUICK START
The following section will provide a quick user guide to setting
up and configuring the P Series units with
Comfort
Link con-
trols. See Basic Control Usage section on page 4 for informa-
tion on operating the control.
VAV 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
UNIT
C.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
Configu-
ration
UNIT
SENS
SPT.S
, enable the space sensor by set-
ting
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 in-
stalled 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 vol-
umes 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 heat-
ing and cooling set points must be configured. See the
Heating Control and Cooling Control sections for further
description on these configurations. Configure the follow-
ing set points:
Also configure the following points in the
Configuration
D.LV.T
menu:
3. To program time schedules, make sure
SCH.N
=1 under
Configuration
CCN
SC.OV
SCH.N
to configure the
control to use local schedules.
4. Under the
Timeclock
SCH.L
submenu, enter the desired
schedule. See Time Clock section for further descriptions
of these configurations.
5. Under
Configuration
SP
SP.SP
, the Supply Duct
Static Pressure set point should be configured.
6. If supply air temperature reset is desired, under the
Con-
figuration
EDT.R
submenu, the following set points
should be configured:
This applies to both TSTAT MULTI and SENSOR MULTI
modes.
NOTE: Configure either
RTIO
and
LIMT
or
RES.S
. Do not use
all three.
7. See the Economizer Options section on page 34 for addi-
tional economizer option configurations.
8. See the Exhaust Options section on page 34 for addition
exhaust option configurations.
