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 5 for information on operat-
ing the control.
VAV Units Using RAT or SPT
To configure VAV units using RAT (return air sensor) or SPT
(space temperature sensor), 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 36 for addi-
tional economizer option configurations.
8. See the Exhaust Options section on page 36 for addition
exhaust option configurations.
Multi-Stage CV Units with Mechanical Thermostat
To configure the unit, perform the following:
1. Under Configuration
UNIT
C.TYP, set C.TYP to 3
(TSTAT MULTI).
2. Under the Setpoints menu, set the following configurations:
3. See the Economizer Options section on page 36 for addi-
tional economizer option configurations.
4. See the Exhaust Options section on page 36 for additional
exhaust option configurations.
Multi-Stage CV Units with Space Sensor
To configure the unit, perform the following:
1. Under Configuration
UNIT
C.TYP, set C.TYP to 4
(SPT MULTI).
2. Under the Setpoints menu, the following configurations
should be set:
3. Under the Setpoints submenu, the heating and cooling set
points must be configured:
4. Under Configuration
UNIT
SENS
SPT.S, enable
the space sensor by setting SPT.S to ENBL.
5. Under Configuration
UNIT
FN.MD, set FN.MD to 1
for continuous fan or 0 for automatic fan.
6. To program time schedules, set SCH.N=1 under Configu-
ration
CCN
SC.OV
SCH.N to configure the control
to use local schedules.
7. Under the Timeclock
SCH.L submenu, enter the desired
schedule. See Time Clock section for further descriptions
of these configurations.
8. See the Economizer Options section on page 36 for addi-
tional economizer option configurations.
9. See the Exhaust Options section on page 36 for additional
exhaust option configurations.
