2. Install jumpers between R-W2 and W2-W1 on TB4 in
the control box.
3. Under the Setpoints menu, the following configurations
should be set:
4. The degrees of demand from the space temperature set-
points are configured under the Configuration

D.LV.T
submenu. See the Heating Control and Cooling Control
sections for further description on these configurations.
Configure the following setpoints:

additional exhaust option configurations.
Economizer Options —
Under the Configuration

ECON submenu, the following setpoints may be configured:
Configuration

EC.MN should always be set for
the minimum damper position. While practicing dual setpoint
usage, Cofiguration

EP.MS and EP.XS are needed
to set up the dual minimum damper positions. The controller
would enforce EP.MS

EP.XS .
Indoor Air Quality (IAQ) Options
DEMAND CONTROLLED VENTILATION — Under
Configuration

DCV.C , the following configuration
parameters should be set to establish the minimum and maxi-
mum points for outdoor air damper position during demand
controlled ventilation (DCV):

referenced in the economizer section.
Exhaust Options —
The A Series units can be config-
ured with constant volume 2-stage power exhaust or modulat-
ing power exhaust. The following exhaust options should be
configured.
Configuration

BF.CF =2 (Modulating Power Exhaust
Option) — For modulating exhaust, in the Configuration

Programming Operating Schedules —
The Comfort Link controls will accommodate up to eight dif-
ferent schedules (Periods 1 through 8), and each schedule is
assigned to the desired days of the week. Each schedule
includes an occupied on and off time. As an example, to set an
occupied schedule for 8 AM to 5 PM for Monday through Fri-
day, the user would set days Monday through Friday to ON for
Period 1. Then the user would configure the Period 1 Occupied
From point to 08:00 and the Period 1 Occupied To point to
17:00. To create a different weekend schedule, the user would
use Period 2 and set days Saturday and Sunday to ON with the
desired Occupied On and Off times. To create a schedule, per-
form the following procedure:
NOTE: By default, the time schedule periods are programmed
for 24 hours of occupied operation.
1. Scroll to the Configuration mode, and select CCN
CONFIGURATION ( CCN ). Scroll down to the Schedule
Number ( Configuration

CCN

SC.OV

SCH.N ). If
password protection has been enabled, the user will be
prompted to enter the password before any new data is
accepted. SCH.N has a range of 0 to 99. The default val-
ue is 1. A value of 0 is always occupied, and the unit will
control to its occupied setpoints. A value of 1 means the
unit will follow a local schedule, and a value of 65 to 99
means it will follow a CCN schedule. Schedules 2 to 64
are not used as the control only supports one internal/
local schedule. If one of the 2 to 64 schedules is config-
ured, then the control will force the number back to 1.
Make sure the value is set to 1 to use a local schedule.
2. Enter the Time Clock mode. Scroll down to the LOCAL
TIME SCHEDULE ( SCH.L ) sub-mode, and press
ENTER. Period 1 ( PER.1 ) will be displayed. Press
ENTER to configure Period 1.
